Answer:
y = 4x + 4
Step-by-step explanation:
If this equation is parallel to y = 4x + 2, that means it would have the same gradient. And since the y-intercept is stated, you just need to put it next to the gradient
Answer:
Step-by-step explanation:
(6x-3)=(4x+33)
Combine like terms,
Subtract 4x on both sides and add 3 to both sides
2x=36
Divide by 2 on both sides
X=18
Answer:
a = 3
Step-by-step explanation:
The triangles are similar, so the ratio of short side to long side is the same for each:
(a +5)/12 = 12/18
a +5 = 12(12/18) = 8 . . . . . multiply by 12
a = 3 . . . . . . subtract 5
