Answer:
The faster train goes 60mph
Step-by-step explanation:
s= speed
s+20 is the faster train.
Then you are given:
200/s+s+20=2
200=2*(2s+20)
4s+40=200
4s=160
s=40 is the slower train
40+20= speed of faster one
s=60 ;)
Answer:
See answers below
Step-by-step explanation:
From the given functions, the equivalent function for when x = 0 is -(x-1)²
h(x) = -(x-1)²
h(0) = -(0-1)²
h(0)= -(-1)²
h(0) = -1
when x = 2, the equivalent function is -1/2x - 1
h(x) = -1/2x - 1
h(2) = -1/2(2) - 1
h(2) = -1-1
h(2) = -2
when x = 5, the equivalent function is -1/2x - 1
h(x) = -1/2x - 1
h(5) = -1/2(5) - 1
h(5) = -5/2-1
h(5) = -7/2
Answer:
P=l+w
Step-by-step explanation:
Solve for P by simplifying both sides of the equation, then isolating the variable.
Answer:
When you distribute the 7 to each set you get 14-21n and 14-21n
Step-by-step explanation:
Answer:
X = -3
Step-by-step explanation:
X/2-5 = 1
X/-3 = 1
Multiply both sides by -3 to isolate x
X = -3
