(those are the answers i got i'm sorry if some of them are not correct but i used a website called mathpapa and its an algebra calculator and works well)
Answer:
train A is 403
and train B is 72
because if the total weight is 479 and train A is heavier than train B with a difference of 403 to get their weights each, you'll say 479( total amount of weight) - 403( the difference) which or = 72...
where you have A as 403 and B as 72

Option A

Check if slope = 2
------------------------------------------------------
y + 2 = 2(x + 3)
y + 1 = 2x + 6
y = 2x + 6 - 1
y = 2x + 5
Slope = 2
Answer: Yes, Slope is 2
------------------------------------------------------
Check if it passed through (2, 3)
------------------------------------------------------
When x = 2
y = 2(2) + 5
y = 9
Answer: No, it does not passed through (2, 3)
------------------------------------------------------
Option B
------------------------------------------------------
------------------------------------------------------
Check if Slope is 2
------------------------------------------------------
y - 3 = 2(x - 2)
y - 3 = 2x - 4
y = 2x - 4 + 3
y = 2x - 1
Slope = 2
Ans : Yes, slope is 2.
------------------------------------------------------
Check if it passed through (2, 3)
------------------------------------------------------
when x = 2
y = 2(2) - 1
y = 4 - 1
y = 3
Answer : Yes, it passed through (2, 3)
------------------------------------------------------
Answer: (B) <span>y – 3 = 2(x – 2)

The solution to the system of equations is (-3, -5) because the point satisfies both equations
<h3>What is a
linear function?</h3>
A linear function is in the form:
y = mx + b
Where m is the slope (rate of change) and b is the y intercept
Line A:
y = x − 2 (1)
Line B:
y = 3x + 4 (2)
Solving both equations simultaneously gives:
x = -3, y = -5
The solution to the system of equations is (-3, -5) because the point satisfies both equations
