Answer:
total cost = cost/hour x hours
$18.00 = ($4.50)(X hours)
X=4 hours
Step-by-step explanation:
total cost = cost/hour x hours
$18.00 / 4.50=4 hours
Answer:
3
Step-by-step explanation:
Answer:
y=x+1
Step-by-step explanation:
first find the slope using the two coordinates:
use the slope formula- m=y^2-y^1/x^2-x^1
6-2/5-1
=4/4
=1
y=mx+b
now plug in one of the coordinates, and the slope we just found into the slope intercept formula
2=1(1)+b
2=1+b
subtract 1 from both sides
1=b
1=b; m=1,
y=x+1
Answer:
= -x^2 -x +6
D: all real values
Step-by-step explanation:
f(x) = 4-x^2
g(x) = 2-x
f+g = 4-x^2+ 2-x
Combine like terms
= -x^2 -x +4+2
= -x^2 -x +6
The domain is what values can x take
D: all real values
