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

One method to solve is to rewrite 9 as a power of 3 and then equate exponents to solve for x
3^x = 9^(x+2)
3^x = (3^2)^(x+2)
3^x = 3^(2(x+2))
x = 2(x+2) <<-- bases are equal, so exponents must be equal
x = 2x+4
x-2x = 4
-x = 4
x = -4
Answer: x = -4
Answer: 7
Step-by-step explanation:
Write as a decimal

Rounding a decimal to the nearest whole number
If you have a decimal that is greater than or equal to 5 in the tenths place then you round up. Ex: 5.8 would be rounded to 6, 1.5 would be rounded to 2.
If you have a decimal that is less than or equal to 4 in the tenths place then you round down. Ex: 5.1 would be rounded 5, 1.2 would be rounded to 1.
Since 0 is in the tenth’s place we round down to 7.
Answer:
(2,-7)
Step-by-step explanation:
Plug in the numbers to test and see if it gives you -17 and -8.
Option 1. 2(-4)+3(2)
= -8+6 = -2. Not it.
Option 2. 2(2)+3(-7)
4 - 21 = -17 Works. Try the second equation to make sure.
3(2)+2(-7)
6-14 = -8. Works.
(2,-7) is the answer.
