Consider the inequality -5(x+7)<-10. Write an Inequality representing the solution for x.

1 answer:

7 0

It could be 3 and lower because if you - 7 from -10 you get -17 then your equation would be -5x< -17 than you divide -17 by -5 and get 3.4 than your equation is x < 3.4 so your answer is 3.4 or below.

Answer:

a = 8, b = $\frac{3}{2}$

Step-by-step explanation:

Given the exponential function

f(x) = a $b^{x}$

To find a and b use the given coordinate points on the graph

Using (0, 8 ), then

8 = a $b^{0}$ [ $b^{0}$ = 1 ] , then

a = 8

f(x) = 8 $b^{x}$

Using (2, 18 ) , then

18 = 8b² ( divide both sides by 8 )

$\frac{18}{8}$ = b² , that is

b² = $\frac{9}{4}$ ( take the square root of both sides )

b = $\sqrt{\frac{9}{4} }$ = $\frac{3}{2}$

Thus

f(x) = 8 $(\frac{3}{2}) ^{x}$
