Answer:

The y-intercept of points A and B is -2.

Step-by-step explanation:

Point A is the y-intercept. You can tell by looking at the x and seeing that it is 0. This means the point is the y-intercept.

Answer:

-2

Step-by-step explanation:

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis). To solve this question, first, find the slope, then, plug one of the given points into the equation to isolate b.

1) Find the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (0,-2) and (3,0)

[tex]m=\frac{0-(-2)}{3-0}\\m=\frac{0+2}{3}\\m=\frac{2}{3}[/tex]

Therefore, the slope of of the line is [tex]\frac{2}{3}[/tex]. Plug this into  [tex]y=mx+b[/tex] as m:

[tex]y=\frac{2}{3} x+b[/tex]

2) Find the y-intercept (b)

[tex]y=\frac{2}{3} x+b[/tex]

Plug in one of the given points: (0,-2) or (3,0)

[tex]0=\frac{2}{3} (3)+b\\0=2+b\\b=-2[/tex]

Therefore, the y-intercept of the line AB is -2.

Answer:

a) $30

b) 30

Step-by-step explanation:

a) Her starting pay is $60. After an hour it goes up to $90. 90-60=30.

b) Every hour, the pay goes up 30.  Slope is calculated as the change in y divided by the change in x. That means 30/1, or just 30 is the slope.

Answer:

60 degrees

Step-by-step explanation:

ACD and ACB are complementary angles. Find ACB=30 degrees. Subtract 30 from 90 degrees. ACD=60 degrees.

Answer:

ACD=60

BCA=30

BCD=90

90-30=60

Answer:

The listed size is 32 inches

Step-by-step explanation:

Given

See attachment for television

Required

The listed size

The listed size is calculated by the diagonal of the television.

This is calculated as using Pythagoras theorem as follows:

[tex]Diagonal^2 = Length1^2 + Length2^2[/tex]

Where:

[tex]Length1 =28in[/tex]

[tex]Length2 =15.7in[/tex]

So, we have:

[tex]Diagonal^2 = 28^2 + 15.7^2[/tex]

[tex]Diagonal^2 = 784 + 246.49[/tex]

[tex]Diagonal^2 = 1030.49[/tex]

Take positive square roots of both sides

[tex]Diagonal = \sqrt{1030.49[/tex]

[tex]Diagonal = 32[/tex] --- approximated

Hence, the listed size is 32 inches

Answer:

x = 10.3

y = 5.8

Step-by-step explanation:

To find both x and y, you can use the formula [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]

a and b would be the sides that touch the right angle

so to find x, you would do [tex]9^{2}[/tex] + [tex]5^{2}[/tex] = [tex]x^{2}[/tex]

this would be: 81 + 25 = [tex]x^{2}[/tex]

then add it and you get: 106 = [tex]x^{2}[/tex]

now do the square root of 106 to get: 10.3 = x

Now plug in your other values to get y: [tex]5^{2}[/tex] + [tex]3^{2}[/tex] = [tex]y^{2}[/tex]

do the same thing here: 25 + 9 = [tex]y^{2}[/tex]

add your numbers: 34 = [tex]y^{2}[/tex]

square root 34: 5.8 = y

Please don't give me credit, but I want to say that;

1. You need a picture attached to this

2. Make sure you add if 5 feet is the length or width, in addition to the 3 feet

3. The width can't be a negative value, so eliminate the negative answers

4. For the second answer, why is there a coma preceding another value? The width can can only be one value

You can add all these elements

Answer:

A. The division property of equality

Step-by-step explanation:

To get x you need to find a way to get it by itself, which can be done by dividing -3 from both sides of the equation (which is the division property of equality).

For example,

-3x=21

/-3  /-3

x=21/-3

x=-7

Answer:

0.4, 0.8, 1.2 ,1.6 ,2.0

Step-by-step explanation:

First we have to find what the question is really asking and get rid of unwanted or not needed information. It is asking to write a numeric sequence for the first 5 minutes of the 30 minutes.

Second we need to find the pattern. So lets divide $12 by 30. That will equal 0.4 a minute.

Last we add 0.4 for each minute. 0.4 is the first, then 0.8 is 2 minutes, then 1.2 and etc.

The numeric sequence is 0.4, 0.8, 1.2 ,1.6 ,2.0

Here we have to divide $12 by 30. That will equal 0.4 a minute.

Now if we add 0.4 for each minutes

So the series be like

0.4 for the first, 0.8 is 2 minute and so on.

Answer:

Angle A = 30.8

Angle B = 33.2

Step-by-step explanation:

180 - 116 = 64  

This means that the other two angles need to add up to 64.

I just plugged in numbers until it worked.

I got that x = 14.6

2x + 4

2(14.6) + 4

29.2 + 4

33.2

3x - 13

3(14.6) - 13

43.8 - 13

30.8

Those are your angles. To make sure they are correct you just need to add up all the angles and make sure that they equal to 180.

116 + 33.2 + 30.8 =

180

Answer:

the total price of the CD including tax is $11.984

Step-by-step explanation:

The computation of the total price of the CD including tax is shown below:

The Selling price of the CD is $14

CD is 20% off

And, the sales tax rate is 7%

So, the total price of the CD is

= ($14 - $14 × 20%) × (1.07)

= $11.2 × 1.07

= $11.984

Hence, the total price of the CD including tax is $11.984

Answer:

Step-by-step explanation:

there cannot be two of the same x value's. It would make it a circle on the graph, or something close to that, which isn't a function.

Answer:

B

Step-by-step explanation:

So wiggly, remember that slope is change in y/change in x, or in simpler terms, y/x. Thinking of this, y/x must simplyfy to -3. Or, you can think of it as -3/1.

So know that we have rewrote this as a slope of -3/1, lets use it. Where do we start? Well, we must start at point A, which is at 2 x and 7 y.

Now, going to the  RIGHT(+1x) and going DOWN(-3y) we will go from 2x and 7y to 3x and 4y.

Are we on a point yet? Nope, lets do this again.

Now going to RIGHT again(+1x) and going DOWN again(-3y) we will go from 13x and 4y to 4x and 1y.

Are we on a point yet? Still no, lets try this one more time.

Now going to RIGHT again(+1x) and going DOWN again(-3y) we will go from 4x and 1y to 5x and -2y.

Are we on a point? YUP. We cna see that point B is at 5x and -2y.

Hope you get it right ;)

Answer and Step-by-step explanation:

To find the length of AB, we have to use Distance Formula.

Distance Formula takes two points on a graph, and puts it into the following formula to calculate the distance between those two points.

The formula:

D = [tex]\sqrt{(x_{2} - x_1)^2 + (y_2 - y_1)^2 }[/tex]

Where:

D = The Distance between two points

[tex]x_2[/tex] = The x value of the second point

[tex]x_{1}[/tex] = The x value of the first point

[tex]y_2[/tex] = The x value of the second point

[tex]y_{1}[/tex] = The x value of the first point

Point A will be the first point and point B will be the second point. All we have to do now is plug those points into the formula and solve.

[tex]\sqrt{(10 - 5)^2 + (0 - 10)^2 }\\\\\\\\\sqrt{(5)^2 + (- 10)^2 }\\\\\\\\\sqrt{25 + 100 }\\\\\\\\\sqrt{125}\\\\\\\\\sqrt{125} = 5\sqrt{5}[/tex]

The length of side AB is [tex]5\sqrt{5}[/tex] units, or 11.18 units.

Answer: 550

Explanation:

Well first, you need to solve 40 percent of 900 (which is 360) then subtract it from the main amount (900)

So 900-360

Answer:

360

Step-by-step explanation:

So we have 40% and 900 people. Before we ask ourselves what is 40 percent of 900, lets ask ourselves what is 10 percent. So 10 percent of 900 would be 90 because you have to move the decimal point 1 unit to the left.        

Now, 40 percent is 4 times the value of 10 percent so 40 percent of 900 has to be 360, because 90 times 4 is 360.

And you can check it by multiplying 900 x .40 which would be 360

Hope this helped, good luck :)
