Answer:

B. f(x) = 3x + 5

Step-by-step explanation:

Initial amount of bacteria N0 = 5 bacteria's

If the triple every hour,

The increase in bacteria in the colony after x hour will be 3*x =3x

x is the amount of hour.

Total amount of bacteria in the colony after x hour will be N0 + 3x

Let f(x) be the total amount of bacteria in the colony after x hour

f(x) = N0+3x

Since N0 = 5

f(x) = 5+3x

Re-arrange

f(x) = 3x + 5

Hence an explicit formula to model the equation is f(x) = 3x + 5

Given expressions;

     f(x) = x² + 6x + 7

     g(x) = 8x² - 2

     h(x) = 3x + 4

     k(x) = x - 3

Find  f(2) - g(2). k(2)

f(2) = 2² + 6(2) + 7 = 23

g(2) = 8(2)² - 2 = 30

k(2) = 2 - 3 = -1

Now,  f(2) - g(2). k(2) = 23  - (30)(-1)

                                  = 53

The solution to the problem is 53

Answer:

Brandon is correct.

Step-by-step explanation:

Initially, there id 4 pints of green paint in the bucket.

As the green paint is made from equal amounts of yellow paint and blue paint, so, the initial amount of yellow and blue paint in the bucket  is 2 pint each.

Let x pints of yellow paint to be added to the bucket to make the desired shade.

Total amount of the paint in the bucket, after addition of [tex]x[/tex] pints of yellow color become [tex]4 + x[/tex] pint, in which the ampunt of yellow color is [tex]2+x[/tex] pints.

As, the ampunt of yellow color is 80% of the total amount of the mixture, so

[tex](4+x)\times 80\%=2+x[/tex]

[tex]\Rightarrow (4+x)\times \frac{80}{100}=2+x[/tex]

[tex]\Rightarrow 4(4+x)=5(2+x)[/tex]

[tex]\Rightarrow x=6[/tex]

So, 6 pints of yellow paint to be added to the bucket to make the desired shade.

Hence, Brandon is correct.

Answer:

Brandon is correct that the mixture needs 6 more pints of yellow paint.

50%(4 pints) + 100%(x pints) = 80%(4 + x pints)

2 + x = 3.2 + 0.8x

0.2x = 1.2

x = 6

Bianca is correct because adding the 6 pints won't fit in the gallon bucket. Adding 6 pints of yellow to the original 4 pints of green is 10 pints, which will not fit in the 1-gallon bucket. (1 gallon = 8 pints)

Answer:

highlight input and output.

Step-by-step explanation:

sorry if this doesn't work. i'm not 100% sure but its worth a try.

Step-by-step explanation:

Non-proportional relationships affect these representations because the y-intercept in the graph will no longer be zero, the ratios in the table will not be proportional, and the equation will be affected because the number will be added or subtracted which is represented by b.

Proportional relationships are relationships between two variables where their ratios are equal. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other.

That constant is know as the "constant of proportionality".

Step-by-step explanation:

80- 34.34 = 45.66

45.66 ÷ 7.61 = 6

Answer:

6 pounds of coffee

Step-by-step explanation:

80 ÷ (7.61p) = 34.34

80 - 34.34 = 45.66

45.66 ÷ 7.61 = 6

6 pounds of coffee

The answer is x+10 divided by -3.

When we take the absolute value of a number, we always end up with a positive number (or zero). Whether the input was positive or negative (or zero), the output is always positive (or zero). For instance, | 3 | = 3, and | –3 | = 3 also.

The solution of the given inequalities is y>-3 and y>4 respectively.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

Given inequalities are -3y > 9 and 2y - 6 > 2.

-3y > 9

y > -9 / 3

y > -3

The second inequality will be calculated as,

2y - 6 > 2

2y > 2 + 6

2y > 8

y > 4

Therefore, the solution of the given inequalities is y>-3 and y>4 respectively.

you don't want to exceed 525, so you set the inequality to be

[tex]525\geq 175+85x[/tex]

we can think of the max as just

[tex]525=175+85x[/tex]

solve for x

[tex]85x=350[/tex]

[tex]x=4ish[/tex]

(note: always round down so that you don't exceed the max. ex. you could round to 4.11 instead of 4.12. x=4.12 would give you a value greater than 525)

Explanation:

5 & 1/3 is the mixed number with 5 as the whole part and 1/3 as the fractional part

Let's convert to an improper fraction

5 & 1/3 = 5 + 1/3

5 & 1/3 = 5*(3/3) + 1/3

5 & 1/3 = 15/3 + 1/3

5 & 1/3 = (15+1)/3

5 & 1/3 = 16/13

The mixed number 5 & 1/3 is equivalent to the improper fraction 16/3

-------------------

Each serving is 7/8 cup

x of these servings is (7/8)x

x is the number of servings in a full container, so

(7/8)x = 16/3

x = (16/3)*(8/7)

x = (16*8)/(3*7)

x = 128/21

x = 6.0952 approximately

x = 6 when rounding to the nearest whole number

So the container is about 6 servings.

he should use 3.5 cups of milk.

bc three goes into seven 2 1/3 times.

and 1/3 of 1.5 is 0.5

since 3 goes into 7, 2 times, he uses 3 cups of milk, and sinze 1/3 of 1.5 is 0.5, add them together and you get 3.5

Answer:

y = 1 cm

x = 7 cm

Step-by-step explanation:

x = 3y + 4

perimeter = 2 * ( y + x ) = 16

x + y = 8 by using x = 3y + 4

y + 3y + 4 = 8

4y = 4

y = 1

1 + x = 8

x = 7

y = 1 cm

x = 7 cm

Step-by-step explanation:

If you were to divide 7 by 14 you would get 0.5. The reason as to why you would divide 7 by 14 is because if she eats twice a day that would be 7 more times then if she were to be fed once a day. So if you  were to feed her twice a day that would be 14 times a week.

Don't think this helped at all but I tried my hardest, sorry if you get your problem wrong. Hope you have a good day :D
