Answer:
x = -2
Step-by-step explanation:
Add 10 to both sides of the equation
x−10=−12
−10+10=−12+10
Simplify
Solution:
x= -2
Answer:
Rate of change: 25
Initial value: 25
Equation: y = 25x + 25
Step-by-step explanation:
✔️hours = x
Fee = y
Rate of change (m) = ∆y/∆x
Rate of change (m) = 25/1 = 25
Rate of change (m) = 25
✔️Initial value = y-intercept (b).
To find the initial value, simply substitute (x, y) = (1, 50) and m = 25 into y = mx + b.
Thus:
50 = (25)(1) + b
50 = 25 + b
Subtract 25 from each side
50 - 25 = b
25 = b
b = 25
✔️To write an equation, substitute m = 25 and b = 25 into y = mx + b.
Thus:
y = 25x + 25
y=2x+3 (the 3 can be changed)
Answer:
1.83 times
Step-by-step explanation:
Take the distance biked divided by the distance run.
2 3/4 / 1.5 = 1.83 times.
This means that Alex biked 1.83 times more than the distance she ran.
