Y = 3x - 1 ---- (1)
x - y = -9 ---- (2)
From Equation 2:
x - y = - 9
x + 9 = y
y = x + 9 --- (2a)
(1) - (2a):
0 = 3x - x - 1 - 9
0 = 2x - 10
2x - 10 = 0
2x = 10
x = 5 ---- sub into (1)
y = 3(5) - 1
y = 15 - 1
y = 14

Step-by-step explanation:
Answer: Correct Answer is 4th option , 28
Step-by-step explanation:
We can find the measure of the angle using the tangent.
We know, tangent of an angle = Perpendicular/Base, corresponding to that angle.
So, Tan of angle T = RG / RT
or, Tan of angle T = 8/15
or, angle T = tan inverese of 8/15
or, angle T = 28.07
So, angle T rounded to nearest degree = 28
Hope this helps.

60°; all of of the angles of a triangle add up to 180° so 180 divided by 3 equals 60°.
Answer: -5 1/2, -5.2, -5, -5/2, 5.5
We can visualize a number line to see where these numbers would rank.
