Answer:

x= -2 , y=5

Step-by-step explanation:

(x+3x)/2 = -4

4x/2 = -4

4x= -8

x = -2

(2y+4y)/2=15

6y/2=15

6y=30

y=5

Answer:

\sf x=-2 \:   \: \: and \:  \:  \: y=5

Step-by-step explanation:

\frac{\sf (x+3x)}{2}  = - 4

\frac{\sf 4x}{2}  =  - 4

\sf 4x = -8

\sf\huge x=-2

_____________________________________

\frac{\sf (2y+4y)}{2}  = 15

\frac{\sf 6y}{2}  = 15

\sf 6y=30

\sf\huge y=5

What is the slope of the line that passes through the points (2,1) and (17,-17)​
Gnoma [55]

hi

You have two points     A ( X;Y)  and B ( X ; Y)

slope is   :    ( Yb -Ya)   / (Xb -Xa )

A(2 ; 1)  and  B (17 ; - 17)  

so   :  (-17 - 1 )  / (17 -2) =  -18/ 15 =  - 6*3 / 5*3 =  -6/5

What is the value of y in the solution set of the system of linear equations shown
zaharov [31]
The answer will be 10 because you plug in y=-×+12 in the equation 4x-2y=36. After you solve and do distributive property your new equation should be 4x+2x-24=36, then you add the like terms of 4x and 2x which will equal to 6x and your new equation should be 6x-24=36. Add 24 from both sides and your equation should be 6x=60, then you divide 60 by 6 and your final answer will be x=10 or 10

Does this graph represent a function? Why or why not?
kobusy [5.1K]

Answer:

Option (C).

Step-by-step explanation:

In the graph attached,

An absolute function has been given.

To check a graph whether it's a relation or a function, vertical line test is a trusted tool.

In vertical line test a vertical line (parallel to y-axis) is drawn passing through the graph.

If the vertical line cuts the graph at only one point then the graph is said to be a function.

The given graph passes the vertical test.

Therefore, it's a function.

Option C. will be the answer.
