You have to plug in the parking rates in the chart into the equation where it has x.
The answer is B. $3.85.
This is because, first if we get the percentage that the shoes were marked up by, we get that they were marked up to $35, because 40% of $25 is $10 and $25 + $10 = $35.
Then, we find the percentage of $35 that she earned. In order to do this, we see what 11% of $35 is. We get $3.85, because 10% of $35 is $3.50, and 1% of $35 is $0.35. $3.50 + $0.35 = $3.85.
This is why the answer is B. $3.85.
Answer:
To find to polynomial from zeros.
Find the factors. If it is a positive zero, the factor will be (x- zero) If it is a negative zero if is (x+zero)
Multiply the factors together.
Zeros of -4, -2, 5 would be:
Find the factors: (x+4)(x+2)(x-5)
Multiply the factors together: Will start out with FOIL for (x+4)(x+2) = x2+2x+4x+8 Combine like terms. Then multiply by the last factor
(x2+6x+8)(x-5) using the distributive property
x3+6x2+8x-5x2-30x-40 Combine like terms
x3+x2-22x-40
For the next one, the factors are a bit more complicated because of the radical. With a radical, you will also have to have a factor with the conjugate (Same term opposite sign)
4, 6, negative square root of 7
Factors would be: (x-4)(x-6)(x-√7)(x+√7) You can FOIL the first 2 factors and the last 2, then multiply them together using the distributive property.
Step-by-step explanation:
hope this helps!!!!
-2(x + 6) + 3 = -11x + 4(x + 4)
-2x - 12 + 3 = -11x + 4x + 16
-2x - 9 = -7x + 16
5x = 25
<em>x = 5</em>
Hope this helps! :)
