7 – 4 (3a – 5) I NED HLP ASAP. I WILL TRY BRAINLIEST TO FIRST ANSWER. EXPLANATION ALSO NEEDED

The answer is a = 2.25.

Simplifying

7 + -4(3a + -5) = 0

Reorder the terms:

7 + -4(-5 + 3a) = 0

7 + (-5 * -4 + 3a * -4) = 0

7 + (20 + -12a) = 0

Combine like terms: 7 + 20 = 27

27 + -12a = 0

Solving

27 + -12a = 0

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-27' to each side of the equation.

27 + -27 + -12a = 0 + -27

Combine like terms: 27 + -27 = 0

0 + -12a = 0 + -27

-12a = 0 + -27

Combine like terms: 0 + -27 = -27

-12a = -27

Divide each side by '-12'.

a = 2.25

Simplifying

a = 2.25

the first one, all those points on the line just make a strait line.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
