Step-by-step explanation:
The answer id D, ^3 sqrt x^9 times x
21.95×.2=4.39
21.95-4.39=17.56
the discount is $4.39
and the total sale price is $17.56

I think this is a high school problem in in 5th grade TnT
Answer:
(5, 6)
Step-by-step explanation:
First, get both equations into slope-intercept form so they are easier to graph:

The first equation is already in this form, so only do the second equation:

To do this, just solve for y and that should almost always get it in the correct form.

That equation is also now in slope-intercept form.
Now, using the slope and y-intercept in both equations, you can graph them. Using the graph, you can see the solution of this system of equations at (5, 6).
Answer:
D. 16.7%
Step-by-step explanation:
Rate of return is:
R = (Vf - Vi) / Vi
R is the rate of return, Vf is the final value, and Vi is the initial value. Essentially, you're finding the change in value and dividing by the initial value.
R = (1750 - 1500) / 1500 = 0.167 = 16.7%
Make sure that you divide by the initial value, not the final. If you divided by 1750 instead, you would have gotten 14.3% which is not correct.
Make sure you check your sign as well. The value increased, so the rate of return is positive.
