-4(3)=-12
-4(6)=-24
-12+(-24)=-36
7x - 9 < 12
7x < 12 + 9
7x < 21
x < 21/7
x < 3
1/4x + 8 > 11
1/4x > 11 - 8
1/4x > 3
x > 3 * 4
x > 12
solution : x < 3 or x > 12
Answer:
Step-by-step explanation:
The slope is 3/2
the y-intercept is -4.5
so the equation is y = 3/2x + (-4.5)
(it’s a plus because the slope is positiv, meaning the line goes upwards to the right.)

Answer:
The length of the parallelogram is 18 meters
The width of the parallelogram is 16 meters
Step-by-step explanation:
The perimeter of a parallelogram is 68 meters
LEt x be the length of the parallelogram
Width is 2 meters less than its length
Width =x-2
Perimeter of parallelogram = 2(length + width)
Perimeter of parallelogram =
=
Add 2 on both sides
Divide by 4 on both sides
x=18
The length of the parallelogram is 18 meters
The width of the parallelogram is 18-2= 16 meters
