Answer:

y = -5x - 11

Step-by-step explanation:

First we are going to find the slope of the function using the formula attached below as an image:

(-5, 14)

(1, -16)

x_1 = -5

x_2 = 1

y_1 = 14

y_2 = -16

Now plug in the values and start simplifying:

(-16 - 14)/(1 - (-5))

(-30)/(6)

-5

The slope is -5.

Now we're going to use the point-slope formula to find the final function:

(point-slope formula has been attached as an image as well)

I'm going to use the point (-5, 14) for this formula:

y - 14 = -5(x + 5)

y - 14 = -5x - 25

y = -5x - 11

That's your answer! Hope this helps (●'◡'●)

Answer:

x = 27 , ∠ EAF = 27°

Step-by-step explanation:

∠ GAF = 90° , then

∠ GAC + ∠ CAF = ∠ GAF , that is

x + 63 = 90 ( subtract 63 from both sides )

x = 27

∠ DAE = 90°

since CD is a straight angle of 180° , then

∠ CAE = 90° , so

∠ CAF + ∠ EAF = ∠ CAE , that is

63° + ∠ EAF = 90° ( subtract 63° from both sides )

∠ EAF = 27°

The mean bonus paid by large companies to their executives is $5 million and the modal class is 3.5-6.5.

To find the mean, we need to find the midpoint of each class and multiply it by the frequency, then add up all of these values and divide by the total frequency:

Class boundaries Midpoint Frequency Midpoint x Frequency

0.5-3.5 2                          11                                         22

3.5-6.5 5                          12                                        60

6.5-9.5 8                           4                                        32

9.5-12.5 11                           2                                       22

12.5-15.5 14                           1                                        14

Total 150  

Mean = (Midpoint x Frequency) / Total Frequency

Mean = 150 / 30

Mean = 5

Therefore, the mean bonus paid by large companies to their executives is $5 million.

To find the modal class, we need to look for the class with the highest frequency. In this case, the class with the highest frequency is 3.5-6.5, with a frequency of 12. Therefore, the modal class is 3.5-6.5.

The algebraic expression of the situation above is 4x - 100 = 400

Let

the amount of ice cream they serve in July = x + 100

the amount of ice cream they serve in June = x

They served twice as many customers in august as they did in June.

Therefore,

the amount of ice cream they serve in August = 2(x)

the amount of ice cream they serve in August = 2x

Therefore,

2x + x  + x + 100 = 400

4x - 100 = 400

4x = 500

x = 500 / 4  

x = 125

Answer:

Option B

Step-by-step explanation:

The median is the middle in a list of sorted nunbers, so it would be 9 in this case.

Explanation:

We are given the sides are congruent due to the tickmarks. Specifically

TU = WV (single tickmarks)

TV = WX (double tickmarks)

So we just need the "A" of "SAS". The A is between the two S letters, so the angle is between the two sides. For triangle TUV, the angle T is between the two sides with the tickmarks. Similarly, angle W is between the tickmarked sides of triangle WVX.

If we know that angle T = angle W, then we have enough information to use SAS.

Antonio needs to score at least 111 points in his next game to reach his goal of an average of at least 100 points per game.

What are basic arithmetic operations?

Basic arithmetic operations are fundamental mathematical calculations that involve manipulating numerical values using a set of basic operations.

To find out how many points Antonio needs to score in his next game to reach an average of at least 100 points per game, we can use the following formula:

Total points needed = (number of games + 1) × average score goal - total points scored so far

In this case, Antonio has played 5 games, so the number of games he will have played after his next game is 6. His goal is an average of 100 points per game, so his average score goal is 100. The total points he has scored so far is:

105 + 95 + 97 + 82 + 110 = 489

Substituting these values into the formula, we get:

Total points needed = (6) × (100) - 489

Total points needed = 600 - 489

Total points needed = 111

Hence, Antonio needs to score at least 111 points in his next game to reach his goal of an average of at least 100 points per game.

None of the given system of linear inequalities

Step-by-step explanation:

Given

\((x,y) =(3,-2)\)

Required

The line inequalities with the above solution

The first set of linear inequalities, we have:

\(y < -3\)

\(y \ge \frac{2}{3}x - 4\)

\(y < -3\) implies that the values of y is -4,-5.....

While \((x,y) =(3,-2)\) implies that y = -2

Hence, the first set is wrong

The second set of linear inequalities, we have:

\(y > - 2\)

\(y \ge \frac{2}{3}x - 4\)

\(y > - 2\) implies that the values of y is -1,0.....

While \((x,y) =(3,-2)\) implies that y = -2

Hence, the second set is wrong

The system of linear inequalities having the point (3, -2) in its solution set is y > -3; y ≥ 2/3x - 4.

A system of linear inequalities is known to be a composition of  linear inequalities that can be found in the same variables.

The graph that is showing  y > -3; y ≥ 2/3x - 4

-2 > -3  is true

y ≥ 2/3x - 4

Step-by-step explanation:

100% = $27.50

1% = 100%/100 = $27.50/100 = $0.275

the extra amount paid (for the tip) was

$32.45 - $27.50 = $4.95

to know how many percent that is, we need to see how often 1% fits into that amount.

so,

4.95 / 0.275 = 18

therefore the tip was 18%.

FYI - in real life the tip percentage (and corresponding amount) is calculated based on the net bill (the amount before sales tax).

Answer:

21°

Step-by-step explanation:

In an sosceles trapezoid, the lower base and upper base angles are congurent

⇒ ∠HGF = ∠EFG

⇒ 9y + 3 = 8y + 5

⇒ 9y - 8y = 5 - 3

⇒ y = 2

⇒ ∠HGF = 9(2) + 3

= 18 + 3

= 21

The measure of angle HGF in the given isosceles trapezoid EFGH is calculated to be 21 degrees.

This problem deals with the properties of an isosceles trapezoid, which is a type of quadrilateral. In an isosceles trapezoid, opposite angles are equal. In this case, angle EFG and angle HGF would be equal to each other given the shape is an isosceles trapezoid. So, their measures should be equal.

Here, the measure of angle HGF is given as (9y + 3)°, and the measure of angle EFG is (8y + 5)°. Setting these equal to each other to find the value of y, we get 9y + 3 = 8y + 5. By simplifying, we get the value of y is 2. Substituting the found value of y in angle HGF we get, 9*2+3 = 21 degrees.

A function, in mathematics, refers to an expression that describes a relationship between two variables - the independent variable and the dependent variable. A function from a set X (independent variable) to a set Y (dependent variable) assigns to each element of X exactly one element of Y. The set of all possible input values for the independent variable is called the domain of the range. The values resulting from the substitution of the domain represent the range of a function which are set of all values of the dependent variable.
