Hey! I was wondering if someone could help me with this problem? (: I started it off but I need help for anyone who can help me thank you!

(-4, 2)

Step-by-step explanation:

5x + 15y = 10 ---› Eqn. 1

5x - 10y = -40 ---› Eqn. 2

Subtract the eqn 2 from 1 to eliminate the x variable

Thus:

25y = 50

Divide both sides by 25

y = 50/25

y = 2

Substitute y = 2 into eqn 1.

5x + 15y = 10 ---› Eqn. 1

5x + 15(2) = 10

5x + 30 = 10

Subtract 30 from each side

5x = 10 - 30

5x = -20

Divide both sides by 5

5x/5 = -20/5

x = -4

Solution would therefore be (-4, 2)

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.
