Answer:

x=1

Step-by-step explanation:

okay for a second i was going to do a huge explanation but i'll do a simple one.

9(1)-8+5(1)= 8(1)-2

9-8+5= 8-2

9-8= 1+5= 6

8-2= 6

so the answer is x=1, just plug in the number and then you can see if you are correct or not, thats the advice i give on doing these kind of equations. Hope this helps :D

The following table shows the number of hours a cleaning company spends cleaning apartments.

mart [117]

First, plot the points in a graph to see the general trend. The independent variable is time. I used MS Excel to plot the points in a graph, as shown in the attached picture.

1. The relationship is linear as shown in the general trend.
2. The relationship presents that as time increases, the number of apartments cleaned also increases. The two variables are directly proportional.
3. The rate of change represents the slope of the line. Choose any two points and find the slope.

m = (6-3)/(2-1) = 3 apartments cleaned/hour

The equation y = 1.55x + 110,419 approximates the total cost, in dollars, of raising a child in the united states from birth to

Andru [333]

Answer:

The correct option is A). $112295.05

Step-by-step explanation:

The equation for approximating the total cost is given to be :

y = 1.55x + 110419 , where x is the annual household's income and y is the total cost in dollars of raising a child in the united states from birth to 17 years

We need to calculate the total cost of raising a child in the united states from birth to 17 years if the annual household's income is given to be $1211

So, for this we will use the given equation and substitute x = 1211 and find the value of y which will be our total cost

⇒ Total cost , y = 1.55 × 1211 + 110419

⇒ y = 1877.05 + 110419

⇒ y = 112296.05 ≈ 112295.05

Hence, The approximate total cost of raising a child from birth to 17 years in a household with a weekly income of $1211 = $112295.05

Therefore, The correct option is A). $112295.05
