Answer:

8b + 7m + 4n = -10

Step-by-step explanation:

(8b + 8) + (7m – 2) + (4n + 4)

First thing to do is to try to open the brackets, so we have

8b + 8 + 7m - 2 + 4n + 4 =

Next, we collect like terms, so that we have

8b + 7m + 4n + 8 - 2 + 4 =

8b + 7m + 4n + 10 =

And rearranging, we have that

8b + 7m + 4n = -10

Answer:

The inverse of the function f(x) is h(x) = 4x + 48 ⇒ (D)

Step-by-step explanation:

To find the inverse of a function do these steps

Let us do these steps to solve the equation

∵ f(x) = [tex]\frac{1}{4}[/tex]x - 12

→ Replace f(x) by y

∴ y = [tex]\frac{1}{4}[/tex]x - 12

→ Switch x and y

∴ x =  [tex]\frac{1}{4}[/tex]y - 12

→ Add 12 to both sides

∵ x + 12 =  [tex]\frac{1}{4}[/tex]y - 12 + 12

∴ x + 12 =  [tex]\frac{1}{4}[/tex]y

→ Multiply each term by 4

∵ 4(x) + 4(12) = 4([tex]\frac{1}{4}[/tex]y)

∴ 4x + 48 = y

→ Switch the two sides

∴ y = 4x + 48

→ Replace y by h(x)

∴ h(x) = 4x + 48

∴ The inverse of the function f(x) is h(x) = 4x + 48

Answer:

h(x) = 4x + 48 ⇒ (D)

Answer:

[tex]5110, 5111, 5112[/tex]

Step-by-step explanation:

Let [tex]x=[/tex] first consecutive number

[tex]x + (x+1)+(x+2) = 15333[/tex] ([tex]x[/tex] is the first number, [tex]x+1[/tex] would be the second consecutive number of the sequence, and [tex]x+2[/tex] would be the third)

[tex]3x + 3 = 15333[/tex]

[tex]3x = 15330[/tex]

[tex]x = 5110[/tex]

[tex]x+1 = 5110+1[/tex]

[tex]= 5111[/tex]

[tex]x+2 = 5110 + 2[/tex]

[tex]= 5112[/tex]

[tex]\therefore[/tex] the consecutive numbers that sum up to [tex]15333[/tex] are [tex]5110, 5111,[/tex] and [tex]5112[/tex]

Answer: 9/10 of the book.

Step-by-step explanation:

1. Convert all of the fractions to have a common denominator. 6, 5, and 3 are all multiples of 30, so we can convert the fractions to 30ths.

1/6 = 5/30

2/5 = 12/30

1/3 = 10/30

2. Add the fractions together to find the whole amount of the book Joyce has read.

5/30 + 12/30 + 10/30 = 27/30

3. Simplify

27/30 -> 9/10

Step-by-step explanation:

1/6 + 2/5 +1/3=

nominator × with the other fraction denominator+ second fraction nominator × with first denominator / denominator ×denominator =

1/6+2/5= 1×5+2×6/6×5=5+12/30=17/30

17/30+1/3=,17×3+1×30/30×3=51+30/90=,81/90

now let's try to simplify it.

81/90 by 9=9/10

Answer:

A

Step-by-step explanation:

We have the two functions:

[tex]f(x)=3x^2-2x\text{ and } g(x)=9x^2-x+7\\[/tex]

And we want to find:

[tex](f-g)(x)[/tex]

This is equivalent to:

[tex]=f(x)-g(x)[/tex]

Hence, by substitution:

[tex]=(3x^2-2x)-(9x^2-x+7)[/tex]

Distribute:

[tex]=(3x^2-2x)+(-9x^2+x-7)[/tex]

Rearrange:

[tex]=(3x^2-9x^2)+(-2x+x)+(-7)[/tex]

Combine like terms:

[tex]=-6x^2-x-7[/tex]

Hence, our answer is A.

Answer:

Step-by-step explanation:

3x^2 - 2x - 9x^2 + x - 7

-6x^2 - x - 7

Answer:

I would, but the way this is set up is VERY confusing. sorry. maybe try to fix it after copying and pasting to make sure it makes sense.

The evaluated values of the step function for the given input values are as g(-2) = -4, g(2) = 3, and g(5) = 5.

To evaluate the step function g(x) for the given input values, we need to follow the conditions specified for each interval.

Given the step function:

g(x) =

-4, x < -1

-1, -1 ≤ x < 2

3, 2 ≤ x < 4

5, x ≥ 4

Let's evaluate the step function for each input:

g(-2):

Since -2 is less than -1, the condition for the first interval is satisfied. Therefore, g(-2) = -4.

g(2):

Since 2 is less than or equal to 4, the condition for the second interval is satisfied.  Therefore, g(2) = 3.

g(5):

Since 5 is greater than or equal to 4, the condition for the last interval is satisfied. Therefore, g(5) = 5.

Hence, we have:

g(-2) = -4

g(2) = 3

g(5) = 5

639 students attend the highschool

Step-by-step explanation:

Find one-ninth of the students

Since 142 students is two-ninths of students, we would divide

1) 142/2=71

71 students is only one ninth of the students, we need to find 9/9 of students

2) 71*9 = 639

639 students attend school

There is a total of 639 students in the school.

If we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

Let's say the number of students in the school is x

Then,

Since 2/9 of it are in the school band

So,

(2/9) x = 142

x = 639

Hence "There is a total of 639 students in the school".
