What is the product?
(y^2+3y+7][8y^2+y+1)

Answer:

Step-by-step explanation:

  CF + FB = CB

  (7x+4) +(10x-69) = (12x-25)

  5x = 40 . . . . . . . . add 65-12x

  x = 8 . . . . . . . . . . divide by 5

  CF = 7x +4 = 7(8) +4 . . . . use the x value in the expression for CF

The multiplication property of equality was not performed correctly.

Step-by-step explanation:

You are supposed to divide by 3 instead of multiplying by 1/3.

Answer:

Step-by-step explanation:

[tex] - 3 {f}^{3} + \frac{1}{6} MB = D [/tex]

Multiply through by 6 to eliminate the fraction

That's

[tex] - 18 {f}^{3} + MB = 6D[/tex]

Move - 18f³ to the right side of the equation

That's

[tex]MB = 6D + 18 {f}^{3} [/tex]

Divide both sides by M to make B stand alone

That's

[tex] \frac{MB}{M} = \frac{6D + 18 {f}^{3} }{M} [/tex]

We have the final answer as

[tex]B = \frac{6D + 18 {f}^{3} }{M} [/tex]

Hope this helps you

Answer:

R(t)=10+0.50t

Step-by-step explanation:

His rate is based on time, for the first side of the equation.

His beginning pay would be 10, so 10 would act as the y intercept. The rate increases by 0.50, so for every year (t) it would increase by 0.50, why you add 0.50 and multiply by the amount of years he works.

Answer: 3,75 ( 15/4)

Step-by-step explanation:

1/3 (6y - 9) = -2y + 13

6y/3  - 9/3  = - 2y + 13

2y - 2 = - 2y + 13

2y + 2y = 13 + 2

4y = 15

y = 15/4

y = 3,75

Answer:

Step-by-step explanation:

equation given:   a - 2(4 - a) = 7a - 12

distribute and expand the equation

a - 8 + 2a = 7a - 12

combine similar terms:

a + 2a - 7a = -12 + 8

simplify:

-4a = -4

a = -4 / -4

proof that a = 1

a - 2(4 - a) = 7a - 12

1 - 2(4 - 1) = 7(1) - 12

1 - 2(3) = 7 - 12

1 - 6 = -5

-5 = -5  therefore, the a = 1 is correct.

Steps to solve:

a - 2(4 - a) = 7a - 12

~Distribute left side

a - 8 - 2a = 7a - 12

~Combine like terms on the left side

-a - 8 = 7a - 12

~Add 8 to both sides

-a = 7a - 4

~Subtract 7a to both sides

-8a = -4

~Divide -8 to both sides

a = 1/2

Answer:

f^-1(x) = x - 5

Step-by-step explanation:

f(x) = x + 5

y = x + 5

x = y + 5

y = x - 5

f^-1(x) = x - 5

Answer:

f^ -1(x) = x - 5

Step-by-step explanation:

y =x+5

To find the inverse, exchange x and y

x = y+5

Solve for y

Subtract 5 from each side

x-5 = y+5-5

x-5 = y

The inverse is  x-5

Answer:

-11

Step-by-step explanation:

assuming 4x-3 = f(x) and the other equation = g(x)

(4x-3) - (x^2 +2x)

(4(4)-3) - (4^2 +2(4)

(16-3)-(16+8)

(13)-(24)

Answer:

x = 3/2 y + 3

Step-by-step explanation:

2x – 3y = 6.

Add 3y to each side

2x – 3y+3y = 3y+6.

2x = 3y+6

Divide each side by 2

2x/2 = 3y/2 + 6/2

x = 3/2 y + 3

3 / (4/9)

First, let's multiply the top and bottom by 9 to get rid of the fraction in the denominator.

27 / 4 is the final answer.

Answer:

31/9

Step-by-step explanation:

3 4/9 as an improper fraction is 31/9.

We get our answer by multiplying the denominator of the mixed numbers by its whole number and adding that answer to its numerator. We get 31, and we put that over the denominator.

3 4/9

9x3=27

27+4=31

31/9

Answer:

[tex] - 2 - 7 = 3v[/tex]

or,

[tex] - 9 = 3v[/tex]

or,

[tex] - 9 \div 3 = v[/tex]

or,

[tex] -3 = v[/tex]

or,

[tex]v = - 3[/tex]

Answer:

-6m-12

Step-by-step explanation:

-(2m-7)-(3+4(m+4)) =

-2m+7-(3+4m+16)=

-2m+7-(19+4m)

-2m+7-19-4m

-6m-12

OR:

-m-2 ( if you divide by 6 as a common factor)

Multiply both sides by negative four to get rid of the fraction

Answer:

false

Step-by-step explanation:

if you simplify you get 5x+4=5x-10, which is false

Answer:

False

Step-by-step explanation:

Step 1:

4x - 3 + x + 7 = 5x - 10

Step 2:

5x - 3 + 7 = 5x - 10

Answer:

5x + 4 ≠ 5x - 10

Answer:

Between $59.50 and $61.50

Step-by-step explanation:

Since this is about, we have to round the numbers.

85.58 is rounded to 86

24.98 is rounded to 25

2.49 is rounded to 2.50

Therefore:

86 - 25 - 2.50 = 59.50

So the correct answer is #3

Answer:x=-4

Step-by-step explanation:

move 5x to the other side by cancelling it out with -5x

that causes it to be 6-6x=30

move 6 to other side by cancelling out with -6

causes it to be -6x=24

divide by -6 to get x alone

x=24/-6

answer is -4 when reduced

The solution to the equation 6 - x = 5x + 30 is x = -4.

To solve the equation 6 - x = 5x + 30,  follow these steps:

Start by combining like terms on each side of the equation:

6 - x = 5x + 30

Rearranging the equation:

6 - 30 = 5x + x

-24 = 6x

Divide both sides of the equation by 6 to isolate the variable x:

-24/6 = 6x/6

-4 = x
