Answer:

A

Step-by-step explanation:

8x (the babysitter gets paid 8 dollars an hour, and x represents number of hours)

3 (this is the additional tip the babysitter gets; it's not dependent on the number of hours she/he works)

The babysitter will get paid the same despite babysitting two kids- no variable here is dependent on the amount of kids the babysitter babysits.

Answer:

A) 8x + 3

Step-by-step explanation:

The babysitter gets 8 dollars per hours, and x is the hours, so 8x, 8 dollars per hour. She also gets 3 dollars if she gets the children to sleep on time, so add 3. The equation is 8x + 3.

Answer:

true

Step-by-step explanation:

im pretty sure its true

Answer:

actually it's false because to find the mode you find the number that occurs most often. In this case it's 8.

Answer:

Following on from step 3

0 = (x + 1)(x + 3)

equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 3 = 0 ⇒ x = - 3

Substitute these values into either of the 2 equations for the corresponding value of y

using y = 2x + 11

x = - 1 : y = - 2 + 11 = 9 ⇒ (- 1, 9 )

x = - 3 : y = - 6 + 11 = 5 ⇒ (- 3, 5 )

Step-by-step explanation:

The solutions that represents the system of the equation are (- 3, 5 ) and (- 1, 9 )

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

0 = (x + 1)(x + 3)

By equating each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 3 = 0 ⇒ x = - 3

Substitute these values in 2 equations for the corresponding value of y

using y = 2x + 11

x = - 1

y = - 2 + 11 = 9 ⇒ (- 1, 9 )

x = - 3

y = - 6 + 11 = 5 ⇒ (- 3, 5 )

Therefore, the solutions are (- 3, 5 ) and (- 1, 9 )

Answer:

x=12

Step-by-step explanation:

Answer:

x=12

Step-by-step explanation:

multiply both sides by 4 to cancel the fraction 1/4x so you can add them together

so once you multiply both sides by 4 the equation is

2x+20=x+32 so then combine like terms but subtracting x so that's

x+20=32 then minus 20 to solve

x=12
