Use substitution and substitute y into the other equation. One of the equations already gives you y in terms of x, so use that and substitute it into the other equation. y = 3x - 4
Plug into the other equation: -3y = -9x + 12
-3(3x-4) = -9x + 12
-9x + 12 = -9x + 12
This is an identity. So that means that any value of x makes this equation true. So B.
3.4+0.4+4.17=7.97 you just have to try different combinations of different numbers with the decimals.
Answer:
y=14
Step-by-step explanation:
plug in -2 in the place of x
y=-7(-2) y=14
a parallelogram has four sides so all its angles add up to make 360
the angle across from the 55 would also be a 55 equaling a 110 degrees angle leaving you with 250 so your other two angles both equal 125
A line segment is defined as the set of numbers that is contained in a line between the two endpoints.
