Luca bought his home for $115,000 in 2007. Property values have increased 5% every year since he has owned the home. Which of the following equations can be used to represent the price of the home x years after 2007?

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

step-by-step explanation:

mark brainliest!

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
