Step-by-step explanation:

The domain of the function is the range of x-values, which is -5 <= x <= 5. (D)

Answer: P(x) = 20x - 96,000

Step-by-step explanation:

Cost revenue and profit function.

Cost function;

C(x)= 40x + 96,000

Revenue function;

R(x)= 60x

Profit = Revenue - Cost

P(x) = 60x - (40x + 96,000)

P(x) = 20x - 96,000

Answer:

11

Step-by-step explanation:

1+red/3=4/1 so 1+red=12 so red=11. we should add 11 red counters

Answer:

Add 15 red counters

Step-by-step explanation:

Number of red counter is 1

Number of blue counter is 3

1:3⇒4:1

Now to make ratio reverse you need to add 11 (12-1) more red counters so that ratio becomes

12:3=4:1

hope this helps

Answer:

A) Juan wins the race

B) J(t) = A (t) at (7 minutes, 2 miles)

C) The interval is 7 minutes to 15 minutes

Step-by-step explanation:

a) Juan wins the race

The reason is that the time Juan took to cover the distance of 4 miles is shorter than the time Antonio took

b) J(t) = A(t) at what point

This simply refers to the point at which the two graphs cross over one another

We can see this at the point ; (7,2)

This is; 7 seconds and 2 miles

What this mean is that they both covered 2 miles in 7 seconds

c) interval where J(t) > A(t)

This is the interval at which Juan was ahead of Antonio

Juan was below within 7 minutes

after 7 minutes he picked up

so the interval is 7 minutes - 15 minutes

Answer:

B

Step-by-step explanation:

The angle at the centre is equal to the arc that subtends it , thus

∠ ABC = arc AB = 75° → B

Answer:

Answer of this equation is (x-2)^2/ (X+3)^2

Step-by-step explanation:

x^2-4/X+3 × x-2/ x^2+5x+6

(X+2)(x-2) / X+3 × x-2/ x^2+(2+3)X+6

(X+2)(x-2)/X+3 × x-2/(X+2)(X+3)

(x-2)(x-2)/(X+3)(X+3)

(x-2)^2/(X+3)^2

Answer:

Amphibians! In order for water-dwelling animals to adapt to life on land, many new adaptations had to take place. First, they needed to be able to breathe air instead of obtaining oxygen from water. And fins don't work well as legs! They needed to be able to move around well on land.

What group of animals begins its life in the water, but then spends most of its life on land? Amphibians! Amphibians are a group of vertebrates that has adapted to live in both water and on land. Amphibian larvae are born and live in water, and they breathe using gills. The adults live on land for part of the time and breathe both through their skin and with their lungs as their lungs are not sufficient to provide the necessary amount of oxygen.

There are approximately 6,000 species of amphibians. They have many different body types, physiologies, and habitats, ranging from tropical to subarctic regions. Frogs, toads, salamanders , newts, and caecilians are all types of amphibians.

[tex]100.59\ \text{miles}[/tex]

Step-by-step explanation:

The distance traveled by Dylan every day is 4.79 miles

Let the number of days he went to school be [tex]x[/tex]

Distance traveled by Dylan in a month is given by

[tex]y=4.79x[/tex]

Total number of days Dylan went to school last month is 21

The distance traveled by Dylan last month was [tex]y=4.79\times 21=100.59\ \text{miles}[/tex]

Answer:

I think 100$

Step-by-step explanation:

I can't be to sure

Answer:

900 dollars

Step-by-step explanation:

This is pretty easy

We know 10 percent off

so we can make an equation

0.1x=90

Then just solve

x=900

So 900 dollars

We can check by use finding 10 percent of 900

which is 90

SO its correct

Answer:

A' = (-1, -1)

Step-by-step explanation:

Rule for the dilation of any point A(x, y) about the origin by a factor of k is given by the rule,

A(x, y) → A'(kx, ky)

From the graph attached,

Coordinates of point A are (-3, -3) and it is dilated by a scale factor of [tex]\frac{1}{3}[/tex] about the origin then the coordinates of the image point A' will be,

A(-3, -3) → [tex]A'(-3\times \frac{1}{3},-3\times \frac{1}{3})[/tex]

             → A'(-1. -1)

Therefore, coordinates of A' = (-1, -1) is the answer.

Answer:

f(3) = 16

Step-by-step explanation:

To evaluate f(3), substitute x = 3 into f(x), that is

f(3) = 25 - 3² = 25 - 9 = 16

Answer: See explanation

Step-by-step explanation:

Alyssa starts with $40 and saves $10 each week. This can be written as:

= 40 + 10x

Bill has $24 and saves $12 each week. This can be written as:

= 24 + 12x

where, x = number of weeks

a. Bill will never have more money than Alyssa.

False.

From the 9th week, Bill will have more money than Alyssa. To check goes below.

Alyssa = 40 + 10x = 40 + 10(9) = 40 + 90 =$130

Bill = 24 + 12x = 24 + 12(9) = 24 + 108 = $132

b. Bill's savings can be represented by the equation = 12 + 24 where x is the number of weeks and y is his savings.

False.

Bill savings can be represented by:

= 24 + 12x

where, x = number of weeks

c. Alyssa and Bill will have the same amount of money at Week 6.

False.

Alyssa = 40 + 10x

= 40 + 10(6)

= 40 + 60

= $100

Bill = 24 + 12x

= 24 + 12(6)

= 24 + 72

= $96

4x+y=9

4(2)+(1)=9

8+1=9

9=9

It is a solution

Answer:

9=9

Step-by-step explanation:

Solution:

x = 2

y = 1

4x+y=9

4(2) + (1)=9    (here 4 and 2 are multiplying with each other, so 4x2= 8)

8+1=9

9=9

Answer:

b, the points can't be on the same point as the slope

Answer:

1800

Step-by-step explanation:

suppose the initial cost to be x

it was increased by 6.5%

so, since the price increased is 117

117=6.5% of x

117=(6.5/100) . x

117 . 100=6.5 x

x=11700/6.5

x=1800
