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:

$30.78 from the raise
Step-by-step explanation:
The answer is -13z because there is no reasons to square it, it cannot be positive, and there has to be a z in the answer.
Answer:
100 degrees C.
Step-by-step explanation:
100 degrees C
The 'size' of the unit is the same.
0 degrees K to 100 degrees K is equivalent to:
-273 degrees C to - 173 degrees C.
