Answer 1

Answer:

Slope: -3

Equation: [tex]y=-3x-5[/tex]

Step-by-step explanation:

As x increases by 1, your y decreases by 3, making the rise over run [tex]-3/1=-3[/tex]. That becomes the m in your y=mx+b equation, and since you have the y intercept, you can just plug and chug.

If I helped, a brainliest answer would be greatly appreciated!

Answer 2

Answer:

Slope = -3

m = -3 / 1 = -3

Find the slope of the line that passes through points (6,9) and (11,2)

Answers

Answer:

[tex]-1.4[/tex]

Step-by-step explanation:

The slope of a line is the change in the line. It can be found using the formula;

[tex]\frac{rise}{run}[/tex] or [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].

Substitute in the given points, and solve for the slope;

[tex]\frac{y_2-y_1}{x_2-x_1}\\\\= \frac{2-9}{11-6}\\\\= \frac{-7}{5}\\\\= -1.4[/tex]

Answer:

-7/5

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(2-9)/(11-6)

m=-7/5

A random sample of n = 16 scores is obtained from a parent population with σ = 12. If the sample mean is 6 points greater than the population mean, what is the z-score for the sample mean?

Answers

Answer:

0.5

Step-by-step explanation:

Sample mean, x = 6 points greater than population mean ;

Population mean, m = 16

Standard deviation, s = 12

Zscore = (sample mean - population mean) / standard deviation

Zscore = (x - m) / s

x = 16 + 6 = 22

Zscore = (22 - 16) / 12

Zscore = 6 /12

Zscore = 0.5

Paul is going to have the exterior of his home painted. Painting USA charges $75.00 to come out and evaluate the house plus $25.00 per hour of labor. Upscale Home Painting does not charge to evaluate the house. However, they charge $40.00 per hour.

The cost of painting the house will be the same for both companies if the number of hours required to paint Paul’s house is
A- 3 hours
B- 5 hours
C-8 hours

Answers

Answer:

The most cost effective company will be Painting USA that charge $700 to paint Paul house .

As given

Paul is going to have the exterior of his home painted.

Painting USA charges $75.00 to come out and evaluate the house plus $25.00 per hour of labor.

If it takes 25 hours to paint Paul’s house.

Total amount charge by Painting USA = Painting USA charges for come out  and evaluate the house + Cost of per hour of labor × Total hours take to paint Paul house .

Total amount charge by Painting USA = 75 + 25 × 25

                                                               = 75 + 625

                                                               = $ 700

As given

Upscale Home Painting does not charge to evaluate the house. However, they charge $40.00 per hour.

Total amount charge by Upscale Home Painting = Cost of per hour of labor × Total hours take to paint Paul house

                                                                                = 40 × 25

                                                                                = $ 1000

Therefore  the most cost effective company will be Painting USA  that charge $700 to paint Paul house .

Step-by-step explanation:

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the Concept of the Trigonometry.

Here, as the given figure.

We will use the tan ratio to get the value of 'y'.

hence, tan(30°) = 5/y

[tex]since \: \: \tan(30) = \frac{1}{ \sqrt{3} } [/tex]

so we use it here,

y = 5/tan(30)

===> hence,

[tex]y \: \: = 5 \sqrt{3} [/tex]

Answers

Answer:

X=3

Step-by-step explanation:

Rearrange terms

6+3=15

3+6=15

Subtract from both sides of the equation

3+6=15

3+6−6=15−6

Simplify

Subtract the numbers

Subtract the numbers

3=9

x=3

X = 3.

Step-by-step explanation:

1) Subtract 6 from both sides.

[tex]3x = 15 - 6[/tex]

2) Simplify 15 - 6 to 9.

[tex]3x = 9[/tex]

3) Divide both sides by 3.

[tex]x = \frac{9}{3} [/tex]

4) Simplify 9/3 to 3.

[tex]x = 3[/tex]

So, therefor, 5he answer is x=3.
