Answer:

(3, -7) and (1, 2) are solutions to the equation

Step-by-step explanation:

Simply replace the (x, y ) pair of values in the equation and see if the equality holds:

Pair (0, -8) :

9 (0) + 2 (-8) = -16  therefore this pair is NOT a solution of the equation

Pair (3, -7):

9 (3) + 2 (-7) = 27-14 = 13  therefore this pair IS a solution of the equation

Pair (1, 2):

9 (1) + 2 (2) = 9 + 4 = 13  therefore this pair IS a solution of the equation

Pair (4, -5):

9 (4) + 2 (-5) = 36 - 10 - 26  therefore this pair is NOT a solution of the equation

Answer:

D

Step-by-step explanation:

The midpoint is represented as M and the value of x of the line is x = 4

Given data:

The midpoint of a line segment is a point that lies halfway between 2 points. The midpoint is the same distance from each endpoint.

Measure the distance between the two end points, and divide by 2.

Let V ( x₁ , y₁ ) be the first point

Let W ( x₂ , y₂ ) be the second point

The midpoint between A and B is M ( a , b ) where

a = ( x₁ + x₂ )/2

b = ( y₁ + y₂ ) / 2

The points on the lines are represented by ( 4x - 1 ) and ( 3x + 3 )

So, the points are in same distance from V and W

And, 4x - 1 = 3x + 3

x = 4

Hence, the point x = 3

Answer:

Division Property of Equality

Step-by-step explanation:

Hi, the Division Property of Equality states that when we divide both sides of an equation by a non zero number, both sides of the equation stays the same.

In this case, we divide both sides by 9, and the equality remains the same.

9m=180

9m ÷ 9 = 108 ÷ 9.

m = 12

Step-by-step explanation:

In the picture attached, the question is shown.

From the picture:

Ratio m:n, means that m = 1 and n = 2.

Replacing into the formulas:

x-coordinate = m/(m+n) * (x2- x1) + x1 = 1/3 * (-4 - 2) + 2 = 0

y-coordinate = m/(m+n) * (y2- y1) + y1 = 1/3 * (9 - (-3)) + (-3) = 1

Answer: Finding the number of ways to choose 4 letters out of 12

Step-by-step explanation:

The two situations above didn’t even mention letters. One situation mentioned carrot and broccoli out of 10 vegetables. The other situation mentioned Al, Bob and Carl out of a class of 30 students.

The number of letters (4) out of total letters (10) doesn’t matter because it wasn’t one of the two previously mentioned situations.

Answer:

Step-by-step explanation:

if (x,y) is any point on unit circle then

x²+y²=1²

x²+y²=1

(3/4)²+y²=1

9/16+y²=1

y²=1-9/16=(16-9)/16=7/16

y=±√7/16

If the point P = (3/4, y) lies on the unit circle then y = ± 0.66.

The equation for a circle has the generic form x² + y² + 2gx + 2fy + c = 0.

The standard equation of a circle is x² + y² = r².

The polar form of the equation of the circle is (rcosθ)² + (rsinθ)² = p².

We know if (x ,y) is any point on the unit circle then

x² + y² = 1².

x² + y² = 1.

(3/4)² + y² = 1.

9/16 + y² = 1.

y² = 1 - 9/16.

y² = (16 - 9)/7.

y² = 7/16.

y = ± √7/16.

y = ± 0.66.

Answer:

B

Step-by-step explanation:

Equation of circle is (x-x1)^2 + (y-y1)^2 = r^2

So if radius is 5 then radius squared is 25 So it has to be either B or D But

Because the equation is (y-y1)^2 and the y coordinate is 3 then the equation needs to have a -3

So answer is B

Mean Absolute Deviation

The first step is to calculate the mean of the given data;

[tex]Mean = \frac{\sum{x}}{n}[/tex]

where x = 9, 7, 6, 8, 7, 5 and n = 6

[tex]Mean = \frac{9+ 7+ 6+ 8+ 7+ 5}{6}[/tex]

[tex]Mean = \frac{42}{6}[/tex]

[tex]Mean = 7[/tex]

Subtract mean (7) from each data

[tex]9 - 7 = 2\\7 - 7 = 0\\6 - 7 = -1\\8 - 7 = 1\\7 - 7 = 0\\5 - 7 = -2[/tex]

Return the absolute values of each

[tex]|2| = 2\\|0| = 0\\|-1| = 1\\|1| = 1\\|0| = 0\\|-2| =2[/tex]

Calculate mean of the above absolute values

[tex]Mean = \frac{\sum{x}}{n}[/tex]

[tex]Mean = \frac{2+0+1+1+0+2}{6}[/tex]

[tex]Mean = \frac{6}{6}[/tex]

[tex]Mean = 1[/tex]

Hence, the mean absolute deviation of the given data is 1

Step-by-step explanation:

Answer:

a) The independent variable is r, the radius. You can use any allowable number for r. The dependent variable is V, the volume. Once you choose a value for r, the value of V will depend on that value of r.

b) The domain is all real numbers greater than 0. A radius cannot be zero or a negative number.

c) The output of V(8) is the function V(r) evaluated at r = 8, so it is the volume of a sphere of radius 8 units.

Answer:

Independent events

Step-by-step explanation:

They are independent events because by "lands on yellow" and "lands on green", we're assuming that we're doing something like spinning a spinner, because then we're not taking anything and not replacing it. When we're replacing something, then that's an independent event, and by spinning a spinner once, for Event A, and again for Event B, then we're already replacing everything.

Answer: Disjointed

Step-by-step explanation:

The reason why the answer is disjointed is that the events had nothing in common.
