When an exponent is equal to 0, the whole expression equals one. It does not matter what the base is - the expression will always equal 1. When the exponent is negative, the expression equals 1 over the expression. Here are some examples where this might be useful:

<h2>x^{0} = 1</h2><h2>x^{-4} = \frac{1}{x^4}</h2>

Hope you found this helpful!

DedPeter [7]

Answer:

Gross yearly pay = $25,200

Benefits = $7,560

Total value = $25,200 + $7,560 = $32,760.

Step-by-step explanation:

We know that she will be paid $10.50 an hour. Assuming she works 40 hours per week, that amounts to $420. Multiply that by 60 weeks a year and we get $25,200.

To find the benefits, you simply multiply $25,200 by 0.30 to get $7,560.

Then, the total value is found by just adding the two numbers together as such.

Here’s a graph of a linear function. Write the equation that describes that function.
lord [1]

Answer:

y = 5x - 5

Step-by-step explanation:

It appears that the graph intersects the y-axis at (0, -5).  This point is the y-intercept of the line.

As we move from (0, -5) to the point (2, 5), x increases by 2 and y increases by 10.  Thus, the slope of the line through these two points is

m = rise / run = 10 / 2  = 5.

The slope-intercept form of the equation of a straight line, y = mx + b, becomes y = 5x - 5
