Answer:
A
Step-by-step explanation:
f(x) = 2x
f(-4) = 2(-4) = -8
D--because it has y^2 in the equation and to isolate y you have to take the square root, the graph is going to be curved rather than linear.
Answer:
2²
Step-by-step explanation:
The prime factorization is only prime numbers multiplied
4 is 2(2) which is
2²
First, distribute the terms.
1(2x^3) = 2x^3
-1(x^2+11) = -x^2-11
Standard form:
2x^3 - x^2 - 11
Since there is a 3, the degree of polynomial is cubic.
Let x be the entire portion of the money Becca needs to save to buy a new tennis racket.
So, 0.25x=$21
x=$21/0.25
x=$84
Thus, the total amount she needs to save is $84. Now, we'll deduct 25 from 84 to get the 75 percent or the remaining amount she has to save.
$84-$21=$63
The answer is $63.
