The answer is 20
Step-by-step explanation:
It will just be -7/12 because anything times 1 stays the same
Answer:
Step-by-step explanation:
Move 3k to left hand side and change it's sign
Similarly, move 4.5 to right hand side and change it's sign
Collect like terms
Subtract 4.5 from 18
Divide both sides by 4.5
Calculate

Best to find the equation of the parabola first:
Its equation is y+12.5 = (x+1.5)^2, or y = -12.5 + (x+1.5)^2
Check the first possible x-intercept: let x = -2. Does y come out to 0?
y = -12.5 + (-0.5)^2 = -12.5 + 0.25. This is not equal to 0, so (-2,0) is not an x-intercept of this parabola. Continue checking each possible x-intercept until you find the right one (or ones).
