Answer:

g(4) = 157

Step-by-step explanation:

g(x) = 8x^2 + 9x - 7

Let x =4

g(4) = 8 * 4^2 +9*4 -7

=8*16 +36 - 7

=128+36-7

=157

Answer:

157

Step-by-step explanation:

g(x)=

${8x}^{2} + 9x - 7$

g(4) =

$8( {4})^{2} + 9(4) - 7 \\g(4) = 8 \times 16 + 36 - 7 \\ g(4) = 128 + 29 \\ g(4) = 157$

It would be 82 2/3 since 1/3 minis 2/3 would equal -1/3 you subtract that from 83 and get 82 2/3

Let f(x)=−32x and g(x)=(12)x−1 . Graph the functions on the same coordinate plane. What are the solutions to the equation f

Grace [21]

Refer to the attachment for the graph of the two functions in Desmos. To solve for the solution, we just equate the two functions and solve for x:

$-32x=12x-1$
$-44x=-1$
$x= \frac{1}{44}$

For the y value we just substitute x in any of the function:
$f( \frac{1}{44})=-32( \frac{1}{44})=- \frac{8}{11}$

ANSWER: The solution to the equation f(x)=g(x) is ( $\frac{1}{44}$ , $\frac{-8}{11}$ ).
