What are Linear Pair of Angles?

Linear pair of angles are the pair of angles formed when two lines are intersected at a point forming on a line.

Sum of the measures of angles of linear pair is supplementary.

Linear pair of angles are formed on a line.

So we have the pair of angles given, 12x + 19 and 22x - 9 are a linear pair of angles.

They are supplementary angles.

(12x + 19) + (22x - 9) = 180

12x + 22x + 19 - 9 = 180

34x + 10 = 180

34x = 180 - 10

34x = 170

x = 170 / 34

x = 5

Hence the value of x is 5.

What is the slope of (-3,2) and (6,1)

Answers

Answer: -1/9

Step-by-step explanation:

Find the Slope  (−3, 2) and (6, 1)

Slope is equal to the change in y over the change in x, or rise over run.

[tex]m=\frac{change in y}{change in x}[/tex]

The change in x is equal to the difference in x-coordinates (also called run), and the change in y

is equal to the difference in y-coordinates (also called rise).

    [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute in the values of x and y into the equation to find the slope.

    [tex]m = \frac{1-(2)}{6-(-3)}[/tex]

Simplify the numerator. Tap for more steps...

     [tex]m=\frac{-1}{6-(-3)}[/tex]

Simplify the denominator.

     [tex]m=-\frac{1}{9}[/tex]

Answer:

Approximately -1/9 or -0.111111111.

Step-by-step explanation:

The equation to find slope is m=y2-y1/x2-x1. The m is the slope, and the y's and x's are from the coordinates. The equation will be m=1-2/6-(-3). That becomes -1/9. If you want to find the answer in decimal form, just divide -1 by 9 to get -0.111111111.

I hope this helps!

Answers

Answer:

96π units²

Step-by-step explanation:

Find the diagram attached

Area of a sector is expressed as;

Area of a sector = θ/2π * πr²

Given

θ = 3π/4

r = 16

Substitute into the formula

area of the sector = (3π/4)/2π * π(16)²

area of the sector = 3π/8π * 256π

area of the sector = 3/8 * 256π

area of the sector = 3 * 32π

area of the sector =96π units²

Answer:

0.03A + 0.03B = 800

A + B = 20000

Step-by-step explanation:

Let one part A of the total money invested with 3% interest = $A

Therefore, other part B of the money invested with 5% interest = $B

Interest = Principal amount × Rate of interest × Duration of investment

If the duration is 1 year,

Interest = Principal amount × Rate of interest

Return on part A = A × 0.03

Return on part B = B × 0.05

Total return = $800

So the equations will be,

0.03A + 0.03B = 800 -------(1)

Since, total money invested = $20000

Equation will be,

A + B = 20000 -------(2)
