if x is changed by 2 , the y changes by  +3, Option B is the correct answer.

The equation of a Linear Function is given by

y = mx +c

here m is the slope , c is the intercept on the y axis

The data is given in the table

To determine the relation , a function needs to be established between the variables.

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

m = (-7 +10) /(-2+4)

m = 3 / 2

y = (3/2)x + c

at x = 0 , y= -4

-4 = 0 + c

c = -4

The function is

y = (3/2) x - 4

if x is changed by 2 , the y changes by  +3

Therefore Option B is the correct answer.

Answer:

C

Step-by-step explanation:

Total Work hours = 3 1/2 hours

One routine physical routine requires: 1/3 hours.

Number of routines can be completed = Total work hours / Time required for one physical routine

= [tex]3\frac{1}{2} / \frac{1}{3}\\=\frac{7}{2} /\frac{1}{3} \\=\frac{7}{2} *3\\[/tex]

= 10.5 routines.

In this case, we are unable to complete half a routine (0.5), so we will choose the highest possible whole number, in this case, its 10 routines.

Answer:

B. 2.85

Step-by-step explanation:

to find the average of multiple numbers, we add them together and divide by the number of values we combined

for example: the average of 1, 2, and 3:

1 + 2 + 3 = 6

6 / 3 (because there were 3 numbers) = 2

so, this average would be 2.

Let's add the weights (I have changed these into a denominator of 20, so that they can be easily added. Let me know if you need clarification on how I did so)

1 1/2 pounds, 4 3/4 pounds, 2 3/10pounds

1 1/2 = 1  10/20

4 3/4 = 4  15/20

2  3/10 =  2   6/20

1 10/20 + 4 15/20 + 2 6/20 = 7  31/20

7 31/20 = 8 11/20

8 11/20 = 8.55

8.55 / 3 = 2.85

so, the average weight of these packages is 2.85 [pounds]

The required domain of the inverse function is x ≤ 0. Hence option D is correct.

f(x) = -x^2

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is independent variable while Y is dependent variable.

Inverse of function f(x) = -x^2
y = -x^2
x = √-y
Now,
Inverse function of f(x) is √-x
Its domain is define as less than or equal to zero.

Step-by-step explanation:

All-in-one price!

Pay just $100 per month for unlimited use of our great facilities

1. Carlo thinks he will go to the gym about 20 times a month. Which of these options is the least expensive for Carlo? Show how you determined your answer.​

For 20 visits to the gym:

Pay as you go:

20 × $6 = $120

Regular Deal

$50 + 20 × $2 = $50 + $40 = $90

All-in-one price!

$100

Answer:

The best deal is for 20 visits per month is: Regular Deal

To solve this exercise, we apply the rule of three:

Oranges......................Price

 8.................................$4.40

 9.......................................x

We solve as follows:

[tex]\boldsymbol{\sf{x=\dfrac{9\times4.40}{8}=\dfrac{39.6 }{8}=4.9 }}[/tex]

Therefore, 9 oranges would cost $4.9.

The required cost of the amount of 4.95 dollars would be for 9 oranges.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have been given that a grocery store sells a bag of 8 oranges for $4.40.

We have to determine the cost for 9 oranges.

Let's assume x dollars would it cost for 9 oranges.

As per the given condition, we can write the ratio as:

8 oranges : $4.40 = 9 oranges : x dollars

⇒ 8 / 4.40 = 9 / x

Cross multiplication and rearrange the terms of the above equation,

⇒ 8x = 4.40×9

Divide by 8 into both sides of the equation,

⇒ x = (4.40×9)/8

⇒ x = (39.6)/8

⇒ x = 4.95

Therefore, the cost of the amount of 4.95 dollars would for 9 oranges.

[tex]\frac{20}{3}\times\frac{9}{2} \\\\\frac{180}{6}\\\\\ =30[/tex]

Answer:

Hello! the answer to this question is 30.

Step-by-step explanation:

To solve for the quotient, we have to convert the mixed number to an improper fraction:

[tex]6\frac{2}{3} = \frac{6*3 + 2}{3} = \frac{20}{3}[/tex]

When dividing fractions, we have to flip the divisor to its reciprocal. When doing so, the divisor [tex]\frac{2}{9}[/tex] becomes [tex]\frac{9}{2}[/tex].

Now that we have the reciprocal, the operation will change from division to multiplication. We can take the final steps to solve the problem:

[tex]\frac{20}{3} * \frac{9}{2}[/tex]

This leaves you with a result [tex]\frac{180}{6}[/tex]. This can further be simplified by doing 180 ÷ 6 to get 30.

Therefore, the quotient is 30.

C' = C · (1 + r/100)ˣ     (1)

Where:

Please notice that a year consists in four quarters. If we know that C = 1200, r = 5.25 and x = 8, then the current capital is:

C' = 1200 · (1 + 5.25/100)⁸

∠ EGF = 64°

∠ DGE = 26°

Step-by-step explanation:

• ∠ EGF + 90° + 26° = 180°          [angles in a triangle add up to 180°]
⇒ ∠ EGF = 180° - 90° - 26°

⇒ ∠ EGF = 64°

• ∠ DGE + ∠ EGF = 90°                 [as shown in the diagram]

⇒ ∠ DGE + 64° = 90°

⇒ ∠ DGE = 90° - 64°

⇒ ∠ DGE = 26°

The length of the flagpole is x - 5  yards

The area of the flagpole is given as:

Factorize the expression

Area = (x - 5)(x - 5)

Savings with Marvin = $2,595.9

Scholarship amount  = $958.35

Total Scholarship amount received in 2 semesters = $958.35 X 2 = $ 1916.7

There are 19958400 ways if 9 people are selected for positions and if Amy does not want to play then the number of ways will be 1814400 if done through permutations.

Given there are 11 people and nine positions.

We have to find the number of ways in which arrangement can be done if there are 11 people and 9 positions and the number of ways to arrange if Amy doe not want to play assuming the pitcher has already been chosen.

Permutations helps us to know the number of ways an object can be arranged. It is denoted by n[tex]P_{r}[/tex]=n!/(n-r)!

where n is the number of choices available,

r is the choices.

Given that the team has 11 players while there are only 9 positions available, the number of ways is 11[tex]P_{9}[/tex]=11!/(11-9)!

=11!/2!

=19958400

Now Amy does not want to play, therefore the number of ways the remaining people can be arranged in the place of pitcher is 10. Also the positions has also decreased from 9 to 8.

Thus the number of ways in which remaining people can be arranged are: 10[tex]P_{8}[/tex]=10!/(10-8)!

=10!/2!

=1814400

Hence the number of ways in which 11 people are arranged is 19958400 and the number of ways in which the remaining players are arranged is 1814400.
