Answer:
a=1/2
Step-by-step explanation:
6-7(a+1)=-3(2-a)
6-7a-7=-6+3a
5=10a
a=1/2
Answer:
D
Step-by-step explanation:
A line with a positive slope goes upwards from left to right.
A line with a negative slope goes downwards from left to right.
The given lines are all in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 5 has m = 2 ← positive
y = 2x - 6 has m = 2 ← positive
y = 2x has m = 2 ← positive
y = - 2x + 20 has m = - 2 ← negative
Thus y = - 2x + 20 goes downwards from left to right
It would be at rate of 68 ill use per minute so
68x=1y
I’m going with 26 units apart
