Answer:
There is no graph
Step-by-step explanation:
<span>4x−3y=12
7x−3y=3 Important: you have two -3y terms. Mult one eqn by -1 to
obtain +3y, and then add the 2 equations together:
4x - 3y = 12
-7x+3y = -3
----------------
-3x = 9, so x = -3. Subst. -3 for x in the first original equation to find y:
4(-3) - 3y = 12, or -3y = 24. Then y = -8.
Solution is (-3, -8).
It's important that you check this answer by subst. (-3, -8) back into either one of the original equations.

Answer:
x=69° y=69°
Step-by-step explanation:
Angle x is an alternate angle so it is equal to the angle above it (69)
Angle y is in a co-interior angle so you do the equation 180-111 which equals 69°
Answer:
P'( 4, -4)
Step-by-step explanation:
The double reflection across the x-axis does nothing, so the net effect is a single reflection across the y-axis. That effect is to negate the x-coordinate:
reflection across y-axis: (x, y) ⇒ (-x, y)
Then P(-4, -4) ⇒ P'(4, -4)
Answer:
Step-by-step explanation:
f(x) =2x - 7
f( - 3) = 2( - 3) - 7 = - 13
f(3) = 2(3) - 7 = - 1
f(a) = 2a - 7
- f(a) = - (2a - 7) = 7 - 2a
f(a + h) = 2(a + h) - 7 = 2a + 2h - 7
