Step-by-step explanation:
Direct proportion is when two numbers move in the same direction. If one of the numbers increase, the other number increases and if the one of the numbers decrease, the other number decreases. The magnitude of the movement of the numbers is bounded by a constant
The expression for direct proportion is
y ∝ kx
where k is the constant
let illustrate with an example :
If x = 10
k = 4
y = 10 x4 = 40

Step-by-step explanation:
Q3
Corresponding angles are congruent
- 6x - 11 = 37
- 6x = 11 + 37
- 6x = 48
- x = 8
Q4
Angle2 is complementary with 142 and alternate interior with 2(x + 9)
- 142 + 2(x + 9) = 180
- 142 + 2x + 18 = 180
- 2x + 160 = 180
- 2x = 20
- x = 10
Answer:

The answer is x=6.1 i believe
Answer:
2x+3+5x+6 = 7x+9
Step-by-step explanation:
2x + 3 + 5x + 6
= 2x + 5x + 3 + 6
= 7x + 9
Hope it helps
