Answer:

x=22

Step-by-step explanation:

To solve, use an important geometry theorem.

The exterior angle of a triangle is equal to the sum of the two opposite interior angles.

Know this theorem, write 6x-7 = 103-x+2x and solve for x.

6x-7=103-x+2x

6x-7=103+x

5x-7=103

5x=110

x=22

Function is a line points (3,2), (5,8), and (8,y) what is y

SashulF [63]

Y = mx + b

$(3;\ 2)\to x_1=3;\ y_1=2\\\\(5;\ 8)\to x_2=5;\ y_2=8\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\to m=\dfrac{8-2}{5-3}=\dfrac{6}{2}=3$

Therefore we have: y = 3x + b.

Put the coordinates of the point (3; 2) to the equation of the line:

$2 = 3\cdot3+b\\2=9+b\ \ \ |-9\\b=-7$

Therefore we have: y = 3x - 7

Substitute the coordinates of the point (8; y) to the equation of the line:

$y = 3\cdot8-7=24-7=17$

Answer: y = 17.

Set 4x equal to x+30 and solve.

prisoha [69]

Answer:

x = 10

Step-by-step explanation:

1) Subtract x from both sides.

4x − x = 30

2) Simplify 4−x to 3x

3x = 30

3) Divide both sides by 3

x = $\frac{30}{3}$

4) Simplify $\frac{30}{3}$ to 10

x = 10
