the first one ((x+8, y+2), r x-axis)
15% of 400 = x
.15 x 400 = x
X = 60 (tip)
400 + 60 = 460
This is an EQUATION, because it has a left side, a right side, and an = sign separating the two.
An EXPRESSION does not has "sides" and no = sign.
Look at the first line: y = (3/5)x - 3. What happens if you multiply each term by 5, to eliminate the fraction?
5y = 3x - 3
Compare this to the second equation,
5y - 3x = -10, or 5y = 3x - 10.
The coefficients of x and y (as 3 and 5 here) determine the slope of a straight line. Since 5y = 3x is present in both equations, the two lines MUST be parallel.
y = 4
4y = 6 => y = 6/4
y+4 and y =3/2 are both horizontal lines. Since they are horiz., they are parallel.
The middle term of the simplified product is “x”.
The simplified product is x^2 - x - 12
X being the middle
hope this helps !
