Answer: 4( x - 5)( x - 2)
Step-by-step explanation:
4x^2 -28x + 40
4 ( x - 5)(x - 2)
Answer:

if u substitute the givens in the eqn we will get..

then collect like terms


Answer:
First turn 3x + y = -5 to slope-intercept form (y=mx+b) by subtracting 3x in order to move it to the other side, to get
y = -3x - 5.
So now you have all three lines in proper slope-intercept form. (Don't worry about
y = 7 - 3x, it's still in slope-intercept form, despite the y-intercept and slope being swapped.)
<u>Here are the lines rewritten below</u>.⤵⤵⤵
1. y = -3x - 5
2. y = -3x + 7 or y = 7 - 3x (either way works)
3. y = -3x + 2.5
As we can see, all three lines are parallel.
Because all the slopes are the same and the y-intercepts are different. If the slopes were different, the lines wouldn't be parallel.
I also graphed the lines above, so you can see what I mean.⤴⤴⤴ Hope this helped :)
The correct graph is the third one, with the solid dots at -3 and 3.
The bars around x stand for absolute value, which is defined as the distance a number is from 0. We want to know what number or numbers is/are 3 units away from 0 on a number line; the only choices are 3 or -3.
This means we must plot points at -3 and 3. They must be solid points, since these numbers are included in the solution (they are, in fact, the only ones of the solution).
