Answer:

X=5, y=-8

Step-by-step explanation:

-X + y =-13 equation 1

-8x-4y=-8 equation 2

4(-x+y)=4(-13). Multiply equation 1 by 4 to eliminate y

-4x + 4y =-52

———————————-

-4x + 4y =-52 equation 1 after multiplying by 4

-8x-4y=-8. Equation 2

-12x=-60 added 2 equations above

x=5

solve for y

-x+y=-13

-5+y=-13

y=-8

What is the difference quotient of the function g(x) = 4^x

lidiya [134]

Answer:

First choice

Step-by-step explanation:

The difference quotient in general is $\frac{g(x+h)-g(x)}{h}$ . To get an expression for $g(x+h)$ , replace x with x + h.

For this question,

$\frac{4^{x+h}-4^x}{h}=\frac{4^x\cdot4^h-4^x}{h}$

Factor $4^x$ out of the numerator.

$\frac{4^x(4^h-1)}{h}$
