12.8 / 8 = 1.6
8 / 5 = 1.6
SF = 1.6
so x = 6 * 1.6 = 9.6
answer
x = 9.6
Answer:
10m
Step-by-step explanation:
Recall that the perimeter of a rectangle
= (2 x Long Side) + (2 x Short Side)
we are given that each of the long side = 20m and the perimeter is 60m
substituting these into the equation,
60 = (2 x 20) + (2 x Short Side)
60 = 40 + (2 x Short Side) (subtract 40 from both sides)
60-40 = (2 x Short Side)
(2 x Short Side) = 20 (divide both sides by 2)
Short Side = 20 / 2 = 10m
Answer:
(x, y) = (-2, 7), (0, -1), (3, -13), (-1, 3)
Step-by-step explanation:
To fill in the y-values, you need to put the x-value in the equation and evaluate.
<u>for x=0</u>
y = -4(0) -1 = -1
<u>for x=-1</u>
y = -4(-1) -1 = 4 -1 = 3
__
To fill in the x-values, we can solve for x and then do as we did above.
y = -4x -1
y +1 = -4x . . . . add 1
-(y +1)/4 = x . . . divide by -4
<u>for y=7</u>
x = -(7 +1)/4 = -2
<u>for y=-13</u>
x = -(-13+1)/4 = -(-12/4) = 3
__
Then the table is ...
Answer:
y = 3x + 8
Step-by-step explanation:
<span>two sides of the rectangle will extend FROM the wall of the house, one side of the rectangle will run PARALLEL to the house (40 ft) </span>
<span>2x + 40 = 150 </span>
<span>or </span>
<span>x + x + 40 = 150 </span>
