13) BCA = 90*
CAB = tan^-1 (10/13)
= 37.57*
ABC = tan^-1 (13/10)
= 52.43*
14) ACB = 90*
CBA = tan^-1 (2/3)
= 33.69*
BAC = tan^-1 (3/2)
= 56.31*
D. (2,3)
Explanation:
We already know that x=2, so of we plug in 2 for x, we should get the y value.
Once we plug in 2 for x we should get the equation:
2(2)+3y=13.
Simplify that and we get:
4+3y=13.
Subtract 4 from both sides and we get:
3y=9.
Divide both sides by 3 and we get:
y=3.
This means that your ordered pair should be (2,3).
Hope this helps :)

Answer:
Step-by-step explanation:
calculate x for this equation
f(x) = -5 : -4x +2 = - 5 so : -4x =-7 x = 7/4
f(x) = 2 : -4x +2 = 2 so : -4x =0 x = 0
f(x) =6 : -4x +2 = 6 so : -4x =4 x = -1
f(x) = 18 : -4x +2 = 18 so : -4x =16 x = - 4
the domain is : D = {7/4, 0, -1, -4}
