Answer:
D. -1.2(3x-40)
Step-by-step explanation:
Multiply -1.2 x 3x and -1.2 x -40.
-1.2 x 3x= -3.6x
-1.2 x -40= 48 (two negatives cancel each other out, so it will be +48)
= -3.6 +48.
You can also automatically eliminate B. and C. because multiplying the -4 within the perenthesis would not give you 48.
A. says (3x + 40), which would give us a negative 48.
Answer:
y = 15 hour - 3 hours/day x days
y = 15 - 3x
y-intercept = 15 - 3(0)= 15 which is the amount of volunteer hours she must complete at day 0.
0 = 15 - 3x
3x = 15
x = 5 (Number of days she would have to volunteer)
Equation: y = 15- 3x

Answer:
-15 and -2
Step-by-step explanation:
Since a negative times a negative equals a positive, but when added, still stays a negative, the factors must both be negative.
Negative Factors of 30:
-30 + -1 = -31
-15 + -2 = -17
-10 + -3 = -13
-6 + -5 = -11
The two factors of 30 that add up to -17 are -15 and -2.
Hope this helps. Have a nice day.
