Value of x: 2.5
Value of y: -0.5
-------------------------
To find x:
x + 1 = 3x - 4
-x -x
1 = 2x - 4
+4 +4
5 = 2x
-- ---
2 2
2.5 = x
Check:
2.5 + 1 = 3(2.5) - 4
3.5 = 7.5 - 4
3.5 = 3.5
To find y:
3y = 5y + 1
-5y -5y
-2y = 1
--- ----
-2 -2
y = -0.5
Check:
3(-0.5) = 5(-0.5) + 1
-1.5 = -2.5 + 1
-1.5 = -1.5
Three million three hundred eighty-eight thousand one hundred ninety-eight - 3388198

Answer: the restrictions on the domain of (u°v) (x) are x ≠ 2 and which v(x) ≠ 0.
Justification:
1) the function (u ° v) (x) is u [ v(x) ], this is, you have to apply first the function v(x) whose argument is (x), and later the function u (v(x) ) whose argument is v(x).
2) So, the domain of the composed function (u ° v) (x) has to take into account the values for which both functions are defined.
3) The domain excludes x = 2 because v(x) is not defined for x = 2.
4) And the domain must also exclude v(x) = 0 because u is not defined for v(x) = 0.
5) So, in conclusion, the domain is all the real values except x = 2 and the x for which v(x) = 0.
Therefore the resctrictions are x ≠ 2 and v(x) ≠ 0
Answer:
J' = (-2, 4)
Step-by-step explanation:
The transformation for 270° counterclockwise rotation about the origin is ...
(x, y) ⇒ (y, -x)
The point J is (-4, -2), so the point J' is ...
J' = (-2, -(-4))
J' = (-2, 4)
