Answer:
False.
These are not simultaneous equations.
Step-by-step explanation:
Simultaneous equations are equations involving two or more unknowns that are to have the same values in each equation. In the equations given there is only one unknown value.
Answer:x=5 and x=-5
Step-by-step explanation:
Answer:
y=-2x+3
Step-by-step explanation:
y=mx+b is the equation we want to use. m is the slope, and b is the y intercept. The y intercept is the value that y has when x is 0, which in this case is 3 as is given by the example coordinate.
y=-2x+3

1.2x-1.8=0.2x+1.2
+1.8 +1.8
1.2x=0.2x+3

1.2x=0.2x+3
-0.2x -0.2x
x=3
Answer:
50*0.1=5
Step-by-step explanation:
So 90% off of 50 looks like 50-90%. 50-90%=50*1-0.9*50 since 90% is 9/10 and we are doing 90 percent off of 50. 50*1-0.9*50=50*0.1=5. So $5.
