Find the measure of CB.

Answer:

29 units

Step-by-step explanation:

Answer:

29 is the distance between the points (-30, -10) and (-30, 19) in the xy-plane.

Step-by-step explanation:

I've answered the question written, not the one in the picture.

You can either use the distance formula, [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex], or do Y2-Y1 (since the x-value is the same).

Answer:

Step-by-step explanation:

a)

The slope as per two ordered pairs (-2, -10), (0, -2)

The y-intercept is -2

The equation for this function:

b)

The slope is

The line passes through (1, 5)

The line is:

c)

The slope as per points on the graph (3, 0), (4, 2)

The line in point slope form using point (3, 0):

The line in slope-intercept form:

a) substitute m = 4 and c = - 2 into the slope intercept equation, thus, the equation of the line is y = 4x - 2

The answer is y = 4x - 2

b) Let's begin by listing out the given information:

The line has a slope of 3

The equation of the line becomes:

[tex]y = mx + b \\ m = 3 \\ y = 3x + b[/tex]

The line passes through point (1, 5).

We will obtain the equation using the point-slope formula, we have:

[tex]y - y1 = m(x - x1) \\ (x1 \: y1) = (1 \: 5) \\ y - 5 = 3(x - 1) \\ y - 5 = 3x - 3 \\ y = 3x - 3 + 5 \\ y = 3x + 2[/tex]

Therefore, the equation of the straight line is y = 3x + 2

c) we use that point and the slope to replace in the expression:

[tex]y - y1 = m(x - x1)[/tex]

That is:

[tex]y - 0 = 2(x - 3) \: \: y = 2x - 6[/tex]

y = 2x - 6 is the answer

Answer:

The equation is:

y = -15*x + 1200

and:

a = 120

b = 70

c = -1500

Step-by-step explanation:

This seems to be a linear relationship.

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

Here we know that our line passes through the points (60, 300) and (20, 900)

Then the slope of this line is:

a = (900 - 300)/(20 - 60) = 600/(-40) = -15

Then this line is something like:

y = -15*x + b

To find the value of b, we know that this line passes through the point (60, 300) then when x = 60, we have y = 300.

Replacing these values in the above equation we get:

300 = -15*60 + b

300 + 15*60 = b = 1200

Then:

y = -15*x + 1200.

Now that we have this equation, we can complete the table.

a is the value for y, when x = 72

Then we can replace x by 72 in the above equation:

a = -15*72 + 1200 = 120

a = 120

b is the value of x when y = 150, then we need to replace y by 150

150 = -15*b + 1200

150 - 1200 = -15*b

(150 - 1200)/-15 = b = 70

then:

b = 70

c is the value of y when x = 180, then we need to replace x by 180.

c = -15*180 + 1200

c = -1500

Step-by-step explanation:

A proportional relationship is when the graph starts from the origin, (0, 0).

Answer:

Step-by-step explanation:

Factoring will reveal the solution. So we divide the equation by the greatest common factor of the terms and use that factor as the coefficient. In this case the greatest common factor is just x.

2x^2+5x

x(2x+5) so the equation will equal zero when either of those expressions is zero because zero times anything is zero. x=0 and x=-5/2

Answer:

[tex]x = 0, -\frac{5}{2}[/tex]

Step-by-step explanation:

First move all terms to one side of the equation to set them equal to 0

That is already done in your problem

The try to factor, if possible.  In your case, factor out x

x(2x + 5) = 0   Now, use the property that says if AB = 0, then A = 0 or B = 0 or both A and B equal 0

So, x = 0    or   2x + 5 = 0

                             2x = -5

                               x = [tex]-\frac{5}{2}[/tex]

Always check your results in the original equation to see if they work

[tex]2(0^{2} + 5(0) = 0 + 0 = 0\\[/tex]

and [tex]2(-\frac{5}{2} )^{2} + 5(-\frac{5}{2} )\\ = 2(\frac{25}{4} ) - \frac{25}{2} \\ = \frac{25}{2} - \frac{25}{2} = 0[/tex]

Both results make the equation true, so [tex]x = 0, -\frac{5}{2}[/tex]

Answer:

16640x²

Step-by-step explanation:

using angle sum property

we get

110+35+(x+12)=180

(x+12)=180-145

(x+12)= 35

x= 35-12

x= 23

Answer:

Angles in a triangle are sum up to 180 degrees.

35 + 110 + (x+12)=180

145+x+12=180

157+x=180

x=180-157

Given:

[tex]\log_{a}(3) = 0.477,\log_{a}(5) = 0.699[/tex]

To find:

The value of [tex]\log_{a}(0.6)[/tex].

Solution:

We need to find the value of:

[tex]\log_{a}(0.6)[/tex]

It can be written as

[tex]\log_{a}(0.6)=\log_a\left(\dfrac{6}{10}\right)[/tex]

[tex]\log_{a}(0.6)=\log_a\left(\dfrac{3}{5}\right)[/tex]

By using the property of logarithm, we get

[tex]\log_{a}(0.6)=\log_a(3)-\log_a(5)[/tex]        [tex][\because \log \dfrac{a}{b}=\log a-\log b][/tex]

[tex]\log_{a}(0.6)=\log_a(3)-\log_a(5)[/tex]

On substituting the given values, we get

[tex]\log_{a}(0.6)=0.477-0.699[/tex]

[tex]\log_{a}(0.6)=-0.222[/tex]

Therefore, the values of [tex]\log_a(0.6)[/tex] is -0.222.

Answer:

y=x+10

Step-by-step explanation:

it's a guess. it goes up 1 over 1 so the "m" in y=mx+b has to be 1. so x stands alone. the line looks like it begins at 10 so the b will equal 10

Answer:

y = 5x + 10

Step-by-step explanation:

Line is passing through the points (2, 20) & (4, 30)

Slope of line (m) = (30 - 20)/ (4 - 2) = 10/2 = 5

y - 20 = 5(x - 2)

y = 5x - 10 + 20

y = 5x + 10

Answer:

(-2, -3)

Step-by-step explanation:

We are given y = 3x + 3 and y = x - 1.

We can substitute y = x + 1 into the y value for y = 3x + 3, so

x - 1 = 3x + 3  Now, we just subtract x from both sides.

-1 = 2x + 3  We subtract 3 from both sides.

-4 = 2x

2x = -4  We divide both sides by 2

x = -2  Now we have our x value - (-2, y)

Let's substitute the x value into both of the equations given.

1st equation:

y = 3(-2) + 3

y = -6 + 3

y = -3

2nd equation:

y = (-2) - 1

y = -3

We now know that both equations give us the same y value when x = -2 is substituted, therefore our solution is:

(-2, -3)

The solution for the pair of equations is (-2,-3).

A system of equations is a set or collection of equations that you deal with all together at once. For a system to have a unique solution, the number of equations must equal the number of unknowns.

For the given situation,

The pair of equations are

y = 3x + 3 ------- (1)

y = x − 1 -------- (2)

Substitute the equation 2 in equation 1, we get

⇒ [tex]x-1=3x+3[/tex]

⇒ [tex]3x-x=-1-3[/tex]

⇒ [tex]2x=-4[/tex]

⇒ [tex]x=-2[/tex]

Now substitute x in equation 2,

⇒ [tex]y=-2-1[/tex]

⇒ [tex]y=-3[/tex]

Hence we can conclude that the solution for the pair of equations is (-2,-3).

Answer:

the answer is c 1.2

Step-by-step explanation:

to calculate the iqr you have to do the following:

q3 - q1 = answer

4.5 - 3.3 = 1.2

The IQR(interquartile range) for the distribution of the song length is 1.2.

Interquartile range gives information on the spread of the middle half of your distribution.

Mathematically, the interquartile range can be represented as follows:

IQR = Q₃ - Q₁

where

Q₃ = 4.5

Q₁ = 3.3

Therefore,

IQR = 4.5  - 3.3

IQR = 1.2

Therefore, the interquartile range is 1.2.
