Answer:
f(3) = -13
Step-by-step explanation:
To answer this question, we plug 3 into the place of x, so the equation now looks like;
f(3) = -5(3) + 2
We simply apply PEMDAS by multiplying -5 and 3, then adding 2 to get;
f(3) = -13
Hope this helps!

Answer:
The solution of this system is
(4). (6.0,5.4)
Step-by-step explanation:
First we have to find the equation of the line represented in the table; for that we have to find it's slope
and it's y-intercept
and then write it in the following form:

The slope
of the line we get from first two points:

thus we have

we find
by putting the point
into the function:


Thus we have

Now we have to find where this line intersects with
; to do this we just substitute
with
:



<em>We have the x-coordinate of the intersection.</em>
We find the y-coordinate by substituting
into
:


Thus the solution to the system is

which is option 4.
