y' = limit 5/(x + h) - 5/x / h where h is a small increase in x


= 5x - 5x - 5h / xh(x + h)


= -5h / xh(x+ h)

= -5 / x^2 + hx


As h approaches zero hx approaches 0


so y' = limit of -5 (x^2 + hx) = -5 / x^2 (answer)

The solution to a system of two linear equations is (4, -3). One equation has a slope of 4. The slope of the other line is the n
astraxan [27]

Answer:

Hello,

First equation is false

Second equation is true

Step-by-step explanation:

1)

(4,-3) is a point of the line y=4x-19  since

-3=?4*4-19

-3=-3

2)

(4,-3) is not a point of the line y=1/4x-2 since

-3=? 1/4*4-2

-3=? 1-2

-3≠-1

I have written that because it is difficult for me to understand

"the negative reciprocal of the slope of the first"

the negative reciprocal of 4 should be -1/4.

Equation y=1/4x-2 is false.
