Answer:
x = 20
Step-by-step explanation:
For the lines to be parallel, the angles have to be equal
2x+15 = 55
Subtract 15 from each side
2x+15-15 = 55-15
2x = 40
2x/2 = 40/2
x = 20
Answer:
John pay:449.65
Step-by-step explanation:
(391×15)÷100=58,65
391+58,65=449,65
We are given with an original equation of y = x where the slope is 1 and passes through (0,0). if the equation is translated by 8 units to the right, the line still has the same slope but now passes through (8,0).
y-y1 = m (x-x1)y - 0 = 1 (x-8)y = x - 8
The line now becomes y = x - 8
What is the question here? It doesn't really make sense the way that it is put
