Answer:
What?
Step-by-step explanation:
Answer:
x = 11
y = 17
Step-by-step explanation:
We know that opposite angles (or vertical angles) are equal.
So
8x + 7 = 9x - 4
Subtract 8x from both sides of the equation
8x - 8x + 7 = 9x - 8x - 4
7 = x - 4
Add 4 to both sides of the equation
7 + 4 = x - 4 + 4
11 = x
Looking at the other 2 angles,
5y = 7y - 34
Subtract 7 y from both sides of the equation
5y - 7y = 7y - 7y - 34
-2y = -34
Divide both sides by -2
-2y/-2 = -34/-2
y = 17
Answer:
3x - 300
Step-by-step explanation:
Expand the brackets or use distribute law.
Answer:
it's 4
Step-by-step explanation:
take the given point and evaluate the x value in for x, and the y value for y, and simplify. If the equation is true, the point is a solution. if not, then it is not a solution.
12 and -3.
-3 * 12 = -36, and
12 - 3 = 9
There's your answer!
