Answer:

Don't have the ability to graph here but graph as follows:

X=1, Y=4

X=2, Y=8

X=3, Y=12

etc....etc....etc

Answer:

4 horses

Step-by-step explanation:

There are 2 elephants and 4 horses on one side. On the other, there are 12 horses. You can cancel 4 horses so now it's 2 elephants and 8 horses. To get the first side (2 elephants) to turn into one elephant, you need to divide by 2. So now, it is 1 elephant = 4 horses.

Answer:

4

Step-by-step explanation:

4 because you can write the problem as  2e+4h=12h then you subtract 4h from both sides and get 2e=8h then you divide by 2 to get e=4 so one elephant is as strong as 4 horses

h=horses

e=elephant

Answer:

A. 200

B. Growth

C. 118%

Step-by-step explanation:

Answer:

Initial population size=200

The function represents a growth

Step-by-step explanation:

Equation to calculate population size after time, t

P(t) = 200(1.18)^t

To find initial population size we will take t = 0

P(0) = 200(1.18)^0

      = 200(1)

      = 200

To find that function represent growth or decay

P(1) = 200(1.18)^1

     = 200(1.18)

     = 236

Its means that after a year population increases. Hence, function represent growth.

By what percentage does the population change each year?

(236 - 200 / 200) * 100%

= 235%

Answer:

935 apples

Step-by-step explanation:

927 plus 8 equal 935

The answer is 935

because remove the 92 from 927 you have 8+7

so the equals 15 then add 1 to the 2 and then you have 3 then you have the remaining 5 where you leave in the ones place then you have 935

Answer:

y = 20x

Step-by-step explanation:

y is the total amount that ricky will pay for the CDs.

x is the number of CDs that ricky bought.

so, in this case, if you replace the x by 600 :

y=20 x 600, witch means that the value of y is :

y = 12000 dollars.

Answer: 5,120

Step-by-step explanation:

Your equation is:

v(t) = 320 • 4^t

You are trying to find v(2) so:

t = 2

Plug in 2 for t:

v(2) = 320 • 4²

Solve:

v(2) = 5,120 views

Answer:

-9/3 or -3

Step-by-step explanation:

[tex]Slope= \frac{y_{2} -y_{1} }{x_{2}- x_{1} }[/tex]

Lets start with the y's, substitute:

-6-3=-9

Then the x's, substitute:

5-2=3

Substitute back into the fraction:

-9/3 or

-3

Answer:

m = -3

Step-by-step explanation:

y2-y1

--------

x2-x1

-6-3/5-2

-9/3

-3

Therefore, your answer for slope would be m = -3

Answer:

1. h = 2.4t + 4

2. 4 feet

3. 220 feet

Step-by-step explanation:

1. Write a linear model for the height, h, of the balloon as a function of the number of seconds, s that it has been raising.

Since the balloon rises at a constant rate, we find this rate by using the initial and final values of height and time at 5 seconds and 20 seconds respectively which are 12 feet and 52 feet respectively.

So, rate = gradient of line

= change in height/change  in time

= (52 ft - 16 ft)/(20 s - 5 s)

= 36 ft/15 s

= 2.4 ft/s

Now the equation of the line which shows the height is gotten from

(h - h')/(t - t') = rate

Using h'= 16 feet and t' = 5 s, we have

(h - 16)/(t - 5) = 2.4

h - 16 = 2.4(t - 5)

h - 16 = 2.4t - 12

h = 2.4t - 12 + 16

h = 2.4t + 4

where h is the height of the balloon above the ground and t is the time spent in the air in seconds.

2. What was the height of the balloon initially before the child let it go?

We obtain the initial height of the balloon before the child let go at time, t = 0 the time before the child let go.

So, substituting t = 0 into the equation for h, we have

h = 2.4t + 4

h = 2.4(0) + 4

h = 0 + 4

h = 4 feet

So, the height of the balloon before the child let go is 4 feet above the ground.

3. Use your model to predict the height of the balloon after 90 seconds.

We insert t = 90 s into the equation for h. So,

h = 2.4t + 4

h = 2.4(90) + 4

h = 216 + 4

h = 220 feet

So, the height of the balloon after 90 s is 220 feet above the ground.

Answer:

16/3 or 5.3 recurring

Step-by-step explanation:

-8 times -2/3 is 16/3, and 16/3 is 5.3 recurring

Answer:

yes, no, yes, no

Step-by-step explanation:

the first two are correct, try an example for 2 and 3

b = a - 5 yes

if a = 5 and b = 0

5 - 5 = 0

a = b - 5 no

if a = 5 and b = 0

5 = 0 - 5 which is not true 5 doesnt equal -5

1.) A. 8/9

2.) C. 4/9

3.) B. 7/11

4.) D. 10/3

5.) C. 0.06 (repeating)

Step-by-step explanation:

Answer:

a,b

Step-by-step explanation:

Answer:

Step-by-step explanation:

Based on similar triangle;

14/49 = x+5/9x+1

Cross multiply

49(x+5) = 14(9x+1)

49x + 245 = 126x + 14

49x - 126x = 14 - 245

-77x = -231

x = -231/-77

x = 3

Hence the value of x is 3
