Solve using elimination. 9x + 2y = -5 -9x + y = 11

Mathematics
1 answer:
cupoosta [38]2 years ago

Answer:

(-1, 2)

Step-by-step explanation:

9x+2y=-5

-9x+y=11

If you notice that these two equations can be easily worked out with since 9x (from the first equation) and -9x (from the second equation) can be easily eliminated. So, you will start adding the left numbers/variables from the two equations.

<em>9x</em>+2y=-5

<em>-9x</em>+y=11

2y+y=3y (every variable has a secret/hidden 1)

-5+11=6

3y=6

(divide 6 by 3)

y=2

Replace the value of y into ANY of the equations from the question. (I would be using the second one)

-9x + y = 11

-9x+2=11

(now just do simple algebra)

-9x=9

x=-1

What is the area of the triangle?<br> 10 km<br> 10 km<br> square kilometers
MrMuchimi
The answer is 50 because the formula for the area of a triangle is base x hight x 1/2. So if we plug both the 10s into the formula you get 10x10 which = 100 then divide that by 2 and you get 50. Hope it helps :)

Bella has a credit score of 720. based on the graph, which description most likely explains her score? she pays her bills on tim
Rus_ich [418]

Answer: The correct answer would be that she pays her bills on time and has a lower amount of debt because her credit score are 720 which is considered a good payment point.

Explanation: The correct answer would be that she pays her bills on time and has a lower amount of debt because her credit score is 720 which is considered a good payment point.

Explanation: Credit score is known as CIBIL. By this credit, score banks gauge the creditworthiness of a person. The data listed in our credit report CIBIL generate our credit score.

A person's credit history is submitted to CIBIL by banks and other financial institutions on a particular basis.

For example, if a person has a credit score of 600 then that person cannot be considered a good creditor. In this case, the bank doesn't lend him  .

Mr. Winking is purchasing a car and needs to finance $24,000 from the bank with an annual percentage rate (APR)
babymother [125]

Answer:

<em>The monthly payment is $450.71</em>

Step-by-step explanation:

<u>Financial Computing </u>

Given the loan amount A, the loan term t, and the APR (annual percentage rate), the montly payment is computed as

\displaystyle P=\frac{A}{f}

where f is

\displaystyle f=\frac{1-(1+i)^{-n}}{i}

The provided data is

\displaystyle A=24,000

\displaystyle r=4.8\%

\displaystyle t=5\ years

Since the payments will be made monthly, the values of n and i are:

\displaystyle i=\frac{4.8}{100\times12}=0.004

\displaystyle n=5\times12=60\ months

Calculating f:

\displaystyle f=\frac{1-(1+i)^{-n}}{i}

\displaystyle f=\frac{1-(1+0.004)^{-60}}{0.004}

\displaystyle f=53.25

Now for the payments:

\displaystyle P=\frac{24.000}{53.25}=450.71

\boxed{\displaystyle P=\$450.71}
