Answer:
evaluate the function with -3 as x value
Step-by-step explanation:
4(-3) + 5
-12 + 5
= -7
$417.50 should be the correct answer you just multiply the $7.25 to 30 and then add the $200.
Answer:
Each jump rope will cost: $15.28 ÷ 4 = $3.82
Given the function f(x)=x^2+5x+5 , to get the zeros we solve using quadratic formula;
x=[-b(+or-) sqrt(b^2-4ac)]/(2a)
from our function;
a=1,b=5, c=5
thus,
x=[-5(+or-)sqrt(5^2-4*1*5)]/(2*1)
x=[-5(+or-)sqrt(25-20)]/2
x=[-5+/-sqrt(5)/2
The answer is option C
