Write an equation in point-slope form for the line that passes through each point.
(-2, 11), vertical line

Answers

Answer:

You can't make a point=slope form equation.

Step-by-step explanation:

The vertical line would be parallel to y- axis, hence its equation would be x= c . The slope of the vertical line is undefined, therefore there is no point slope form as such.

y-11=0(x+2)

y-11=0

y=11

Step-by-step explanation:

Calculation is done as follows:

Number of movie posters remaining = 120 - 24 = 96

Number of band posters remaining= x  

120:100 = 96:x

x = 80  

100-x = 100 - 80 = 20

So, she should sell about 20 band posters for her to maintain the same ratio of the movie posters to the band posters.

The measure of angles in a triangle are in a ratio of 2:3:4. What are the measures of the angles?

Answers

Answer:

The angle measures are 40°, 60°, and 80°.

Step-by-step explanation:

When we are given this problem, we need to know that

There are three angles in a triangle.These angles add up to equal 180°.

With this ratio, these angles must add up to equal 180°. Therefore, we can set up an equation and add an x-variable to each of the numbers. We then set this equal to 180.

[tex]\text{2x + 3x + 4x = 180}\\\\\text{9x = 180}\\\\\text{x = 20}[/tex]

Now, we need to find the measures of the angles. The angles are the parts of the ratio multiplied by the value of x.

[tex]\text{2(20) = 40}\\\\\text{3(20) = 60}\\\\\text{4(20) = 80}[/tex]

So, our three angles measures should be 40°, 60°, and 80°. We can check this by adding up these three values and seeing if the sum equals 180°.

[tex]\text{40 + 60 + 80 = 180}\\\\\text{100 + 80 = 180}\\\\\text{180 = 180}[/tex]

Because this is true, our angle measures are 40°, 60°, and 80°.

Find the equation of the line that contains the points (-5, 0) and (-3, 4)

Answers

Answer:

y = -1/2x - 5/2

Step-by-step explanation:

With points (-5,0) and (-3,4), we need to find the slope first.

[Find slope of points]

Using slope formula m = (Y2 - Y1) / (X2 - X1)

Using points: m = (4 - 0) / (-3 - 5) = 4/-8 = -1/2

[Use point-slope formula]

(y-y0) = m(x-x0)

Using points: (y - 0) = -1/2(x - -5)

Finally: y = -1/2x -5/2
