Answer:
x = 3/4
y = 5/4
Step-by-step explanation:
Step:
Substitute−x+2 for y in y=3x−1:
y=3x−1
−x+2=3x−1
−x+2+−3x=3x−1+−3x(Add -3x to both sides)
−4x+2=−1
−4x+2+−2=−1+−2 (Add -2 to both sides)
-4x = -3
x=3/4
Step: Substitute x into the original equation
y=-3/4 + 2
y=5/4
Hope this helps!!
Answer:
D
Step-by-step explanation:
Let's find unit rate of each (number of miles traveled in 1 hour). For that we will divide the distance by time to get the unit rate.
Note: 
(A)
rate = 
mph (miles per hour)
(B)
rate = 
mph
(C)
rate = 
mph
(D)
rate = 
mph
<u>As we can see, the first 3 rates are same, 75 mph, and the last one is 
mph. So clearly, the last rate is the slowest.</u>
D is the right answer.
Answer:
A = x^2 + 4x -21
Step-by-step explanation:
L = x+7
W = x-3
A = L*W
A = (x+7)(x-3)
A = x^2 + 4x - 21
Answer:
Step-by-step explanation:
Disagree, it is not always correct
Consider dividing 5 by 0.5, you get 10 which is greater than what you started with
Solving for B = 0
Then We have A which is = 81 ^b
