Question: What is the Question?
Answer:
y=-1/3x
Step-by-step explanation:
We use the linear equation of y=mx+c
Y=c
We know that y=0 and that m=-1/3, therefore we plug it in the formula.
y=-1/3x+0
y=-1/3x
8x - 4 is an expression. This means that x can mean anything.
If you mean 8*-4, the answer would be -32 because 8 multiplied by 4 is 32, but since a positive multiplied by a negative equals a negative, the product would become a negative.
x/3=x^2/x+5
First cross multiply to get rid of the fractions.
x^2+5x=3x^2
Simplify by combining like terms.
-2x^2+5x=0
Factor out x.
x(-2x+5)=0
One of the factors must equal zero for the equation to stand.
x=0,2.5
Check for extraneous solutions by plugging in the values for x. They both work.
