Answer:
108ft²
Step-by-step explanation:
6×6=36
12×12=144
144-36=108ft for the shaded part
H because it adds up to 46
2x-3y = 13
x + 2y = -4
For this case, the first thing we can do is rewrite the system of equations as:
2x-3y = 13
-2x-4y = 8
We now add both equations obtaining:
-7y = 21
We clear y:
y = 21 / -7
y = -3
We substitute the valos of y = -3 in any of the equations to find x:
x + 2 (-3) = - 4
We clear x:
x-6 = -4
x = -4 + 6
x = 2
Answer:
2x-3y = 13
x + 2y = -4
The solution to the system of equations is:
x = 2
y = -3
Do you have the specific point??
Remember, if 2 lines are perpendicular, their slopes are opposite reciprocals. So if one line has a slope of 4, the other line should have a slope of -1/4.
Hopefully your equation is in y=mx+b form. If so,
make sure you know slope (m) and the y-intercept. After this is done, plug in the points from p for y and x, and make sure to turn m into -1/m. Solve for b, and your new equation should be y=(new slope)x+(new y-intercept)
