SOMEBODY PLEASE HELP ME THIS IS A TEST QUESTION.The population of bacteria doubles every hour. At 9 AM. The population is 12 bacteria. The function P (t)=12•2^t models the bacteria population tea hours after 9 AM what is the value of P (5) what does it represent in context

Answer:

Yes , i agree with Noah that the equation would be 3(x + 7) = 57

Step-by-step explanation:

P.S - The exact question is -

To find  - Noah writes the equation 3 (x+7)=57 to represent the situation.

               DO YOU agree with him? Explain your answer.

Proof -

Yes , i agree with Noah

Because in the figure we can see that there is x written 3 times and 7 written 3 time and whole the values is equal to 57 .

Because 57 is divided into x 7 x 7 x 7

∴ we can write it as

3 times x + 3 times 7 = 57

⇒3(x) + 3(7) = 57

⇒3(x+7) = 57

Ans Noah give the same equation 3 (x+7)=57

So, I agree with Noah.

Answer:

[tex] - 2x + 28[/tex]

Step-by-step explanation:

1) Expand by distributing terms.

[tex] - 2x - 2 \times - 14[/tex]

2) Simplify 2 × -14 to -28.

[tex] - 2x - ( - 28)[/tex]

3) Remove parentheses.

[tex] - 2x + 28[/tex]

Therefor, the answer is - 2x + 28.

Answer:

Step-by-step explanation:

A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line).

Answer:

n = 14

Step-by-step explanation:

[tex]5^n = 5^{11} * 5^3[/tex]

simplify the right side

[tex]5^n = 5^{14}[/tex]

Then you can easily see that

[tex]n = 14[/tex]

Answer:

n = 14

Step-by-step explanation:

[tex]a^{x}*a^{y}=a^{x+y}\\\\5^{n} = 5^{11}*5^{3}\\\\5^{n} = 5^{11+3}\\\\5^{n}=5^{14}\\\\[/tex]

n = 14

Answer:

100.44

Step-by-step explanation:

8%= 0.08

0.08*93 = 7.44

93+7.44 = 100.44

Answer:

100.44

Step-by-step explanation:

0.08 x 93 = 7.44

93 + 7.44 = 100.44

Answer:

4,0

Step-by-step explanation:

Find where the two lines intercept at.

They both intercept at 4,0

Answer and Step-by-step explanation:

The solution is (4, 0)

This is because the graphs intersect at this point, which would be their solution.

Answer:

$44.44444444

Step-by-step explanation:

So as per question employees get 10% discount of the discounted price. So our equation would be considering discounted price = x

=> x- 10x/100 = 40 => 100x-10x/100 = 40 => 90x = 4000 => x= $44.4444

Answer:

youve got the answers?

Step-by-step explanation:

Answer:

(-5, -1)

Step-by-step explanation:

When two lines intersect, their x and y values are equal. So,

x = 3y - 2 must equal -7 - 2y = x

x = 3y - 2 = -7 - 2y = x

Let's look at the two middle equations and solve for y.

3y - 2 = -7 - 2y

Add 2y to both sides

5y - 2 = -7

Add 2 to both sides.

5y = -5

y = -1

Now, let's find x. You can use either equation for this step.

When y = -1, then 3y - 2 =

(3)(-1) - 2 = -3 - 2 = -5

So, x = -5, and y = -1

Thus, the answer is (-5, -1)

Answer:

Step-by-step explanation:

a)  looks like about 180  ( by the graph)

b)  February was the only month where the average was about 70

c) yes, b/c this graph has months along the bottom,  as the independent variable and the rain fall in each as the dependent so the amount of rain is a function of each month

D. 45/2 and (1)

A. 89/2 and ( 18 )

Step-by-step explanation:

ap3x

Answer:

19 h

Step-by-step explanation:

The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.

The angle of C is 115 because it is a supplementary angle. A supplementary angle is an angle that has two angles with a sum of 180 degrees and 180 – 65 = 115
