Answer:

B (-5, -2, 3, 8)

Step-by-step explanation:

Remember this because you'll probably need it

The range consists of all the y-values that make up a function. Since all of the y-values are [-5, -2, 3, 8], the answer is B

Answer:

There are 15 girls

Step-by-step explanation:

Given:- Ratio of boys to girls = 5:3

And, the number of boys = 75

let the girls be 5x and boys be 3x

so, 5 × 75 { given }

x = 75/5 = 15

6x= 6 × 15 = 90

6x/6 = 90/6 = 15

Answer:

y = 2x² - 24x + 76

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

here a = 2 and (h, k ) = (6, 4 ) , then

y = 2(x - 6)² + 4 ← in vertex form

expand factor using FOIL

y = 2(x² - 12x + 36) + 4 ← distribute parenthesis by 2

y = 2x² - 24x + 72 + 4

y = 2x² - 24x + 76 ← in standard form

The perimeter of his house: 256 ft

Step-by-step explanation:

length of living room = 2 x length of garage

                              =2 x 8 ft

                              =16 ft

width of living room  = 2 x width of garage

                             = 2 x 10 ft

                             = 20 ft

daniel house length =  3 x length of L.R

                            = 3 x 16 ft

                            =48 ft

daniel house width   = 4 x width of L.R

                             = 4 X 20 ft

                            = 80 ft

preimeter of rectangle = 2[l + b]

                               = 2[ 48 +80 ]

Tn= -9+(n-1)×3

Step-by-step explanation:

d= t2-t1 =t3-t2....

=-6-(-9)=3

We realize that this is an arithmetic sequence

Therefore Tn= a + (n-1)d, whereby a if the first term= - 9,d=3

Tn=-9+(n-1)×3

Answer:An=-9+3(n-1)

Step-by-step explanation:

First, find the common difference (the amount you are adding each time). You can find this by taking the second term and subtracting the first term.  Now, identify the first term.  This is the first number in your list.  Finally, plug the first term in for A1 and the common difference in for d in the equation an=a1+d(n-1)  Note: Leave the variable n as part of the equation.

The time Akeem runs on days must be 9.3 minutes or less than 9.3 minutes if the mean running time for 7 days must be 9 minutes or less.

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

We have:

Akeem will record the time it takes him to run 1 mile each day for 7 days. In order to meet his fitness challenge, his mean running time for 7 days must be 9 minutes or less.

Here we are assuming that it is required to find the time Akeem runs on the 7th day.

Let's suppose Akeem runs x minutes on the 7th day.

Mean running time ≤ 9

The mean:

[tex]\dfrac{(9.4+9.0+9.1+8.9+8.5+8.8+x)}{7} \leq 9[/tex]

[tex]\dfrac{(53.7+x)}{7} \leq 9[/tex]

53.7 + x ≤ 63

x ≤ 9.3 minutes

Thus, the time Akeem runs on days must be 9.3 minutes or less than 9.3 minutes if the mean running time for 7 days must be 9 minutes or less.

The number of the possible combinations from rolling a sixteen-sided and a twenty-sided dice at the same time is 320.

The arrangement of the different things or numbers in a number of ways is called the combination.

The possible outcomes for dice with 16 sides:-

{ 1,2,3,4,5,6,...............16}

The possible outcomes for dice with 20 sides:-

{ 1,2,3,4,5,6,...............20}

So the number of the possible pairs will be:-

The division equation that has a quotient of 13 is 1/1/13 = 13

The given parameters are:

A division equation is represented as:

Dividend/Divisor = Quotient

Substitute 13 for the Quotient

Dividend/Divisor = 13

Recall that:

Unit fraction = 1/n

So, we have:

Dividend/1/n = 13

Let n = 13.

So, we have:

Dividend/1/13 = 13

This gives

13 * Dividend = 13

Divide both sides by 13

Dividend = 1

So, we have:

1/1/13 = 13

y-intercept: 3 which is also written as (0, 3)

[Solution One]

   We can find the answer by graphing. See attached. The points at which the line intersects the different axes is the answer.

[Solution Two]

   We can solve by plugging into the equation. We will do this by setting the other variable, the one we aren't solving for, to 0.

For the x-intercept:

   y = −13x + 3

   (0) = −13x + 3

Answer:

Hamburger is 320 calories. Pack of french fries is 280 calories

Step-by-step explanation:

Represent Hamburgers as H and pack of French Fries as P then set up the equations

5H+2P=2160

4H+5P=2680

Multiply the first equation by 5

25H+10P=10,800

Multiply the second by 2

8H+10P=5360

Subtract the first equation by the second

25H+10P=10,800

-

8H+10P=5360

=

17H=5440

H=320

One hamburger is 320 calories.

Plug in 320 for H

General form of a linear equation:  [tex]y=mx+b[/tex]

(where m is the slope and b is the y-intercept)

A linear equation has a constant rate of change which is represented by the slope (m).  It is the rate at which one quantity is changing with respect to another quantity.

Part (a)

Given equation:  [tex]y=-9x+55000[/tex]

where:

The rate of change (slope) is -9 and represents that for every 1 mile driven, the value of the car decreases by $9.

The initial value is the y-intercept (b) as this is the value when x = 0.

Therefore, the initial value of car is $55,000.

Part (b)

To find the number of miles at which the car be valued at $35,002, set the equation to $35,002 and solve for x:

[tex]\implies -9x+55000=35002[/tex]

[tex]\implies -9x=35002-55000[/tex]

[tex]\implies -9x=-19998[/tex]

[tex]\implies x=\dfrac{-19998}{-9}[/tex]

[tex]\implies x=2222[/tex]

Therefore, the car will be valued at $35,002 after 2,222 miles.

Given equation:  [tex]y=0.39x+2.55[/tex]

where:

The rate of change (slope) is 0.39 and represents that for every increase of 1 oz of weight in carrots, the price of the carrots increases by $0.39

The initial value is the y-intercept (b) as this is the value when x = 0.

Therefore, the initial cost of the carrots is $2.55.

Part (b)

To find the weight of carrots you can buy for $6.06, set the equation to $6.06 and solve for x:

[tex]\implies 0.39x+2.55=6.06[/tex]

[tex]\implies 0.39x=6.06-2.55[/tex]

[tex]\implies 0.39x=3.51[/tex]

[tex]\implies x=\dfrac{3.51}{0.39}[/tex]

[tex]\implies x=9[/tex]

Therefore, you can buy 9 oz of carrots for $6.06

Part (c)

To find out how much it costs to buy 21 oz of carrots, substitute x = 21 into the equation and solve for y:

[tex]\implies y=0.39(21)+2.55[/tex]

[tex]\implies y=10.74[/tex]

Therefore, it costs $10.74 to buy 21 oz of carrots.
