Answer:
x = 2
Step-by-step explanation:
5(2x- 6) + 20 = 10
10x - 30 = -10
10x = 20
x = 2
Answer:
O2
Step-by-step explanation:
5(2x-6)+20=10
Use distirbutive property:
10x-30 because, 5×2 = 10, and 5×6=30
Now we have
10x-30+20=10
Now combine the like terms
10x-10=10
Send the 10 to the other side(it turns into positive 10 because it was negative 10 on the other side)
10x = 10+10
10x=20
Divide 10 by both sides
x/10 = 20/10
x=2

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.
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.
Best of Luck!

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:
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
What is the solution to the system of equations?
y= 2/3x+3
x = –2
Answer:
[tex]x = -2[/tex] and [tex]y = \frac{5}{3}[/tex]
Step-by-step explanation:
Given
[tex]y = \frac{2}{3}x + 3[/tex]
[tex]x = -2[/tex]
Required
Determine the solution to the equations
From the second equation, we have the value of x already;
The next step is to substitute -2 for x in the first equation
[tex]y = \frac{2}{3}x + 3[/tex] becomes
[tex]y = \frac{2}{3}(-2) + 3[/tex]
[tex]y = \frac{-4}{3} + 3[/tex]
[tex]y = -\frac{4}{3} + 3[/tex]
Take LCM
[tex]y = \frac{-4 + 9}{3}[/tex]
[tex]y = \frac{5}{3}[/tex]
Hence,
[tex]x = -2[/tex] and [tex]y = \frac{5}{3}[/tex]

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.

Answer:
(-15,3)
Step-by-step explanation:
Answer:
No, Beth is not correct. The function g(x) has an h value of 5 and a k value of 1. This would be a horizontal translation of the square root function of 5 units to the right, rather than the left. Beth was correct about the vertical translation of the square root function of 1 unit up. The point (0, 0) from the square root function would be translated to the point (5, 1) on the graph of g(x).

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

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.

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

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.
Given each set of vertices, determine whether PQRS is a rhombus, a rectangle, or a square. List all that apply. Explain your reasoning, P(-2, -3). Q(2, - 6). R(6. - 3). S(2, 1)
Answer:
RectangleStep-by-step explanation:
Given the coordinates P(-2, -3). Q(2, - 6). R(6. - 3). S(2, 1), to determine the type of shape the quadrilateral is, we need to find the measure of the sides. To get the measure of each sides, we will take the distance between the adjacent coordinates using the formula to formula for calculating the distance between two points as shown;
D = √(x₂-x₁)²-(y₂-y₁)²
For the side PQ with the coordinate P(-2, -3). Q(2, - 6)
PQ = √(2-(-2))²-(-6-(-3))²
PQ = √(2+2)²-(-6+3)²
PQ = √4²-(-3)²
PQ = √16-9
PQ = √7
For the side QR with the coordinate Q(2, - 6) and R(6, -3)
QR = √(6-2))²-(-3-(-6))²
QR = √(4)²-(3)²
QR = √16-9
QR = √7
For the side RS with the coordinate R(6. - 3) and S(2, 1)
RS = √(2-6)²-(1-(-3))²
RS = √(-4)²-(1+3)²
RS = √16-(4)²
RS = √16-16
RS = 0
For the side PS with the coordinate P(-2, -3) and S(2, 1)
PS = √(2-(-2))²-(1-(-3))²
PS = √(4)²-(1+3)²
PS = √16-(4)²
PS = √16-16
PS = 0
For the quadrilateral to be a rectangle, then two of its sides must be equal and parallel to each other. A rectangle is a plane shape that has two of its adjacent sides equal and parallel to each other. Since two of he sides are equal i.e RS = PS and PQ = QR then the quadrilateral PQRS is a rectangle. Both rhombus and square has all of its sides equal thereby making them wrong.
