Which of the following is the valid classification of the system given below? $ 7x + 2y = 24
| 2x + 1 = y

Step-by-step explanation:

The system of equation given is a simultaneous equation

7x + 2y = 24 1

2x + 1 = y 2

Rearrange

7x + 2y = 24   *1

| 2x - y = -1 * 2

Use elimination method

7x + 2y = 24

4x - 2y = -2

add

7x+4x = 24-2

11x = 22

x = 22/11

x = 2

Substitute x = 2 into 2

2x+1 = y

y 2(2)+1

y = 4+1

y = 5

Hence x = 2, y = 5

The system of equation is a simultaneous equation

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
