Which of the following ordered pairs represents the solution to the system given below?
castortr0y [4]
X − 4y = 7
5x + 9y = 6

5x − 20y = 35  //1st * 5
5x + 9y = 6

5x +9y - 5x + 20y = 6 - 35  //2nd - 1st
5x + 9y = 6

29y=-29
5x=6-9y

y=-1  //1st : 29
5x=6-9*(-1)

y=-1
x=15:5 //2nd : 5

y=-1
x=3

check:
for x=3 and y=-1 there is:
x − 4y = 7 is 3 − 4*(-1) = 7 is 7=7 ok
5x + 9y = 6 is 15-9=6 is 6=6 ok

answer: (3;-1) represents the solution.

stich3 [128]
The answer is 8.5% interest compounded daily.

EXPLANATION

Regardless of your rate, the more often interest is paid, the more beneficial the effects of compound interest.

A daily interest account, which has 360 compounding periods a year, in this case, will generate more money than an account with an annual compounding, which has one compounding period per year.

PLEASE HELP !!! - after tip you gave a total of $321.75. If the original price of the meal was $300, what percent tip was applie
yan [13]

Answer: 7.25%

Step-by-step explanation:

There are a few ways to do this, but the easiest might be to set up a proportion:

321.75/300 = x percent/100 percent

Now cross multiply;

300x = 321.75(100) = 32,175

Divide both sides by 300 to solve for x:

300x/300 = 32,175/300

x = 107.25 This means that the tip was 7.25% on top of the $300 meal.
