Answer:

Given equation: x + 2y = 7

Rearrange the given equation to make y the subject:

      \sf x + 2y = 7

\sf \implies 2y=7-x

\sf \implies y = \dfrac12(7-x)

Now input the given x-values into the equation to determine the y-values:

\sf x=-2\implies y = \dfrac12(7-(-2))=4.5

\sf x=-1\implies y = \dfrac12(7-(-1))=4

\sf x=0\implies y = \dfrac12(7-0)=3.5

\sf x=1\implies y = \dfrac12(7-1)=3

\sf x=2\implies y = \dfrac12(7-2)=2.5

\sf x=3\implies y = \dfrac12(7-3)=2

As ordered pairs: (-2, 4.5)  (-1, 4)  (0, 3.5)  (1, 3)  (2, 2.5)  (3, 2)

Plot the endpoints on the graph (-2, 4.5) and (3,2), then connect with a line segment.

What is the value of X???
natta225 [31]

Answer:

x=5

Step-by-step explanation:

The angles of a trangle have to add up to 180 degrees. With that information, we can create an equation:

27+98+(10x+5)=180

125+10x+5=180

130+10x=180

-130         -130

______________

10x=50

/10   /10

x=5
