Answer:
x + y = 2
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y + 3 = - (x - 5) ← distribute
y + 3 = - x + 5 ( subtract 3 from both sides )
y = - x + 2 ( add x to both sides )
x + y = 2 ← in standard form
Answer:
x = 5
Step-by-step explanation:
5(x + 10) + 2x = 13 + 3(5x - 1)
5x + 50 + 2x = 13 + 15x - 3
7x + 50 = 10 + 15x
50 - 10 = 15x - 7x
40 = 8x
40/8 = x
5 = x
Train B is travelling at the greater speed. If you look at the graph, you can see that after two hours, train B has gone 250 miles, while A has gone only 120.
Answer:
y=x-2
Step-by-step explanation:
In the table, y is always 2 less than x. Therefore, the equation would be y=x-2. Hope this helps!
