What valur of x makes the equation below true? 9^5 * 9^7=9^x

klasskru [66]

Answer:

x=12

Step-by-step explanation:

(9^5)(9^7)=9^x

282429536481=9^x

Step 1: Flip the equation.

9^x=282429536481

Step 2: Solve Exponent.

9^x=282429536481

log(9^x)=log(282429536481)(Take log of both sides)

x*(log(9))=log(282429536481)

x=log(282429536481)/log(9)

x=12

Find the slope of the line that passes through (2, 11) and (7, 4).

EleoNora [17]

Answer:

$\large\boxed{-\dfrac{7}{5}}$

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (2, 11) and (7, 4).

Substitute:

$m=\dfrac{4-11}{7-2}=\dfrac{-7}{5}=-\dfrac{7}{5}$
