I can't solve for n, because I don't know what the answer is. 7+n/6 would not make sence.

How would you use a table to graph –3x + 4y = 23?

ANTONII [103]

Answer: you would look for y and then once you have y you put it into desemos which is a graphing app and then you get your line

Step-by-step explanation: you would do +3x on both sides with out doing it to the 4y and the. You would get 4y =23+3x and then you divide everything by 4 even the 4y and then you would get y= 23/4 + 3/4x and then you put it into desemos and it will give you it graphed

An elevator can hold a maximum of 1500 pounds. An average child weighs 75 pounds and the average adult weighs 150 pounds. The el

CaHeK987 [17]

Let's take this problem step-by-step:

Let's first set up some variables:

c: # of children
a: # of adults

Let's examine the information given:

Elevator can hold a maximum of 1500 pounds

⇒ average child is 75 pounds

⇒ average adult is 150 pounds

⇒ therefore: $75c + 150a\leq 1500$

Elevator can fit no more than 14 people

⇒ therefore: $c + a \leq 14$

Let's graph the equations:

$75c+150a\leq 1500\\c+a\leq 14$

⇒ look at the image attached

The point at which the two graphs intersect:

⇒ is the solution that represents the amount of children and adults and

their combine weight

With the horizontal axis being the # of children and vertical axis being the # of adults:

⇒ the solution is 8 children and 6 adults

Answer: 8 children and 6 adults

Hope that helped!

Calculate the amount of money you'll have at the end of the indicated time period, assuming that you earn simple interest.You

patriot [66]

First you need to figure out what 5.4% of 3600 is. So take 3,600 x 0.054. This equals 194.4. You then want to add this to 3,600. This will equal 3,794.4. You then want to do the process again, so the interest this year comes from 3,794.4 x 0.054. This equals about 204.9 (if you can it is 204.8976). Then you want to add that back into 3,794.4 so it will equal about 4,000 (or 3,999.2976) Well now this is a long process, but its the one way I remember how to do it.
