Answer:

x = 4 or x = -10 for equation x^2 + 6x = 40

Step-by-step explanation:

x^2 + 6 = 40

x^2 = 40 - 6

x^2 = 34

x = root(34) or x = -root(34) but this is not in the answer choice.

is it x^2 + 6x = 40

x^2 + 6x + 9 = 40 +9

(x + 3)^2 = 49

x + 3 = 7 or x + 3 = -7

x = 4 or x = -10

Write the formula for an exponential function with initial value 300 and decay factor 0.73

postnew [5]

Answer: 300*0.73^x

Step-by-step explanation:

300 is the initial value and every time x goes up by 1, the value get multiplied by 0.73

when x=3

then the value would be 300*0.73*0.73*0.73 or 300*0.73^3

then for x amount of times the equation would be 300*(0.73 x times ) or 300*0.73^x
