Answer:
y = -2x + 3
Step-by-step explanation:
5 x -2 + 3 = -7
3 x -2 + 3 = -7
9 x -2 + 3 = 1
-3 x -2 + 3 = 9
You just have to test all of the options, everything, out and pick what fits.
Hope that helps!
Let x be the width
width = x
Length is twice its width
length = 2x
Perimeter = length + width + length + width
Perimeter = x + 2x + x + 2x = 6x
Given that perimeter = 7 1/3
6x = 7 1/3
x = 7 1/3 ÷ 6 = 1 2/9
So width = 1 2/9
Length = 1 2/9 x 2 = 2 4/9
Area = length x width
Area = 1 2/9 x 2 4/9
Area = 2 80/81 square cm
Answer:
3/4
Step-by-step explanation:
1/4 = 0.25 1/2 = 0.50
0.25 + 0.50 = 0.75
0.75= 3/4
(cell tower)/((45 +3) m) = (2 m)/(3 m)
(cell tower) = (48 m)(2/3) = 32 m
B. 32 m . . . . . is the appropriate selection
Answer:
x = -5
y = -5
Step-by-step explanation:
-8y+9x = -5; 8y+7x = -75
Add the two equations together to eliminate y
-8y+9x = -5
8y+7x = -75
----------------------
0y + 16x = -80
Divide each side by 16
16x/16 = -80/16
x = -5
Now find y
8y+7x = -75
8y+7(-5) = -75
8y-35 = -75
Add 35 to each side
8y = -40
Divide by 8
8y/8 = -40/8
y = -5
