First square both sides
1-3x=(x+3)^2 use foil to unfactor it
1-3x=x^2+6x+9 subtract 1 from both sides
-3x=x^2+6x+8 add 3x to both sides
0=x^2+9x+8
Now that we got it equal to zero you have to factor the new trinomial
0=(x+1)(x+8)
Now since both are being multiplied by each other, if you get 1 of them to equal zero then both equal zero since 0 times anything equals 0.
So your solutions are x=-8 and x=-1

Answer:
y=1
Step-by-step explanation:
Start by plugging in -3 for x in the equation 2x+5y=-1 then solve for y.
2(-3)+5y=-1
-6+5y=-1 (add 6 to both sides)
5y=5 (divide both sides by 5)
y=1
Answer:
the answer would be 3 hours
Step-by-step explanation: if she wants to spend $27 then she can only rent for 3 hours because 27 - 15 = 12 and 12 divided by 4 is three.
Inequality: y = 3x -15
Solution is 3 hours
