Answer:
y = 3x +6
Step-by-step explanation:
6x-2y=-12
Slope intercept form is y = mx+b where m is the slope and b is the y intercept
Subtract 6x from each side
6x-6x-2y=-6x-12
-2y = -6x-12
Divide each side by -2
-2y/-2 = -6x/-2 -12/-2
y = 3x +6
Answer:
length = 11 , width = 18
Step-by-step explanation:
Begin by letting x represent the width.
then double the width = 2x and 5 less than this = 2x-5
meaning the length is 2x - 5
now perimeter = 2x width + 2 x length
therefore 2x + 2(2x - 5) = 38
so 2x + 4x - 10 = 38
⇒ 6l = 38 + 10 = 48 ⇒ l = 8
width = x = 8cm and length = 2x - 5 = 16 - 5 = 11cm
check check: (
2 x 8
) + (
2 x 11
) = 16 + 22 = 38
