Answer:a
Step-by-step explanation:
Answer:
f (x) = x2 shows us that function " f " takes " x " and squares it. Example: with f (x) = x2: becomes an output of 16. In fact we can write f (4) = 16. The "x" is Just a Place-Holder! Don't get too concerned about "x", it is just there to show us where the input goes and what happens to it.
Answer:

Step-by-step explanation:
We can use the point-slope formula given by:

The given line passes through the
point (-3,2) and having slope
.
We substitute the given point and slope to get:


we clear the fraction to get;




Or in standard form:

X+2y=23
X=-2y +23
Plug this in for x in the second equation
5(-2y + 23) + 10y = 55
-10y + 115 + 10y = 55
The -10y + 10y cancel out, so there is no solution
Hope this helps!
