∆= 180°
180°-(62°+58°)= ?
180°-120°=60°
a line = 180° on both sides.
180°-60°=X
120°=X
We can take the two points given and plug them into the slope formula.
(-3, 3), (1, -5)
x1 y1 x2 y2

Answer:
-0.9, -0.85, -3/4, -1/2, 1/4, 0.55
Step-by-step explanation:
Plug in 6.5 for x.
-8.5x-3.5x=-78
-8.5(6.5)-3.5(6.5)=-78
-55.25-22.75=-78
-78=-78
Answer:
no, because for x=-3, y would have to be -31
Step-by-step explanation:
boy oh boy (or girl oh girl) - you wrote this in a horrible, horrible format.
I can only guess what your problem and the fitting answer would be.
y = -2×x^2 + 3×x - 4
-4 = -2×(-3)^2 + 3×(-3) - 4
-4 = -2×9 - 9 - 4
-4 = -18 - 9 - 4
-4 = -31
and that is wrong. for (-3,-4) to be on the graph of the function, y would have to be -4 when using x=-3 in the function. but y = -31 for x= -3.
