Answer:
y = -3x + 9 is your answer.
Step-by-step explanation:
So your y-intercept is the slope. Here is the equation we are going to use:
y - y_1 = m(x - x_1)
y_1 = 0
x_1 = 3
m = -3.
y - 0 = -3(x - 3)
y - 0 = -3x + 9
Rate of change = 0.5
Initial value = 120
(10 , 125) ; (30 , 135)
Slope =
(x+1)^2-x^2=23
x^2+2x+1-x^2=23
2x+1=23
2x=22
x=11
11^2 = 121
x+1 =12
12^2=144
144-121 = 23

Option A
2x^2+10x+12
Divide through by 2
x^2 +5x+6=0
x^2 +3x+2x+6
x(x+3)+2(x+3)=0
(x+2)(x+3)=o
x=-2 or x=-3
