Answer:

x=-7,y=2

Step-by-step explanation:

3x - 4y = - 29

and 6x + 5y = - 32

3x - 4y = - 29 (1)

6x + 5y = -32 (2)

equation (1) x 2

6x-8y = -58

equation (2) × 1

6x + 5y = - 32

Substracting → - 13y = -26

13y = 26.

26/ 13 ⇒ y =

⇒ yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy = 2

Putting y = 2 in equation (1), we have

3x - 4(2) = - 20

→ 3x = -29 +8

→3x = -21

→ X = -7

x = - 7

What is the general form of the equation of a circle at (-2,1) and passing through (-4,1)?
Masja [62]
The general form of the equation of a circle with radius ' r '
and centered at  (a, b)  is

                              (x - a)² + (y - b)²  =  r²

I'm pretty sure that your circle is not "at (-2,1)".
I'm going to approach your question assuming that
the circle's center is there.

Since the circle's center is at (-2, 1), the left side of its equation is

                             (x + 2)² + (y - 1)²  =  .

The distance from the center to (-4, 1) is the circle's radius.

That distance is 2, so the right side of the equation is

                                                             4 .

prohojiy [21]

Answer:

if it's true simple interest then each year's interest is the same so interest for one year is a quarter of 241.50 which give you the rate but if each year's interest in left in the account the result will be different , it is a really poorly worded question
