Answer:
The answer is -6.
Step-by-step explanation:
You have to substitute x = -4 into the expressions :
3x - x + 2
= 3(-4) - (-4) + 2
= -12 + 4 + 2
= -6
Answer:
C. or 3 1/4
Step-by-step explanation:
First, turn all of the amount of fruits (Grapes, Melon, and Pineapple) into an improper fraction.
Grapes: 11/3
Melon: 9/4
Pineapple: 11/4
Then, make a common denominater for each fraction, which is 12, add all of them up. Since you know that the amount of strawberries that Maria uses is 3/8 TIMES the amount of the other fruits, so you multiply the fruits by 3/8.
Grapes: 44/12
Melon: 27/12
Pineapple: 33/12
44/12 + 27/12 + 33/12 times 3/8
= 104/12 times 3/8
= (if you simplify) 13/4 times 1/1 (1/1 = 1)
= 13/4
= 3 1/4
So, the answer is C. 3 1/4

Answer:
2
Step-by-step explanation:
produces a straight line
Answer:
v ≥ -17
Step-by-step explanation:
-82 ≤ 5v + 3
-82 - 3 ≤ 5v
5v ≥ -85
v ≥ -17
Assuming the left is minutes and the right is distance, Mario runs 1 mile in 7 minutes
(a) y=x/7
(b) the rate of change is 7
(c) if he ran for 70 minutes then his distance is 10 miles.
*for (c) just plug in the number given. Replace it with x and divide it by 7.*
