3) y = 4x + 24
y = x + 9

x= -5

y= 4

Step-by-step explanation:

Substitute the equations for y

x+9=4x+24

Subtract x from both sides of the equation.

9=3x+24

Now subtract 24 from both sides of the equation.

-15=3x

x= -5

y= -5=9=4

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
