Answer:

A, D, E, F

Step-by-step explanation:

the y-intercept is the b part of the equation of a line : y=mx+b.

so, for example, A. y=3x-8 has a y-intercept of -8

and B. y=3x-9 has a y-intercept of -9

and C. y= 3x+8 has a y-int of 8

and so on.

Answer:    f'(1)=\dfrac{4}{2y+1}

<u>Step-by-step explanation:</u>

To find the tangent, you need to find the derivative with respect to x.

Then substitute x = 1 into the derivative.

Given:         0 = 2x² - xy - y²

Derivative:  0 = 4x - y' - 2yy'

Solve for y': 2yy' + y' = 4x

                   y'(2y + 1) = 4x

                   y'=\dfrac{4x}{2y+1}

\text{Substitute x = 1:}\quad y'(1)=\dfrac{4}{2y+1}

The product of a number and -7 amounts to seven times the sum of that number and 20. Find the number.
MA_775_DIABLO [31]

Answer: -10

Step-by-step explanation:

If you put it in an equation it would be -7x=7(x+20). You would then -7x to both sides to get -14x=140. Just divide -14 on both sides to isolate x. This equates to -10. If you put -10 back into the equation then it says that 70 is 7 times larger than 10. Which it is.
