Answer:
D
Step-by-step explanation:
If you are told that the slope is 2 that means that the equation cannot be A.
The slope is the number in front of the x. So far what you know is that
y = 2x + b
b is found from the given point.
- 7 = 2*(-8) + b Expand the right side
- 7 = - 16 + b Add 16 to both sides
- 7+16 = -16 + 16 + b
- 23 = b
answer y = 2x + 23
The answer is D
Answer:
Simone is correct
Step-by-step explanation:
Given
Line 1:


Line 2:


Required
Is Simone correct?
Slope (m) is calculated using:

For Line 1




For Line 2:


Divide by 2/2



By comparison, both lines have the same slope.
Hence, Simone is correct
50 and 133 i would say but i am not 100% sure
For these questions to be true and the equation of the tangent to have an equal y to the equation of the parabola i guess there has to be a "c" and in that case integrate the equation of the tangent you will have a = 5 and b = -18 then you substitute in the equation of the parabola with the point you have you will find that "c" = 21 and so the equation of the parabola becomes y = 5x^2 - 18 x +21
2/3 of 18...." of " means multiply
2/3 * 18 = 36/3 = 12....she has memorized 12 words so far
