Answer:

x= 5

Step-by-step explanation:

First, subtract the smallest variable to both sides to move the variable to one side.

7x+9= 3x+29

-3x      -3x

Now, subtract 9 to both sides.

4x+9= 29

    -9   -9

Finally, divide by 4 to both sides to isolate the variable.

<u>4x</u>= <u>20</u>

4     4

x=5

Which exponential function is represented by the graph?
Anna [14]

Answer:

Step-by-step explanation:

Let's solve this using our formula for exponential functions:

y=a(b)^x where a is the initial value and b is the growth/decay rate. We will fill that equation in with 2 of the coordinates on the graph and come up with the values for both a and b. (0, 3) and (1, 6):

3=a(b)^0. Anything raised to the power of 0 is 1, so that means that

a = 3. We will use that value along with the x and y from the second coordinate to solve for b:

6=3(b)^1. b to the first is just b, so our equation is

6 = 3b and

b = 2.

Our equation then is

y=3(2)^x, the third choice down.
