Answer:
Step-by-step explanation:
11. Point (0,4) m=2
y-y1 = m(x-x1)
y - 4 = 2(x -0 )
y-4 =2x
y = 2x+4
12. (3,5) and (9,3)
m = (3-5) / (9-3)
m = -2 / 6 = -1/3
y-y1 = m(x-x1)
y - 5 = (-1/3) (x - 3)
3y -15 = -(x-3)
3y = -x + 3 +15
3y = -x +18
13. y = -x/3 + 6
14. 3x - 5y = 15
-5y = -3x +15
divide by -5 throughout
y = (3/5)x - 3

Answer:
its c
Step-by-step explanation:
Our denominators are 40 and 4. What we need to do is find the lowest common denominator of the two numbers. This is the smallest number that can be divided by both 40 and 4. In this case, the lowest common denominator is 40.
If we multiply the first denominator (40) by 1 we will get 40. If we multiply the second denominator (4) by 10 we will also get 40. We also need to multiply the numerators above the line by the same amounts so that the fraction values are correct:
33 x 1
40 x 1
3 x 10
4 x 10
This is what 33/40 and 3/4 looks like with the same denominator:
33
40
&
30
40
Now that these fractions have been converted to have the same denominator, we can clearly see by looking at the numerators that 33 is greater than 30 which also means that 33/40 is greater than 3/4.

Which is more, 7 feet or 81 inches?
Answer: 7 feet
Step-by-step explanation:
1 foot = 12 inches
7 * 12 = 84
7 feet = 84 inches
84 inches are more than 81 inches
Answer:
7 feet is greater
Step-by-step explanation:
you can change feet to inches. one foot is the same as 12 inches. so 7 feet = 84 inches. so 84 > 81 so 7 feet is greater

Mrs. aviles is planning a fruit-cup party for a class of 18 students and two teachers. She spends $10 for a package of snacks and also takes orders in advance for fruit cups that cost $3 each.
1. describe the domain of the function both in words and numbers?
2. what is the range?
Answer:
domain is x = 3
Thus domain means that for every fruit cup costs $3
Range is f(20) = 60
Step-by-step explanation:
We are given;
Total students for the fruit cup party = 18
Total teachers for the fruit cup party = 2
Cost of each fruit cup =$ 3
Delivery charge = $ 10
Now, the total number of people attending the party = Total number of students + Total number of teachers
Thus;
Total number of people attending party = 18 + 2 = 20
Since cost of each fruit cup is $3.
Thus, for 20 fruit cups, the function is;
f(x) = 20x where x is cost of each fruit cup.
It means the cost of 20 fruit cups = $3 × 20 = $60
Thus, domain is x = 3
Thus domain means that for every fruit cup costs $3
Range is f(20) = 60

+4>-3x-8
Simplify your answer as much as possible.
We need to know about inequality to solve this problem. The solution of the inequality is x>-4/3.
Inequality represents the comparison between two unequal expressions. Two expressions can be related to each other as greater than, less than,greater than or equal to or less than or equal to. While solving inequality we always have to keep in mind the change of sign and corresponding change of the comparison. Here in the question we have an inequality of the variable x, we have to get a solution for x by solving this inequality.
6x+4>-3x-8
6x+3x>-8-4
9x>-12
x>-4/3
Therefore the solution set that we get from the inequality 6x+4>-3x-8 is x>-4/3.

Option A is correct.
Step-by-step explanation:
9) We need to solve:

Solving using quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a=1, b=8 and c=58
Putting values and finding value of x
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-8\pm\sqrt{(8)^2-4(1)(58)}}{2(1)}\\x=\frac{-8\pm\sqrt{64-232}}{2}\\x=\frac{-8\pm\sqrt{-168}}{2}\\We\:know\sqrt{-1}=i \\x=\frac{-8\pm2\sqrt{42}\:i}{2}\\x=\frac{2(-4\pm\sqrt{42}\:i)}{2}\\x=\frac{2(-4+\sqrt{42}\:i)}{2}, x=\frac{2(-4-\sqrt{42}\:i)}{2}\\x=-4+\sqrt{42}\:i, x=-4-\sqrt{42}\:i[/tex]

-8(6x+12)=-32x-24 SHOW YOUR WORK PLS whats x
Answer:
x= -9/2
Hope I helped
Answer:
[tex]x=-\frac{9}{2}[/tex]
Step-by-step explanation:
Simplify the given equation by solving for x. Isolate the x variable in:
[tex]-8(6x+12)=-32x-24[/tex]
Expand the left side by using the distributive property. Remember that when a negative and positive are multiplied, the result is always negative:
[tex]-8(6x)-8(12)=-32x-24\\\\-48x-96=-32x-24[/tex]
Use inverse operations to isolate the variable. Add 96 to both sides, canceling out the -96 on the left:
[tex]-48x-96+96=-32x-24+96\\\\-48x=-32x+72[/tex]
Add 32x to both sides to isolate x:
[tex]-48x+32x=-32x+32x+72\\\\-16x=72[/tex]
Now divide both sides by 16:
[tex]\frac{-16x}{16} =\frac{72}{16} \\\\-x=\frac{9}{2}[/tex]
Make the variable positive by multiplying both sides by -1:
[tex]-1(-x)=-1(\frac{9}{2})\\\\x=-\frac{9}{2}[/tex]
:Done
Note:
You do the same thing to both sides in order to keep the equation balanced. Using the opposite value of a term cancels it out, moving it to the other side.

O 29.2 centimeters
Lo
Answer:
O 20.8 centimeters
Step-by-step explanation:
Guessed on Edge and got it right.
The perimeter of the square after 1.5 seconds will be 20.8 centimeters so option (C) will be correct.
What is the perimeter?Perimeter is the addition of an external measure of sides it will always positive.
Perimeter of square = side + side + side + side
Initial side length of square = 1 cm
Rate of grow side = 2.8 centimeter per minutes
By multiplying 1.5
Rate of grow side = 4.2 centimeter per 1.5 minute
So,
New side = 1 + 4.2 = 5.2 cm
Perimeter = 4 × side
Perimeter = 4 (2.5) = 20.8 cm
Hence "The perimeter of the square after 1.5 seconds will be 20.8 centimeters".

A ski jump rises 3ft over a run of 7ft what is the length of the surface of the jump?
Answer:
7.6158 feet
Step-by-step explanation:
The rise and run form the shorter sides of a right triangle with the hypotenuse as the surface (see figure)
Hypotenuse (surface length) is given by the Pythagorean formula
[tex]c = \sqrt{a^2 + b^2}[/tex] where c is the hypotenuse and a, b the shorter sides
Here
