Which function represents the situation?
O f)=x+ 1 +2
O f)=(x-1 +2
O ) = 2(x+ 1) +2
O f)= 2(x- 1 +2

Answer:

It is -7.

Step-by-step explanation:

Since x = -1, we can replace the x with -1 to get: -3 - 4 which is -7.

Answer: The answer is -7 for #11

Step-by-step explanation:f(x) = 3x - 4

f(x) = 3(-1) - 4 plug in -1 in x

-3-4 subtract both -3 and 4

Answer:

462.5 pages

Step-by-step explanation:

You find out how many books she reads in 1 day then you can multiply it by 5 to get 5 days.

If she reads 185 in 2 days. Divide 185 by 2 to get 1 day.

185/2 = 92.5 pages

Now multiply 92.5 by 5 to get how many pages she read after 5 days.

92.5 x 5 =    462.5 pages

Answer:

Step-by-step explanation:

The side lengths are 1/4 of the perimeter, so we can say ...

  the sum of side lengths is 68 ft/4 = 17 ft

  the difference of side lengths is 12 ft/4 = 3 ft

Using x to represent the side length of the smaller square, we have ...

  x + (x +3) = 17 . . . . . . the larger square has side length x+3

  2x = 14 . . . . . . . . . subtract 3

  x = 7 . . . . . . . . divide by 2

The side lengths of the squares are 7 feet and 10 feet.

By solving a simple quotient with the mixed numbers/fractions, we will see that they made 2 batches.

We know that the factory uses 3/4 of a barrel for a batch of granola bars.

In this case, we know that yesterday they used (1 + 1/2) barrels of raisins, to see how many batches of granola bars they made, we need to take the quotient between the total amount used and the amount needed for a single batch.

N = (1 + 1/2)/(3/4)

The quotient can be written as:

N = (1 + 1/2)*(4/3) = 4/3 + 4/6 = 4/3 + 2/3 = 6/3 = 2

They made 2 batches.

Answer:k = 2/3

Step-by-step explanation:

When a variable y directly relates to another variable x, we can say:

y=kx

Given the equation, we can say

3y=2x

y= 2x/3

Putting the value of y from above discussion

kx = 2x/3

x is being cancelled on both sides of equation

k= 2/3

Answer: 100 x 2^ t/9

Step-by-step explanation:

The initial population of 100 that doubles in 9 years, gives the

expression for population as; [tex]\underline{ P = 100 \cdot e^{0.077 \cdot t}}[/tex].

Given parameters are;

The time it takes the population to double = 9 years

The initial population count = 100

Required:

The expression that gives the population after t years.

Solution:

The population as a function of time can be expressed as an

exponential function as follows;

[tex]P = \mathbf{P_0 \cdot e^{c \cdot t}}[/tex]

At the start, t = 0, P = 100, we have;

[tex]100 = \mathbf{ P_0 \times e^{c \times 0} }= P_0[/tex]

Therefore;

P₀ = 100

After 9 years, we have;

P = 2·P₀

Therefore;

[tex]2 = \mathbf{ e^{c \times 9}}[/tex]

ln(2) = 9·c

[tex]c = \dfrac{ln(2)}{9} \approx 0.077[/tex]

The function that gives the population is therefore;

Answer:

2/100, -9/2, 7, 11 1/4, 12.7, 41/2, -26.

Step-by-step explanation:

Given,

Points are -26,-12.7,-9/2,2/100,7,11 1/4,41/2

We have to arrange the number according to their distance from 0.

Simplifying Points

= -26, 12.7, -4.5, 0.02, 7, 11.25, 20.5

Now, arranging the number starting from the smallest distance from 0.

0.02, -4.5, 7, 11.25,12.7,20.5,-26

= 2/100, -9/2, 7, 11 1/4, 12.7, 41/2, -26.

Step-by-step explanation:

Step-by-step explanation:

dt=12t+6

Step 1: Add (-1)/2t to both sides.

dt+−12t=12t+6+−12t

dt+−12t=6

Step 2: Factor out variable t.

t(2d−12)=6

Step 3: Divide both sides by (2d-1)/2.

t(2d−12)2d−12=62d−12

t=12/2d−1

Answer:

Answer:

Water cost 2$ you can buy 3 water bottles with 6$

Step-by-step

I did myself

Answer:

one bottle of water is 0.5 dollars. You can buy three bottles of water for $6

Step-by-step explanation:

since 9 divided by 18= 0.5, this is how it goes

18 bottles broken up into sections of one (one bottle in each section)

so you have to break up the dollars into cents to put an equal amount with each bottle. So you get 100 pennies for each dollar. There's only 9 dollars, so you split the pennies (that you broke from the 9 dollars) and put one in each section (each section still has one bottle) so each bottle with get one more penny with every round. The bottles take turns getting pennies. After you do all of them you will get 0.5 dollars for each bottle so that's how much the bottles cost.

The bottles cost 0.5 dollars.

Now we do this with 6 dollars instead of 9. You now know that each bottle cost 0.5 dollars so you have to do this

0.5 x 6 which = 3.

You can buy 3 bottles with $6.
