Answer:
x=5
Step-by-step explanation:
28x+20y =14*4 = 56
28x + 21y = 9*7 =56
=> y=0, x = 2
If its parallel then angular coeficient is the same
y = 5x + 3
The other line m = 5
(y - yo) = m.(x - xo)
(y - 7) = 5.(x - 9)
y - 7 = 5x - 45
y = 5x - 45 + 7
y = 5x - 38
Alternative D
Since three fourths is equal to .75 we should be able to do .75/24 which equals .03125 if I'm not mistaken
