If two line are perpendicular. The multiply of their slopes are equal to -1.
First line's slope is: -1/2x because if the line equation is form of y=ax+b a is slope.
Let say second line's slope is m
m.-1/2=-1 so m=2
y=ax+b is general form of linear function/equation. (a=slope)
y=2x+b
If this line passes through the point (2,-2),if we write -2 to y and 2 to x, the equation becomes true.
-2=4+b
b=-6
Thus,
y=2x-6 is true answer.
The answer in a fraction is 2/5 , the answer in decimal form is 0.4 !
The length of the parallelogram is 3/4 ft less 1/8 ft, or 6/8 ft less 1/8 ft, or 5/8 ft.
The width is 1/2 ft.
Thus, the area is (5/8 ft)(1/2 ft) = (5/16) ft^2
Answer:
-1.2
Step-by-step explanation:
Answer:
x=3
Step-by-step explanation:
First, combine like terms on the left side
4x-5x+9=5x-9
-x+9=5x-9
Subtract 9 on both sides
-x=5x-18
Subtract 5x on both sides
-6x= -18
Divide by -6 on both sides
x=3
Hope this helps! :)
