-4x-8>-20
+8 +8
-4x>-12
Divide by 4 on both sides
x<3
Should be A.
Hope this helps.
Answer:
55%
Step-by-step explanation:

Answer:
x=1 and x=0
Step-by-step explanation:
We need to find the points at which the graphs y = x^2 + x – 2 and y = 2x – 2 intercept.
We know that:
x^2 + x – 2 = 2x – 2
x^2 - x = 0
Factorizing:
x(x-1) = 0
Therefore, the solution to the system of equation is x=1 and x=0.
Answer:
no, 72 km/hr is equal to 20m per sec
