Answer:
15) 37 16) -5x+13=-112, x=25 23) l=38, w=19
Step-by-step explanation:
15) l=5w+2, 2l+2w=88
2(5w+2)+2w=88
12w+4=88
w=7, l=37
16a) -5x+13=-112
16b) x=25
23) l=2w, 2l+2w=114
2l+l=114
l=38, w=19
<u>Slope-Intercept:</u>
y + 3 = 6(x + 2) - 3
y + 3 = 6x + 12 - 3
<u> -3 </u> <u> -3 </u>
y = 6x + 12
<u>Standard:</u>
y = 6x + 12
<u>-6x </u> <u>-6x </u>
-6x + y = 12
-1(-6x + y = 12)
6x - y = -12
<u>Graph:</u>
y = 6x + 12

Start by graphing the y-intercept: (0, 12)
Then count the rise (up 6) and the run (right 1) from the y-intercept: (1, 18)
or
count the rise (down 6) and the run (left 1) from the y-intercept: (-1, 6)
Answer: (x-6)(x+1)
Step-by-step explanation:
Sum : x2 − 5 x- 6
x2 + x-=6 x − 6
factor pair: x 2 + x − 6 x − 6
x( x+ 1 ) − 6 ( x + 1 )
rewrite from: x (x + 1 ) − 6 ( x + 1 )
(x-6)(x+1)
Answer:
3x+2y=2x+8
3x-2x+2y=8
3x-2x=8-2y
x=8-2y
