Answer: If 2/3x + 2 and 4/3x - 6 had the same value, then x would have the value of 12.

Step-by-step explanation:

2/3x + 2 = 4/3 x - 6 is our equation.

Let's start simplifying!

First, we'll subtract 2/3x from both sides.

2/3x - 2/3x + 2 = 4/3x - 2/3x - 6

2 = 2/3x - 6

Next, we'll add 6 to both sides.

2 + 6 = 2/3x -6 + 6

8 = 2/3x

We know that two-thirds of x is 8.

We'll divide both sides by 2 to get one third of x!

8/2 = 2/3x / 2

4 = 1/3x

Finally, let's multiply both sides by 3!

4 x 3 = 1/3x x 3

12 = x

<em>If 2/3x + 2 and 4/3x - 6 had the same value, then x would have the value of 12.</em>

Answer:

41

Step-by-step explanation:

an = a1 + (n-1)d

a_n = the nᵗʰ term in the sequence = 10

a_1 = the first term in the sequence = 5

d = the common difference between terms = 4

a10 = 5 + (10-1)4

a10 = 5 + (9)4

a10 = 5 + 36

a10 = 41

Which functions have an axis of symmetry of x = -2? Check all that apply. A. f(x) = x^2 + 4x + 3 B. f(x) = x^2 - 4x - 5 C. f(x)
Snowcat [4.5K]

Answer:

A. f(x) = x^2 + 4x + 3

D. f(x) = -2x^2 - 8x + 1

Step-by-step explanation:

The axis of symmetry is found by h = -b/2a  where ax^2 +bx +c

A. f(x) = x^2 + 4x + 3

  h = -4/2*1 = -2    x=-2

B. f(x) = x^2 - 4x - 5

h = - -4/2*1 = 4/2 =2  x=2  not -2

C. f(x) = x^2 + 6x + 2

h =  -6/2*1 = -3/2 =  x=-3/2  not -2

D. f(x) = -2x^2 - 8x + 1

h = - -8/2*-2 = 8/-4 =-2  x=-2  

E. f(x) = -2x^2 + 8x - 2

h = - 8/2*-2 = -8/-4 =2  x=2  not -2
