A plane is 20,000 ft. In the air and descending at a rate of 25 ft. Per minute. Write an equation​ to represent this situation where y is the height of the plane after x minutes.

Answer:

y= -3x-16

Step-by-step explanation:

slope intercept form is written as y=mx+b.  m is the slope, and b is the y-intercept.  -3=m

we know that (-5,-1) is 5 points away from the origin, and that the slope is -3, so 5 times -3 equals -15.  subtract 15 from -1 (y-coordinate) in order to get the y-intercept (when x=0).

Step-by-step explanation:

You missed a small portion of the question in the end. If I am not mistaken, I am able to find the complete question which you should have added. Anyways, this would help you clear your concept as I would explain the context.

Here is the complete question:

Tanya is printing a report. There are 92 sheets of paper in the printer, and the number of sheets of paper p left after t minutes of printing is given by the function p(t) = -8t + 92.

How many minutes would it take the printer to use all 92 sheets of paper?

Answer:

It would take 11.5 minutes for the printer to use all 92 sheets of paper

Step-by-step explanation:

Given:

To determine:

How many minutes would it take the printer to use all 92 sheets of paper?

Given the function

[tex]p(t) = -8t + 92[/tex]

We know that when all the 92 sheets of paper will be printed, there will be no more sheets left to be printed.

Therefore, we need to substitute p(t) = 0 in the given function to determine the value of time in minutes

[tex]0 = -8t + 92[/tex]

[tex]8t = 92[/tex]

Divide both sides by 8

[tex]\frac{8t}{8}=\frac{92}{8}[/tex]

[tex]t=\frac{23}{2}[/tex]

[tex]t = 11.5[/tex] minutes

Answer:

exactly two factors

Step-by step Explanation:

A prime number is an integer, or whole number, that has only two factors: 1 and itself. Put another way, a prime number can be divided evenly only by 1 and by itself. Prime numbers also must be greater than 1. For example, 3 is a prime number, because 3 cannot be divided evenly by any number except for 1 and 3.

Answer:

x=4

Step-by-step explanation:

h(x)=-x+4

h(x)-0+4

h(x)=4

Answer:

x = 4

Step-by-step explanation:

Given: [tex]h(x) = - x + 4[/tex]

Solve for x, when: [tex]h(x) = 0[/tex]

◇◇•◇◇

[tex] - x + 4 = 0[/tex]

[tex] - x = - 4[/tex]

[tex]\boxed{\green{x = 4}}[/tex]

Answer:

[tex]y^{\frac{2}{5}}[/tex]

Step-by-step explanation:

[tex]2 - \frac{4}{5} = \frac{2*5}{1*5}-\frac{4}{5}\\\\ = \frac{10}{5}-\frac{4}{5}\\\\= \frac{6}{5}[/tex]

[tex]\frac{a^{m}}{a^{n}}=a^{m-n}\\\\[/tex]

[tex]\sqrt[3]{\frac{y^{2}}{y^{\frac{4}{5}}}} =\sqrt[3]{y^({2-\frac{4}{5})}} \\\\=\sqrt[3]{y^{\frac{6}{5}}}\\\\=(y^{\frac{6}{5}})^{\frac{1}{3}} \\\\=y^{\frac{6}{5}*\frac{1}{3}}\\\\= y^{\frac{2}{5}}[/tex]

Answer:

The new width = 2 inches

Step-by-step explanation:

Original dimensions of the rectangular photo:

Length : width = 8 inches : 4 inches

Reduced dimensions of the rectangular photo:

Let

x = the new width

Length : width = 4 inches : x inches

Equate both dimensions to get the value of x

Length : width

8 inches : 4 inches = 4 inches : x inches

8 / 4 = 4 / x

Cross product

8 * x = 4 * 4

8x = 16

x = 16/8

x = 2 inches

The new width = 2 inches

Answer:

I suggest that you use Socratic to solve this.

Step-by-step explanation:

Answer:

[tex]x=\frac{-3}{2}[/tex]

Step-by-step explanation:

[tex]2 + 4 ( x + 1 ) = 0[/tex]

[tex]2 + 4x + 4 = 0[/tex]

[tex]6 + 4x = 0[/tex]

[tex]4x = -6[/tex]

[tex]x = \frac{-3}{2}[/tex]

Answer:

b (5x+4y=32) is the correct answer

Step-by-step explanation:

if it is parallel then the slop has to be the same which means you can eliminate choices a and c. then, you can plug in the points they give you to see if the statement holds true.

5x+4x

5(12)+4(-7)

60-28

32

therefore, option b is correct

Answer: m=2

M stand for measurement

Step-by-step explanation:

(−11,−3);(−6,7)

(x1,y1)=(−11,−3)

(x2,y2)=(−6,7)

Use the slope formula:

m=  y2−y1 /x2−x1

(7−(−3) ) −( 6−(−11) )

= 10 /5

=2

Answer:  m=2
