Answer:
D) y = 3x - 9
Step-by-step explanation:
1) 14
2) -10
3) 23
Tell me if you need details
Y=-5x-19
Y=5x +1
Y=-18
-18=5x+1
-19=5x
X= 3.8
Might be wrong
First you foil so you would get
0.5r+1.375=3
Then you subtract the 1.375 to the 3
0.5r=3-1.375
0.5r=2.375
Now to find r you need to divide by 0.5
r=2.375/0.5
(x + 6)(4x + 1)
x times 4x = 4x^2
x times 1 = x
6 times 4x = 24x
6 times 1 = 6
<span>And finally, by adding like terms, 4x^2 + 25x + 6
I hope this helps you! Good luck :)</span>
