WHY ARE THESE QUESTIONS SO HARD FOR ME I SWEAR TO GOD I- BRAINLIEST!!

Which is the equation of the parabola?

a. y = −one eighth(x + 3)2 + 2
b. y = one eighth(x − 3)2 − 2
c. y = one eighth(x + 2)2 + 3
d. y = −one eighth(x − 2)2 − 3

Karianne and lucius are analyzing a linear function on a graph. karianne says that unit rate is equal to rate of change, but that slope is calculated differently. lucius says that unit rate, rate of change, and slope are calculated the same way. who is correct? explain your answer.

Mr switzer needs to buy new 1-foot tiles to cover his bathroom floor. the floor is 12 feet long and 8 feet wide. each square foot of tile will cost $1.79. in dollars what will be the total cost of the tiles he needs to buy.

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
