Which equation is a linear function?
y=2^x -1
y=x/2-5
y=2/x +3
y=x^2 +7

Second Choice.

Step-by-step explanation:

That is the linear function. Any coefficients with higher degrees won't be considered as a linear function.

So we can cut out the first and last choice.

Then we have only two choices which are

The second equation is called Rational Function where a variable is a denominator.

Therefore, the correct answer is second choice.

1. 2

2. 11

3. 5

4. 6

5. 7

6. 5

7. -1

8. 1

step-by-step explanation:

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
