First question, the answer is C. 2nd question, the answer is A

Explanation: I don’t know how to well explain graphs.. however, on the vertical line, that’s the amount of money the person pays after the amount of months they’ve started their plan. Whether that be beginner, or veteran. If you look, the lines overlap a month which is month 4. This is where they both pay 100$, this is because the 100 lines up at that point. For the 2nd question, the beginner would have paid lower than the veteran because the line is below the first. Hope this helps!

What is the value of x in the equation 2/3(1/2x+12)=1/2(1/3x+14)-3?

Jlenok [28]

Answer:

a. -24

Step-by-step explanation:

Multiply by 6 ...

2/3(1/2x+12)=1/2(1/3x+14)-3

4(1/2x +12) = 3(1/3x +14) -18 . . . . . . multiply by 6

2x +48 = x +42 -18 . . . . . . . . . . . . . .eliminate parentheses

x = 24 -48 = -24 . . . . . . . . . . . . . . . . simplify and subtract (x+48)

For each ordered pair determine whether it is a solution to the system of equations 2x-7y=8 -3x+2y=5

rodikova [14]

Answer:

The solution of this system of linear equations is $(x,y) = (-3,-2)$ .

Step-by-step explanation:

Let be the following system of linear equations:

$2\cdot x - 7\cdot y = 8$ (1)

$-3\cdot x + 2\cdot y = 5$ (2)

From (1) we clear $y$ :

$2\cdot x -8 = 7\cdot y$

$y = \frac{2\cdot x - 8}{7}$

And we apply this variable in (2):

$-3\cdot x+2\cdot \left(\frac{2\cdot x -8}{7} \right)= 5$

$-3\cdot x +\frac{4}{7} \cdot x -\frac{16}{7} = 5$

$-\frac{17}{7}\cdot x = \frac{51}{7}$

$x = -\frac{51}{17}$

$x = -3$

And the value of $y$ is:

$y = \frac{2\cdot (-3)-8}{7}$

$y = -\frac{14}{7}$

$y = -2$

The solution of this system of linear equations is $(x,y) = (-3,-2)$ .
