Answer:
A. 3/13
Step-by-step explanation:
The slope formula is ...
m = (y2 -y1)/(x2 -x1)
Using the given points, this is ...
m = (-4 -(-1))/(-8 -5) = -3/-13 = 3/13
I think the answer may be 11
Since the roof has four sides, multiply 63 by 2
63 * 2 = 126
126 + 2x = 216
2x = 90
x = 45
The width is 45 inches
Since there is no question I do not know what is being solved for, but if you’re wondering what the value of x and y equal here’s the explanation.
Set up both equations equal to each other > -2x-4 = 3x+3
Subtract 3 from both sides to get > -2x-7 =3x
Subtract the -2x on both sides to get > -7 = 5x.
Divide both sides by 5 and x = -1.40 or (-1 2/5)
In order to get y value take one of the equation and replace the x in the equation with the value of x you just solved for.
y = -2(-1.4) - 4
multiply the number in the parenthesis and the -2 and you get > y = 2.8 - 4
subtract the two and y = 1.2
x = -1.4 (-1 2/5)
y = 1.2 (1 1/5)
