Analyze the following situations that represent a relationship between x and y. Which situations can be modeled by the equation
SCORPION-xisa [38]

Answer:

I think it's A and D

Step-by-step explanation:

For option A, y would be the height or total growth, and x would be time or months and total height = 0.23 feet × 7.5 months

for option D, y would be the total amount of money spent and x would be the number of granola bars bought.  total money spent = $0.23 × number of granola bars bought

Options B and C don't work because we don't know the initial values and an initial value would be represented in the equation.

In option E, 0.23 represents the total growth in 7 days, so it would be the total instead of the rate of change

JulijaS [17]

Answer:

x² - 3x - 10 = (x - 5) (x + 2)

x² - 6x + 3x - 18

x(x - 6) + 3(x - 6)
