1) Does the point (0,4) make either equation true? Substitute it in and find out.​
Gekata [30.6K]

Answer:

The point (0,4) doesn't make either equation true.

Step-by-step explanation:

Consider the equations.

y=-2x and y=x+3

We need to determine the point (0,4) make either equation true.

Substitute x=0 and y=4 in y=-2x

4=-2(0)

4=0

Which is false.

Substitute x=0 and y=4 in y=x+3

4=(0)+3

4=3

Which is false.

Hence, the point (0,4) doesn't make either equation true.

How do you find the least common multiple of 2 numbers? Preferably using the ladder method
g100num [7]
Hi,
Sorry, I don't use the ladder method, but I can show you how to find the <span>least common multiple of 2 numbers using a different method:
Let's say we are finding the least common multiple of 3 and 9:

3: 3, 6, 9, 12, 15, 18
            --
-------------------------------
9: 9, 18, 27, 36, 45, 54
    --

All I did was list multiples of both the numbers till I found one that was common (however, in the example above, I listed a few extra)

Hope this helped 
:)
