What are the coordinates (x, y) at which the graphs of 2x + 3y = 12 and 2x - y = 4 intersect?

Jobisdone [24]

The coordinates (x,y) are (3,2), If the graphs of $2x+3y=12$ and $2x-y=4$ are intersect.

Step-by-step explanation:

The given is,

$2x+3y=12$ .................................(1)

$2x-y=4$ ....................................(2)

Step:1

The values of x and y are obtained by elimination method,

Substrate the equation (1) and (2),

$2x+3y=12$

$2x-y=4$

( - )

Equation becomes,

$(2x-2x)+(3y+y)=(12-4)$

$(0)+(4y)=(8)$

$4y=8$

$y=\frac{8}{4}$

$y=2$

From the equation (1),

$2x+3y=12$

$2x+3(2)=12$

$2x+6=12$

$2x=12-6$

$x=\frac{6}{2}$

$x=3$

Step:2

Check for solution,

$2x-y=4$ ....................................(2)

Substitute the values of x = 3 and y = 2 in above equation,

$2(3)-2=4$

$6-2=4$

$4=4$

Both sides are equal, so the x = 3 and y = 2 is correct answer

Result:

The coordinates (x,y) are (3,2), If the graphs of $2x+3y=12$ and $2x-y=4$ are intersect.

Using technology, determine the present value given that you make monthly payments of $250.00 at 2.3% compounded monthly over a

Marta_Voda [28]

Here is the answer. Since the given amount $250 is compounded monthly over a 5 year period with an interest of 2.3%, here is the answer. First, we get 2.3% of $250 and the answer is $5.75. In a year, there is 12 months. 12 months times 5 years is 60 months. Now we multiply 60 by 5.75 and the answer is $345. Therefore, the present value of $250 is $595. Hope this helps.

The present age of Sita's father is three times of Sita's present age. After 6 years the sum their age will be 69. Find their pr

Papessa [141]

Age of Sita is 14.25 years and her father is 42.75 years

Step-by-step explanation:

Step 1: From given details, let present age of Sita be x and that of her father be 3x.
Step 2: Form equations based on their ages in 6 years. (Given sum is 69)

⇒ (x + 6) + (3x + 6) = 69

⇒ 4x + 12 = 69

⇒ 4x = 57

⇒ x = 14.25

Step 3: Calculate age of Sita's father

⇒ 3x = 42.75
