Solve the following system of equations:
4x + 3y = 17
3x + 2y = 13

ANSWER:

(x,y) = (5,-1)

(5, -1)

Step-by-step explanation:

Solve the system of equations by elimination.

4x + 3y = 17

3x + 2y = 13

Multiply the top equation by -3 and the bottom equation by 4:

-12x - 9y = -51

12x + 8y = 52

Add these together:

-y = 1

y = -1

Plug in -1 as y into one of the equations, and solve for x:

4x + 3y = 17

4x + 3(-1) = 17

4x - 3 = 17

4x = 20

x = 5

So, the solution is (5, -1)

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.
