No, because there are TWO values of y for a certain value of x

say x=5, then y=2 and y=-2

That does not satisfy the concept of the function.

Answer:

No

Step-by-step explanation:

To check the given graph of a relation is function or not.

Using graph check for function by vertical line test.

Draw numbers of vertical line. If any of one vertical line intersect the graph at two different points then graph is not a function.

Now check the graph using vertical line.

Draw 3 vertical line. All three vertical line intersect graph at two points.

Please have a look in attachment.

So, The graph of relation is not a function because vertical line test not pass.

-1/2(3x-4)+3x=5/6<br> Please help
Ksenya-84 [330]

Answer:

  x = -7/9

Step-by-step explanation:

The usual recommendation is to clear fractions first. Here, you can do that by multiplying both sides of the equation by 6.

  6(-1/2(3x -4) +3x) = 6(5/6)

  -9x +12 +18x = 5 . . . . . . . . . simplify

  9x = -7 . . . . . . . . . . . . . . . . . subtract 12

  x = -7/9 . . . . . .divide by 9

__

Another way to do this is to eliminate parentheses first.

  -3/2x +2 +3x = 5/6

  3/2x = -7/6 . . . . . . . . . collect terms, subtract 2

  x = (-7/6)(2/3) = -7/9 . . . . multiply by 2/3

14x+7y=217 <br> 14x+3y=189
kondor19780726 [428]

Answer:

y = 7

x = 12

Step-by-step explanation:

14x+7y=217, then 14x = 217 - 7y

14x+3y=189, then 14x = 189 - 3y

217 - 7y = 189 - 3y

add 7y to each side of the equation:

4y + 189 = 217

subtract 1890 from each side:

4y = 28

divide both sides by 4:

y = 7

14x + 3(7) = 189

subtract 21 from each side:

14x = 168

divide both sides by 14:

x = 12

Solve this equation <br>4-2x-12-2x+1
alina1380 [7]
This is not an equation because it lacks an equal sign....so the only thing we can do here is combine like terms.
4 - 2x - 12 - 2x + 1 =
-4x - 7
