How many solutions does the system of equations below have? y=x-2 -x+y=-5

Mathematics
1 answer:
Helen [10]4 years ago
5 0
The system of equations has no solutions.

We can show this by substituting the first equation into the second equation:

y = x - 2

-x + y = -5
-x + (x - 2) = -5
-x + x - 2 = -5
-2 = -5

Clearly this is not true so there are no solutions.

I hope this helps!

What is f(x)=2(3)^x?
HACTEHA [7]

Answer:

This is an exponential function

Step-by-step explanation:

f(x)=2(3)^x is one example of the exponential function.  Since f(0) = 2(1) = 2, the y-intercept is (0, 2).  The x-axis is the horizontal asymptote.  The graph begins in Quadrant II, passes through (0, 2) and continues to increase, faster and faster, in Quadrant I.  Next time, please be more specific about what you'd like to know.
