Answer:
x = 
Step-by-step explanation:
We know that p(x) = 13. Thus, substitute 13 for the "p(x)" in the equation. Then, isolate x by subtracting both sides by 
:
Thus, x = .
You would want to round to the nearest $1 so that the total would be more accurate.
-7(x-4) = 63. Divide each side by -7.
x - 4 = -9. Add 4 to each side.
x = -5
Answer:
-i
Step-by-step explanation:
i^15
Divide the exponent by 4
15/4 = 3 r 3
Take the remainder and use as the exponent
i^3
We know that i^2 = -1
i^3 = i^2 *i
i^3 = -1*i
-i
So, 30% is 0.30, but since you are taking off 30%, you are going to have 70% of the price which is 0.70. The word "of" lets you know that you are going to multiply. So, what you do is 150•0.70=105. The discounted price is $105
