Answer:

(- 10, 13 )

Step-by-step explanation:

Given the 2 equations

- 3x + 2y = 56 → (1)

- 5x - 2y = 24 → (2)

Adding the 2 equations term by term eliminates the y- term, that is

- 8x = 80 ( divide both sides by - 8 )

x = - 10

Substitute x = - 10 into either of the 2 equations and solve for y

Substituting into (1)

- 3(- 10) + 2y = 56

30 + 2y = 56 ( subtract 30 from both sides )

2y = 26 ( divide both sides by 2 )

y = 13

Solution is (- 10, 13 )

max found a car he wants to buy that costs $16,000. He can afford to pay $250 a month for the car. His bank offers him a car loa
DochEvi [55]

Max won't be able to afford the payments.

Since Max found a car he wants to buy that costs $16,000, and he can afford to pay $ 250 a month for the car, and his bank offers him a car loan of 7.3%, and the length of his loan should be about 5 years, to determine if he can afford the payments, the following calculation must be performed:

  • (16000 x 1.073 ^ 5) / (5 x 12) = X
  • 22,757.187 / 60 = X
  • 379.28 = X

Therefore, each monthly payment will be $ 379.28, so Max won't be able to afford the payments.

PLEASE HELP!!
trapecia [35]
First, solve for x. Isolate the x. Do the opposite of PEMDAS.

2x + 4 = 8

Note the equal sign. What you do to one side, you do to the other.

subtract 4 from both sides

2x + 4 (-4) = 8 (-4)

2x = 8 - 4

2x = 4

divide 2 from both sides

2x/2 = 4/2

x = 4/2

x = 2

you know you're starting number now: 2

"then add it to two": 2 + 2 = 4
"then add it to ten": 4 + 10 = 14
"then subtract three": 14 - 3 = 11
"then add ten": 11 + 10 = 21

21 is your final answer


hope this helps

3sin²60°+3/4cot²30°-2cosec²60°-3/4tan²30°=19/12{Full process , please^^}​
Tcecarenko [31]

Answer:

3( root 3 /2)^2 + 3/4 (root 3 )^2 - 2(2/ root 3) ^2 - 3/4 (1/root3)^2

= 3 ×3 /4 + 3 × 3 /4 - 2 ×4 /3 - 3/4 × 1/3

= 9/4 + 9/4 -8/ 3 - 1/4

= 9/4 + 9/4 - 1/4 - 8/3

= 17/4 - 8/3

=( 17 × 3 - 8 × 4 )/12

= (54 -32)/12

= 19 /12
