Step-by-step explanation: Let's make the equations first,
Plan A: 70x Plan B: 50x+500
Now we make it into an equivalent equation:
70x=50x+500
Then we solve:
70x=50x+500
-50x -50x
20x=500
÷20 ÷20
x=25
To check if it's correct, we just plug it in:
70(25)=50(25)+500
1750=1750
The slope is the change in y-axis to x-axis of a graph. The slope of the line given is -10
<h3>How to find the slope of a line?</h3>
The standard equation of a line in slope intercept form is given as y = mx+b
where
- m is the slope
- b is the y-intercept
Given the equation y = -10x - 2
Compare
mx = -10x
m = -10
Hence the slope of the line given is -10

We are given with the data of a parabola with vertex at (2, 2) and directrix at <span>y = 2.5. the formua should be ax^2 + b x + c = y because of the directrix.
(x-h)^2 = 4a (y-k)
(x-2)^2 =4a (y-2)
a is the equidistant distance from focus to vertex and from vertex to directrix that is equal to -0.5
then the answer is
</span>(x-2)^2 =-0.5*4 (y-2)
<span>x2 - 4x + 4 = -2y +4
x2-4x+2y = 0
answer is C

Hello!
You find the volume of a rectangular prism if the length is x, the width is x2, and the height is 5x2 + 4x + 1. Use the formula
<span>V = l ⋅ w ⋅ h, where l is length, w is width, and h is height, to find the volume.
</span>
Solution:
So in this Case, we can see that the Length = x, Width = x², and Height = 5x2 + 4x + 1. Remember: (V = l . w . h)<span>
Use the formula:</span>
<span>V = l ⋅ w ⋅ h,=x×x²×(5x²+4x+1)
</span>
<span>=x³×(5x²+4x+1)
</span>
=5x^5+4x^4+x³

Answer:
Step-by-step explanation:
(10 - 8)/(-21 + 9)= 12/-12= -1
y - 8 = -1(x + 9)
y - 8 = -x - 9
y = -x - 1
