Answer:

40

Step-by-step explanation:

9a + 9b + 9c = 5

We want 72a

72a/9a = 8  so multiply the first equation by 8

8(9a + 9b + 9c) = 5*8

72a +72b +72c = 40

Answer:

40

Step-by-step explanation:

Divide all three terms of 72a + 72b + 72c by 8.  Result:  8(9a + 9b + 9c).

We are told that 9a + 9b + 9c = 5.    Thus, 8(9a + 9b + 9c) = 8(5) = 40

Solve the inequality for x. Show each step of the solution. 10x>8(3x-2)-12
Anettt [7]

Answer:

x < 2

Step-by-step explanation:

Given

10x > 8(3x - 2) - 12 ← distribute parenthesis on right side

10x > 24x - 16 - 12, that is

10x > 24x - 28 ( subtract 24x from both sides )

- 14x > - 28

Divide both sides by - 14, reversing the inequality symbol as a result of dividing by a negative quantity.

x < 2

What is the axis of symmetry for f(x) = 2x2 − 4x + 5? (1 point) x = −2 x = −1 x = 1 x = 2
Gnom [1K]

Answer:

y = 2x^2 − 4x + 5

y = 2(x^2 − 2x) + 5

y = 2(x^2 − 2x + 1 - 1) + 5

y = 2(x^2 − 2x + 1) + 5 - 2

y = 2(x - 1)^2 + 3

x = 1 is the axis of symmetry.

Do you agree?
