Answer:
C)
f(–3) = 9
Step-by-step explanation:
Given f(x) = 4x^4 + 5x^3 – 15x^2 – 45
f(-3) means let x = -3
f(-3) = 4(-3)^4 +5(-3)^3 – 15(-3)^2 – 45
=4(81) +5(-27) -15(9) -45
= 324 - 135 - 135 -45
=9
Answer:
A.
Step-by-step explanation:
Colored dot means ≤ or ≥
Since it is at least, she needs to have that exact amount (equal) or more ( > )
85 - 61 = 24
24 is the least amount she can have
She needs $24 or more
2028/x=100/30
<span>(2028/x)*x=(100/30)*x </span>we multiply both sides of the equation by x
<span>2028=3.3333333333333*x </span>we divide both sides of the equation by (3.3333333333333) to get x
<span>2028/3.3333333333333=x </span>
<span>608.4=x </span>
<span>x=608.4
so there for its 608.4 hope this helps.</span>
The answer is B) (2,-1).If you don’t believe me punch in the coordinates into a graphing calculator and then punch in (2,-1). It will give you a perfect parallelogram.
Considering her change, it is found that she will donate $0.28 to the animal shelter.
<h3>How to find the amount of change in a purchase?</h3>
The amount of change is given by the subtraction of the total paid and the price of the products.
