Answer:
One solution (-1,2)
Step-by-step explanation:
Since these two linear equations have different slopes, different y-intercepts, and are indeed linear, these equations will only have one crossing when graphed, and hence one solution.
To find that solution, we can simply set the equations equal to each other.
y = -x + 1
y = 2x + 4
-x + 1 = 2x + 4
-3 = 3x
-1 = x
Now plug that value back into one of the equations:
y = -x + 1
y = -(-1) + 1
y = 2
So now you know the crossing for these two equations occurs at (-1,2).
Cheers.
Answer:
25
Step-by-step explanation:
Since y varies inversely with x, the relation between y and x will be:
Introducing the proportionality constant, we can write:
Using the first set of given values of x and y, we get:
This means, the relation between y and x is:
We have to find y if x = 20. Using this value in above equation, we get:
Thus y would be 25 if x is 20.

Step-by-step explanation:
Answer:
-3/12
Step-by-step explanation:
In negative numbers, it's basically the opposite of regular numbers.
Let's explain negative numbers as debts. Let's say you owe a friend 1 dollar, and another 2 dollars. In a sense, you'll have -1 dollars, and -2 dollars. Which one is the greater number? It'll be -1 as you're only losing 1 dollar. Same goes here. Although 1 is a greater number than 3/12, in negative form it isn't.
