Step-by-step explanation:
Answer:
5.7x
Step-by-step explanation:
Addition, 4.2x+1.5x=5.7x
Answer:
12
Step-by-step explanation:
Since they are parallel then
(7x - 8) + (11x - 28) = 180
18x - 36 = 180
18x = 216
x = 12
4y=3x-24
y=3/4x-6
the line intersect x axis in A
y=0, 3/4x=6, 3x=24, x=8 ⇒ A (8,0)
the line intersect y axis in B
x=0, y=-6 ⇒ B (0,- 6)
a.the gradient of l is 3/4
b. AB= V 6^2 +8^2=V36+64=V100=10
