Answer:

x = 5

Step-by-step explanation:

the supplementary angle of (19x-18) = 180 - (19x-18) = 198-19x

all interior angles of a triangle = 180 degrees

180 = (7x+1) + (10x-9) + (198-19x)

180 = 7x+10X-19x+1-9+198

180 = -2x+190

-2x = -10

x = 5

Use the table to answer the question.

Vesna [10]

Given:

The table of values of a linear relationship.

x y

-1 -1

0 1

1 3

2 5

To find:

The equation for the given table of values.

Solution:

If a linear function passes through the two points, then the equation of the linear relationship is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

Consider any two point from the given table. Let the two points are (-1,-1) and (0,1). So, the equation of the linear relationship is

$y-(-1)=\dfrac{1-(-1)}{0-(-1)}(x-(-1))$

$y+1=\dfrac{1+1}{0+1}(x+1)$

$y+1=\dfrac{2}{1}(x+1)$

$y+1=2(x+1)$

Using distributive property, we get

$y+1=2(x)+2(1)$

$y+1=2x+2$

Subtracting 1 from both sides, we get

$y+1-1=2x+2-1$

$y=2x+1$

Therefore, the required equation is $y=2x+1$ . Hence, the correct option is D.
