Answer:
B
Step-by-step explanation:
✔️Rate of change using two points on the line, say (2, 60) and (3, 75);
Rate of change (m) = ∆y\/∆x = (75 - 60) / (3 - 2) = 15/1
Rate of change = 15
This means each class costs $15
✔️Initial value is the y-intercept (b). It represents the initial start-up fee.
To find initial value/y-intercept (b), substitute m = 15 and (x, y) = (2, 60) into y = mx + b.
Thus:
60 = 15(2) + b
60 = 30 + b
60 - 30 = b
30 = b
b = 30
Therefore, initial start-up fee is $30.
Answer:
x = 70
Step-by-step explanation:
Step 1: Simplify both sides of the equations.
Step 2: Subtract 5/7x from both sides.
Step 3: Multiply both sides by 70/(-43).
Step 4: Check if solution is correct.
Therefore, x = 70.
The answer is (-1,-7) because you are pluging it in -1 is x and -7 is y. so 7×-1=-7 and 5×-7 = -35 so -7 minus -35 =28
65/100 = 13/20
(divide by 5 on both sides)
Hope this helped!
