Answer:
x = -5
y = -5
Step-by-step explanation:
-8y+9x = -5; 8y+7x = -75
Add the two equations together to eliminate y
-8y+9x = -5
8y+7x = -75
----------------------
0y + 16x = -80
Divide each side by 16
16x/16 = -80/16
x = -5
Now find y
8y+7x = -75
8y+7(-5) = -75
8y-35 = -75
Add 35 to each side
8y = -40
Divide by 8
8y/8 = -40/8
y = -5
Answer:
[tex]\boxed{x=-5}\\ \boxed{y=-5}[/tex]
Step-by-step explanation:
-8y + 9x = -5
8y + 7x = -75
Add the equations (eliminating the y-variable).
16x = -80
Divide both sides by 16.
[tex]\frac{16x}{16}[/tex] = [tex]\frac{-80}{16}[/tex]
x = -5
Plug x as -5 in the first equation to find y.
-8y + 9(-5) = -5
-8y +-45 = -5
Add 40 to both sides.
-8y = 40
Divide both sides by -8.
[tex]\frac{-8y}{-8}[/tex] = [tex]\frac{40}{-8}[/tex]
y = -5

Answer:
[tex] r = 17.3 [/tex]
Step-by-step explanation:
We are given the following:
m < T = 87°
TV = u = 11
TU = v = 14
UV = t = ?
Use the Law of Cosines to solve for the value of t as explained below:
[tex] t^2 = u^2 + v^2 - 2(u)(v)*cos(T) [/tex]
[tex] r^2 = 11^2 + 14^2 - 2(11)(14)*cos(87) [/tex]
[tex] r^2 = 121 + 196 - 16.12 [/tex]
[tex] r^2 = 317 - 16.12 [/tex]
[tex] r^2 = 300.88 [/tex]
[tex] r = \sqrt{300.88} [/tex]
[tex] r = 17.3 [/tex] (to the nearest tenth)
Alice is thinking of a number n that she wants her sister to guess. Her first clue is that two less than six times her number is between ten and thirty-four (inclusive). Write a compound inequality that shows the range of numbers that Alice might be thinking of.
Answer:
10 < 6n -2 ≤ 34
n= {3, 4, 5, 6}
Step-by-step explanation:
number
⇒ n
two less than six times the number
⇒ 6n -2
it is between ten and thirty-four (inclusive)
⇒ 10 < 6n -2 ≤ 34
we can solve it as:
10 < 6n -2 ≤ 34 ⇒ add 2 to all sides12 < 6n ≤ 36 ⇒ divide by 6 all sides2 < n ≤ 6n= (2, 6]or
n= {3, 4, 5, 6}Answer:
[2,6]
Step-by-step explanation:
Translate to an inequality. Since two less than six times her number is at least ten and at most thirty-four, we have the following inequality.
10≤6n−2≤34
Solve the compound inequality by isolating the variable in the center.
10≤6n−2≤3412≤6n≤362≤n≤6
Finally, write your answer in interval notation. The inequality includes all values between 2 and 6 including the end values, therefore the final answer is:

you are having a pizza making party. You will need 6 ounces of dough and 4 ounces of sauce for each person at the party (including myself the host) Once you have a total count of guests you have exactly the amount needed for ingredients. the dough and sauce that I have is 130 ounces all together. How many ounces of dough did I buy? Explain How many ounces of sauce did I buy? Explain How many guests are coming to the party? Explain
Answer: 78 ounces of dough was bought.
52 ounces of sauce was bought.
There were 13 guests .
Step-by-step explanation:
Let x = Number of guests
As per given, For each person 6 ounces of dough and 4 ounces of sauce is required.
i.e. Total ounces of dough and sauce together required = 6+4=10
The dough and sauce is 130 ounces all together.
i.e. [tex]10x=130[/tex]
Divide both sides by 10 , we get
x= 13
i.e. there were 13 guests .
Total ounces of dough = 6 x ( Number of guests) = 6 x 13= 78 ounces
hence, 78 ounces of dough was bought.
Total ounces of sauce = 4 x ( Number of guests) = 4 x 13= 52 ounces
hence, 52 ounces of sauce was bought.
The total ounces of dough is 78 ounces
The total ounces of sauce is 52 ounces
The total number of guests is 13
The equation that can be used to represent the question given is:
6a + 4a = 130
Where a represents the number of guests at the party.
The above equation means that the total ounces of dough and sauce bought is a function of the number of guests at the party. These total ounces is equal to 130.
6a + 4a = 130
10a = 130
a = 130 / 10
a = total number of guests = 13
The total ounces of dough = 13 x 6 = 78 ounces
The total ounces of sauce = 13 x 4 = 52 ounces

Answer:
6. Unit rate = 1.3 yards per second
7. Unit rate = 0.8 page per minute
Step-by-step explanation:
The unit rate is simply the comparison of 2 quantities, whereby dividing both, the denominator must be 1.
For example, in the graph given comparing distance walked over time, when x (time in s) = 3, y (distance in yd) = 4.
Unit rate represented by the slope is the yards covered per second.
Unit rate = [tex] \frac{4}{3} = 1.33 [/tex]
Unit rate ≈ 1.3 yards per second
For the second graph given, unit rate of the slope is the number of pages read per minute.
From the graph, 4 pages is read at 5 minutes.
Thus,
Unit rate = [tex] \frac{4}{5} = 0.8 [/tex]
Unit rate = 0.8 page per minute

We are talking about exponents here, which is the power to which a number is raised. What does it mean to raise a number to a power? It means to multiply it a certain number times.
For example, 3 to the the 3rd power is 27 because you multiply 3 three times (3×3×3), giving you 27.
We have 2×2×2×2×2. We see that we have the number 2 and need to raise it to a certain power. Since there are 5 2s, we are raising to the 5th power.
Therefore, the answer is B.) 2 to the 5 power.

Write the equations after translating the graph of y=|1/2x-2|+3. One unit to the left
Answer:
[tex]g(x) = |\frac{1}{2}x - \frac{3}{2} | + 3[/tex]
Step-by-step explanation:
Given
[tex]y = |\frac{1}{2}x - 2| + 3[/tex]
Required
Translate the above one unit to the left
Replace y with f(x)
[tex]y = |\frac{1}{2}x - 2| + 3[/tex]
[tex]f(x) = |\frac{1}{2}x - 2| + 3[/tex]
When an absolute function is translated to the left, the resulting function is
[tex]g(x) = f(x - h)[/tex]
Because it is been translated 1 unit to the left, h = -1
[tex]g(x) = f(x - (-1))[/tex]
[tex]g(x) = f(x + 1)[/tex]
Calculating [tex]f(x+1)[/tex]
[tex]f(x+1) = |\frac{1}{2}(x+1) - 2| + 3[/tex]
Open bracket
[tex]f(x+1) = |\frac{1}{2}x + \frac{1}{2} - 2| + 3[/tex]
[tex]f(x+1) = |\frac{1}{2}x + \frac{1-4}{2} | + 3[/tex]
[tex]f(x+1) = |\frac{1}{2}x + \frac{-3}{2} | + 3[/tex]
[tex]f(x+1) = |\frac{1}{2}x - \frac{3}{2} | + 3[/tex]
Recall that
[tex]g(x) = f(x + 1)[/tex]
Hence;
[tex]g(x) = |\frac{1}{2}x - \frac{3}{2} | + 3[/tex]

Answer:
x = 60
Step-by-step explanation:
In a circle, the sum of the angles that meet at a point is 360 degrees. So now that we have the total, we can subtract all the given information in the picture. We have 84, 75, 68, and x + 73. Now let us set up and equation for this problem.
360 = 84 + 75 + 68 + x + 73
Now combine like terms.
360 = x + 300
Now subtract 300 on both sides.
x = 60
And this is the value of x.
Answer:
50 degrees
Step-by-step explanation:
84 + 75 + 68 = 227
227 - 360 = 133
133 - 73 = 50
The answer is 50 degrees.
Is (0, 3) a solution to the following system?
Y=-x+3
Y=2x-3
A No, because it does not check in either equation.
B. No, because it does not check in the first equation.
C. No, because it does not check in the second equation.
D. Yes, because it checks in both equations.
Solve each equation with (0, 3)
y = -x + 3
3 = -0 + 3
y = 3 (correct since y = 3 in (0, 3))
y = 2x - 3
3 = 2(0) - 3
3 = 0 - 3
3 = -3 (incorrect since it isn't equal)
So... No, because it does not check in the second equation.

Select the correct answer. The capacity in cubic feet of a cylindrical silo is given by the function C(x), where x is the radius of the silo in feet. The area of the circular base of the silo is given by the function A(x). C(x) = 6.28x3 + 18.84x2 A(x) = 3.14x2 Which function, H(x), represents the height of the silo? H(x) = x + 3 H(x) = 2x − 6 H(x) = 2x + 6 H(x) = x − 3
Answer:
C. H(x) = 2x+6
Step-by-step explanation:
Volume of the cylindrical silo = Area of its circular base × Height
Volume of the cylindrical silo = πr²×H
If the area of the circular base of the silo is given by the function A(x), the volume is given by C(x) and the height is given by H(x), the formula can be expressed as;
C(x) = A(x) × H(x)
The height of the cylindrical silo will be;
H(x) = C(x)/A(x)
Given C(x) = 6.28x³ + 18.84x² and
A(x) = 3.14x²
H(x) = 6.28x³ + 18.84x²/3.14x²
H(x) = x²(6.28x+18.84)/3.14x²
H(x) = (6.28x+18.84)/3.14
H(x) = 3.14(2x+6)/3.14
H(x) = 2x+6
Hence, the function, H(x) that represents the height of the silo is 2x+6.

A stick has a length of $5$ units. The stick is then broken at two points, chosen at random. What is the probability that all three resulting pieces are longer than $1$ unit?
Answer:
4/25 = 0.16
Step-by-step explanation:
The shortest stick must be between 0 and 5/3. The probability that it is longer than 1 is therefore:
(5/3 − 1) / (5/3 − 0)
(2/3) / (5/3)
2/5
So the probability that both of the shortest sticks are longer than 1 is (2/5)² = 4/25.

Answer:
The value of x is 5 units.
Step-by-step explanation:
Complete Question
In the figure CD is the perpendicular bisector of AB. If the length of AC is 2x and the length of BC is 3x - 5 . The value of x is ?
The figure is presented in the attached image to this solution.
Solution
Using the concept of similar triangles,
We can prove that triangles CDA is similar to triangle CDB.
This can be proved using the SAS congruence property that two sides and an angle between them are the same.
- Side AD = Side DB (Given in the diagram)
- Angle CDA = Angle CDB = 90° (Also evident from the diagram)
- Side CD = Side CD (common side to the two triangles)
Hence, it is evident that
Side AC = Side CB

At a fun park, the cost of a rollercoaster ride and a ferris wheel ride is $10. The cost of a Gravitron ride and a Ferris wheel ride is $12. The cost of a rollercoaster ride and a Gravitron ride is $14. What is the cost of each ride?
Answer:
r = cost of rollercoaster = 6
f = cost of ferris wheel=4
g = cost of graviton=8
Step-by-step explanation:
r = cost of rollercoaster
f = cost of ferris wheel
g = cost of graviton
r+f = 10
g+f = 12
r+g = 14
Take the third equation and subtract the first equation
r+g =14
-r-f = -10
-------------------
g-f = 4
Take this and add it to the second equation
g-f = 4
g+f = 12
-------------------
2g = 16
Divide by 2
g = 8
Now find f
g+f = 12
8+f = 12
f = 12-8
f=4
Now find r
r+g =14
r+8 =14
r = 14-8
r = 6
