Make sure and use distributive property on the ones multiplying by what’s in the parentheses
The answer is A) x = 9
We know this because every four sided figure has angles that measure up to 360. So we can subtract all of the angles and then use the remaining angle to solve the problem.
360 - 90 - 90 - 99 = 81.
So with the remaining angle being 81, we can solve for x.
x^2 = 81
x = +/-9
Since +9 is the only answer that makes sense in this case, x = 9.
F(1) = -2

---------------------------------
We know that the opposite angles are equal
So...
3y - 20 = 2x + 6 and 4x = 4y + 4
That is the system of equations you need to solve
Answer:
x = 3 and y = -18
Step-by-step explanation:
y = -6x
y = -8x + 6
Both equations are equal to y. So,
y = -6x = -8x + 6
Solve for x first.
-6x = -8x + 6
Add 8x to both sides.
2x = 6
x = 3
Substitute x = 3 into y = -6x
y = -6 * 3
y = -18
Now, double check to see if this is correct.
y = -8x + 6
-18 = -8 * 3 + 6
-18 = -24 + 6
-18 = -18
x = 3 and y = -18 are correct.
