Solve for x

3x−8≤23 AND −4x+26≥6

Answer:

Step-by-step explanation:

Step one:

Let A be the altitude of the plane

Hence we can define a function that represents this scenario.

the rate at which the plane's altitude decreases is

=33000-17000/8

= 16000/8

=2000

The rate of decrease is 2000 ft per minute.

Thus for anytime "t" the expression for the altitude is

S=33000-2000t-------where t is the time in minute.

say we want to find altitude after 12 minutes

then t=12

substitute  in the expression we have

S=33000-2000(12)

S=33000-24000

S=9000ft

Answer:

Part 1)  Descending Rate = -2,000 ft/min

Part 2)  Starting altitude value is 33,000 ft

Part 3)  The linear equation for the plane's altitude (y) as a function of time (x) is:  

Part 4)  The information not used for the equation is that the plane was travelling for 4 hours to cover 1800 miles before starting the descent

Step-by-step explanation:

Part 1)

The rate at which the airplane descends is given by the difference between final and initial altitude (17,000 ft-33,000 ft) divided the elapsed time (8 minutes):

Part 2)

When graphing the descent (that is the plane's altitude as a function of time), the starting value for the altitude should be 33,000 ft

Part 3)

We can build the equation of the plane's altitude as a function of time in slope y-intercept form y = m x + b

by noticing that the slope "m" stands for the rate of descent that we found in part 1), and then using the information that at time zero (when the plane starts its descent), its altitude is 33000 ft:

with this information about the intercept "b", we can write the final expression for the plane's altitude as a function of time during its descent as:

Part 4)

The information that was not used to write the descent equation was the initial details about how long the plane traveled (4 hours) and for 1800 miles.

Step-by-step explanation:

Answer:

Not a function

Step-by-step explanation:

For every input there is one and only one output. So on this graph, it shows that there are two dots on a single vertical line, which means that there are two outputs. Because the definition of a function is "for every input there is one and only one output" we know that it is not a function.

Answer:

A) - 54.48

Step-by-step explanation:

Just plug it into the calculator like this;  (-68.1) x 0.8, which equals -54.48.

the answer is negative because you multiplied a positive # and a negative #.

Answer:

This description translated into an inequality is

x + 15 > 124

x > 109

X is greater than 109

This means that the smallest integer that satisfies this inequality is 110 because X cannot be 109 or less; it is greater than 109.

We did not say 109.1 or 109.2 or 109.99 because it is asking for an integer, which cannot be a decimal.

7 . 3 - 3 . 3

= 21 - 9

= 12

Just substitute you y = 3 into the equation

Answer:

The correct answer is 12.

Step-by-step explanation:

To solve this problem, we must plug in 3 for each occurrence of y in the expression because we are given that y = 3.  In this case, we will get the following:

7y - 3y

7(3) - 3(3)

To evaluate, we must simplify this expression.  Due to the order of operations, we should compute the multiplication first.  7*3 = 21 and 3*3=9, so we can plug in these values into our expression.

21 - 9

Now, we can perform the subtraction.

21-9=12

Therefore, the correct answer is 12.

Answer:

1) slope m=-4

2) slope m=-5/4

3) slope m=1

4) slope m=-2

5) slope m=3/5

6) slope m=5/8

Step-by-step explanation:

Slope equation: m=y2-y1/x2-x1

With our slope equation can get just use the graph and choose two points that the line crosses over.

Question 1 example) I chose points (0,-3) as my x1, y1, and point (1,-1) as my x2, y2. I plugged the numbers into the equation and got -1-3/1-0=-4. Which is why our slope is -4

The rest of the questions follow the same concept of Finding two points, decide which one is your x1, y1 and which one is you x2, y2 (does not matter which one you associate with each point), plug the numbers in, and calculate the slope.

(I may be wrong because the graph is a little blurry)

The length of BC in the right triangle is 82 units

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

From the given triangle the line segment AB is 18 units

AC is 80 units

We have to find BC

By using pythagoras theorem we find the length of segment BC

BC²=AB²+AC²

BC²=18²+80²

BC²=324+6400

=6724

BC=√6724

BC=82

Hence, the length of BC in the right triangle is 82 units

The reasonable price of the car after 4 years will be $8618.

Regression analysis is a group of statistical procedures used in statistical modelling to determine the associations between a dependent variable and one or more independent variables.

Given that a dealership tracks the correlation between the age of its used cars and asking price for a car. The regression line is y = 12,338 – 930x, where x is the age of the car, in years.

The price of the car after 4 years will be calculated as follows:-

y = 12338 - 930x

y = 12338 - ( 930 x 4 )

y = 12338 - 3720

y = $8618

Therefore, the reasonable price of the car after 4 years will be $8618.
