I remember CUP -- concave up positive. Here we have a leading coefficient that's negative, so the cup is upside down, the parabola opens down, an arch not a bowl.
6y + 12 = 3y - 3
Subtract 3y on both sides
3y + 12 = -3
Subtract 12 on both sides
3y = -15
Divide by 3 on both sides
y = -5
so you have your two equations 3x+7=5x-23 and solve for x which is your "number" leaving the answer to be <u>x=15</u>
The equation with (x) in dogs and (y) in dollars is
First, you must set up your equation.
Then, you must add like terms to simplify the equation
TRUE because 8/15 = 0.53 which is less than 3/5 = 0.60
