Hey there!

Since we know that x = 5, we first multiply 5 and 5 . . .

5 * 5 = 25

3 * 5 = 15

25 + 15 = 40 <----

The correct answer is 40.

5x + 3x = 40.

Hope this helps you.
Have a great day!

Hi there again!

Since x = 5, we also plug this into the equation.

5x + 3x
= 5*5 + 3*5
= 25 + 15
= 40

So, the answer is 40.

Hope this helps!

For the following exercises, find a formula for an exponential function that passes through the two points given. (0,6) and (3,7
kirill [66]

\boxed{\boxed{f(x)=6(5)^x}}

<h2>Explanation:</h2>

An exponential function is given by the following form:

y=ab^x \\ \\ Where: \\ \\ a \ is \ a \ constant \ and \ b \ is \ the \ base

Here we know two points:

(0,6) \ and \ (3,750)

\bullet \ (0,6) \\ \\ x=0, \ y=6 \\ \\ 6=ab^0 \\ \\ \boxed{a=6} \\ \\\ \\ \bullet \ (3,750) \\ \\ x=3, \ y=750 \\ \\ 750=6b^3 \\ \\ b^3=\frac{750}{6} \\ \\ b=\sqrt[3]{125} \\ \\ \boxed{b=5}

Finally, our exponential function is:

\boxed{\boxed{f(x)=6(5)^x}}
