I need help ASAP I will put answer on Brainliest​

Answers

Answer 1

Answer:

A choice.

Step-by-step explanation:

Irrational number is a number that cannot be written in a fraction form. All square roots are classified as an Irrational number unless can be evaluated to Rational number.

From A choice, you cannot evaluate the square root of 7 into any rational number. Therefore, it is an Irrational number.

B choice, even though there is a square root, but you can still evaluate from square root of 4 to 2.

For C and D, both are integers. Integers are classified to be Rational Number. Therefore, C and D both are rational.

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.

The measure of central angle XYZ is StartFraction 3 pi Over 4 EndFraction radians. What is the area of the shaded sector? 32Pi units squared 85 96Pi units squared 256Pi units squared

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:

96π units²

Write an equation in slope-intercept form of the line that passes through (2,-2) and slope of -4

Answers

Answer:

         y = - 4x + 6          

Step-by-step explanation:

Starting with the point-slope form of the equation {y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope}:

m = -4

(2, -2)    ⇒   x₀ = 2,  y₀ = -2

So, the point-slope form of the equation:

y + 2 = -4(x - 2)

Therefore:

y + 2 =  - 4x + 8         {subtract 2 from both sides}

y = - 4x + 6             ←  the slope-intercept form of the equation

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.
