Answer:
5.38
Step-by-step explanation:
- 145.4 - 140.02 = 5.38
(x-4)•2 < 9
the difference between x and 4 means to subtract
and twice that means to double or times by 2
and all that’s LESS than 9
so the sign opens up towards the 9
Answer:
y = 5
Step-by-step explanation:
1. This line is horizontal, because the y-coordinate never changes.
2. The equation for a horizontal line is y = (y-coordinate)
3. The y-coordinate is always 5, so the equation is y = 5.
Answer:
5x + y = 8
Step-by-step explanation:
Given the equations:
x+3y=10 ____ (1)
2x−y=−1 ____ (2)
Multiply (2) by 2
2(2x - y = - 1) = 4x - 2y = - 2
4x - 2y = - 2 - - - (3)
Add (1) and (3)
4x - 2y = - 2
x + 3y = 10
