Answer:

(6,17)

Step-by-step explanation:

2x+5=3x-1

-3x        -3x

-5      -5

-x=-6

^divided by -1 on both sides

x=6

y=2x+5

y=(2)(6)+5

y=17

9. YOU BE THE TEACHER Your friend
Crank

Answer:

Step-by-step explanation:

Yes, it's reasonable.

What you are doing is solving the question by rounding. You come up with an answer. Suppose you loose the decimal somewhere and you get 0.36? Is that reasonable? Do you just write the answer in the provided blank and move on. What now?

You get it wrong?!!

But your estimate should be about 9/3 = 3. Now you look at your calculator with great misgivings, because it made a mistake. Did it or did you? Well ultimately you did, but you have to blame something. So the calculator takes the heat.

Who  knows? Maybe the decimal doesn't work. It's stuck or something. In any event you should be aware that there's no way the answer could be 0.36 when you estimate it to be 3.

Someone help I don’t understand
Rina8888 [55]

Answer:

a)C

b)E

Step-by-step explanation:

a) You have to pick a vowel. There are three vowels and a total of 6 letters so it is 3/6 so the answer is C

b) Picking a card that is not T. None of the 6 letters are T so the probablity of picking a card with no T is 1. So the answer is E.

Say that you (or your parents) are purchasing a used car for $19,850. The sales tax is 7.5%, the down payment is $1,000.00, and
IgorLugansk [536]
We are NOT told  1) the finance charge and 2) the amount of time
<span> <span> 19,850.00 <span> Car Price
+1,488.75 Sales Tax </span> <span>
</span><span> -1,000.00 Down Payment
</span> 20,338.75 </span> </span> This is the amount being financed

Using a loan calculator http://www.1728.org/calcloan.htm
We see that if the loan is for 9.382% and it is for 5 years,
Then the monthly payment is $425.98
We will make 60 (12 months * 5) monthly payments resulting in a total loan cost of 425.98 * 60 =
  <span> <span> 25,558.80 </span> </span> Total Loan Cost
-20,338.75  Money Being Financed

   5,220.05  Five Year's Interest
********************************************************************
THIS ISN'T EXACTLY RIGHT - SCROLL TO THE BOTTOM
So, 5,220.05 / 60 = Interest Paid each month.
= $87.00

So,
425.98
 -87.00
<span> <span> 338.98 </span> </span> Each month goes toward the principal.
******************************************************************************************
Although, the monthly payment remains exactly the same each month, the amount going toward interest and the amount going to equity (what you own), changes drastically each month.
See the mortgage calculator
http://www.1728.org/mortmnts.htm

So, your first payment, of 452.98 pays for $159.02 in interest and $266.95 in principal.
