Answer:

The value of [tex]gf\left(-2\right)[/tex] will be:

Step-by-step explanation:

Given the functions

[tex]f(n) = n^2 - 4n + 3[/tex]

[tex]g\left(n\right)\:=\:2n\:-\:1[/tex]

[tex]f\left(-2\right)\:=\:\left(-2\right)^2\:-\:4\left(-2\right)\:+\:3[/tex]

           [tex]=\left(-2\right)^2+4\cdot \:2+3[/tex]

           [tex]=2^2+4\cdot \:2+3[/tex]

            [tex]=2^2+8+3[/tex]

            [tex]=4+11[/tex]

            [tex]=15[/tex]

so

[tex]gf\left(-2\right)=g\left(15\right)[/tex]

             [tex]=2n-1=2\left(15\right)-1=30-1=29[/tex]

Answer:

1.99 * 10^4

Step-by-step explanation:

Here, we want to write the addition in standard form

= (1 * 10^4) + (9 * 10^3) + (9 * 10^2)

= 10,000 + 9000 + 900

= 19,900

so the number in standard form is;

1.99 * 10^4

Answer:

5. a^3 + b^3 = (a+b)^3 - 3ab(a+b)

Step-by-step explanation:

(a+b)^3

= (a+b) (a+b) (a+b)

={(a+b) (a+b)} (a+b)

={a(a+b) + b(a+b)} (a+b)

=(a^2 + ab + ab + b^2) (a+b)

=(a^2 + b^2 + 2ab) (a+b)

=a^2(a+b) + b^2(a+b) + 2ab(a+b)

=a^3 + a^2b + ab^2 + b^3 + 2a^2b + 2ab^2

=a^3 + b^3 + 3a^2b + 3ab^2

=a^3 + b^3 + 3ab(a+b)

(a+b)^3 = a^3 + b^3 + 3ab(a+b)

(a+b)^3 - 3ab(a+b) = a^3 + b^3

a^3 + b^3 = (a+b)^3 - 3ab(a+b)

Answer:

The major weakness of the Articles of Confederation was that it did not allow Congress to tax the nation, which caused debt issues (A).

Explanation:

Not only this but it prevented the Congress from forming a central government that would be capable of ruling the newly formed United States.

Answer:

15 servings

Step-by-step explanation:

total amount of lemonade = 19.64 cups

lemonade per serving = 1.25 cups

total servings = 19.64 cups / 1 .25 cups = 15.712 servings

since you cannot sell a partially full serving, Jessica and Jonathan will only be able to sell 15 servings

in order for them to sell 16 full servings, they need to prepare 20 cups of lemonade (= 20 / 1.25 = 16)

Answer: 240 miles

Step-by-step explanation:

Answer:

Each glass of milk is 9 carbs.

Each snack bar is 19.7 carbs.

Step-by-step explanation:

1. I know that 2 glasses of milk with 3 snack bars is 78 carbs.

The next part of the sentence has two times the amount of milk with the same amount of snack bars for 96 carbs.

Now, I will find the difference in the amount of carbs.

96 - 78 = 18 carbs.

So two glasses of milk = 18 carbs.

18 ÷ 2 = 9 carbs

So, each glass of milk is 9 carbs.

2. Since we know this, we can subtract the amount of carbs from the glasses of milk from the total amount of carbs.

78 - 19 = 59

In the first scenario, there are 59 carbs per 3 snack bars.

To find the amount of each snack bar, divide 59 by 3.

59 ÷ 3 = 19.7 when rounded to the nearest tenth.

Therefore, each snack bar is 19.7 carbs.

Answer:

glass of milk = 9 carbohydrates

snack bars = 20 carbohydrates

Step-by-step explanation:

Let s be snack bars and g be the glasses of milk.

3s + 2g = 78

3s + 4g = 96

-1(3s + 2g) = -1(78)

- 3s - 2g = - 78

- 3s - 2g = - 78

3s + 4g = 96

2g = 18

g = 18/2

g = 9

3s + 2g = 78

3s + 2(9) = 78

3s + 18 = 78

3s = 78 - 18

3s = 60

3s/3 = 60/3

s = 20

Check: g = 9; s = 20

3s + 2g = 78

3s + 4g = 96

3(20) + 2(9) = 78

60 + 18 = 78

78 = 78

3(20) + 4(9) = 96

60 + 36 = 96

96 = 96

So, the solution is g = 9; s = 20

id say 4 google's calculator is a good math helper as well

Step-by-step explanation:

Answer:

y= -4x+-3 = y=-4x-3

The rest are wrong.

Hi there! :)

We are given the slope of the line and its y-intercept.

So, we write the equation in slope-intercept form (y=mx+b)

m is the slope of the line, and b is the y-intercept.

y=mx+b

y=-4x-3

Hence, that's the equation (Option A)

Answer:

The plotted dots connect to create a parallelogram with two sets of parallel lines in the second quadrant

Step-by-step explanation:

This might be a little tricky to explain but I will try my best.

A parallelogram is a four-sided plane rectilinear figure with opposite sides parallel.

The first pair of numbers is in the second quadrant the second set is also in the second quadrant a little bit up and to the right. The third set in the line a little up, the last set is again in the second quadrant and a little further down and near the middle.

Sorry if the answer isn't what you had hoped for, feel free to ask questions about it and I'll explain the best I can.

Answer:-49

Step-by-step explanation:(10,1)= (x,y) so we can see that x=10 and y=1. Now you put them in the equation 1=b+5*10. Then you get 1=b+50 and you put 50 to the left side and it becomes negative. 1-50=b . Therefore b=-49

Answer:

Step-by-step explanation:

y = 5x + b ⇒ b = y - 5x

(10, 1)

b = 1 - 5(10) = 1 - 50 = - 49

b = - 49

Answer: $‭986.47‬

Step-by-step explanation:

The total tuition fee for the year is;

= 13,287.48 - 1,449.84

= $‭11,837.64‬

The payment per month will therefore be;

= ‭11,837.64‬/12 months

= $‭986.47‬

Answer:

The differences between the absolute highest and the absolute  lowest temperatures is 78°.

Step-by-step explanation:

It is provided that:

Compute the differences between the absolute highest and the absolute  lowest temperatures as follows:

[tex]\text{Difference}=|\text{Highest}|-|\text{Lowest}|[/tex]

                [tex]=|105^{o}|-|-27^{o}|\\\\=105^{o}-27^{o}\\\\=78^{o}[/tex]

Thus, the differences between the absolute highest and the absolute  lowest temperatures is 78°.
