Answer:
4(x-3)(x+6)
Step-by-step explanation:
We factor out the 4 first since all numbers are divisible by 4. That leaves us with x^2+3x-18.
Then we factor this to get (x-3)(x+6).
So the factored form of the equation is 4(x-3)(x+6)
13. Answer: n ≥ 108
<u>Step-by-step explanation:</u>
18 ≤ n ÷ 6
<u>×6 </u> <u> ×6 </u>
108 ≤ n → n ≥ 108
Note: The line under the inequality symbol represents a closed dot

14. Answer: x > -4
<u>Step-by-step explanation:</u>
-3x < 12
<u>÷(-3) </u> <u>÷(-3) </u>
x > -4 <em>Flip the inequality sign when × or ÷ by a negative </em>
Note: No line under the inequality symbol represents an open dot

Answer:
YZ=16
Step-by-step explanation:
Because they are parallel
Answer:
a) the same line
Step-by-step explanation:
The first equation is the "slope-intercept form" of the equation of a line with slope -3 and y-intercept +1. The second equation is the "point-slope form" of the equation of <em>the same line</em>. The "point" in this form is (x, y) = (2, -5), which is a point that satisfies the first equation:
y = -3x +1
-5 = -3(2) +1 . . . . true
The two equations represent the same line.
