Answer:
Distributive Property
Step-by-step explanation:
They distributed the -3 to x and 4. In this case, to distribute the -3, you multiply it to each term.
-3 × x = -3x.
-3 × 4 = -12.
-3x - 12
X(x-7)=0
⇔x=0 or x-7=0
⇔x=0 or x=7
(-1,1) is the answer of the slope
Answer:
x=-7, y=-9. (-7, -9).
Step-by-step explanation:
-3x+4y=-15
4x-y=-19
---------------
y=4x-(-19)
y=4x+19
-3x+4(4x+19)=-15
-3x+16x+76=-15
13x=-15-76
13x=-91
x=-91/13
x=-7
4(-7)-y=-19
-28-y=-19
y=-28-(-19)
y=-28+19
y=-9
