Answer:
y=3-3/4x
Step-by-step explanation:
3x+4y=12
-3x -3x
4y=12-3x
/4 /4
y=3-3/4x
Answer
The last one
y+2=-(x+8)
Answer:
y = 8 · 10ˣ
Step-by-step explanation:
y = abˣ
When x = 0, y = 8.
8 = ab⁰
8 = a
When x = 3, y = 8000.
8000 = 8b³
1000 = b³
10 = b
The function is:
y = 8 · 10ˣ
Since the question is asking how fast he is driving, we need to find his speed in miles per hour. To do this, you need to divide the amount of miles he drove by the amount of hours it took. When you do 412.5/7.5, you get the answer of 55 miles per hour.
Answer:
Number of Trucks = 17
Step-by-step explanation:
Given:
Total number of cars and truck = 43
Find:
Number of Trucks
Computation:
Assume
Number of Trucks = x
Number of Cars = 2x - 8
Total number of cars and truck = Number of Trucks + Number of Cars
43 = x + 2x - 8
51 = 3x
x = 17
Number of Trucks = 17
