Answer:
y=2x+6 ; x+y=51
Step-by-step explanation:
assuming x is one number and y is the other -
one number (y) is 6 more (+6) than twice another (2x) -
using that knowledge we form an equation -
y=2x+6
the sum (x+y) is 51
using this knowledge we can make the equation -
x+y=51
now you have -
y=2x+6 or 2x-y=-6
x+y=51
using system of equations -
you add the equations -
3x=45
x=15
y=51-x => y=36
hope this helps!!

Answer:
We have the functions,
and
.
After plotting both the functions, we see that,
The graph of F(x) is given below, which has the y-intercept at (0,-1.5) and its horizontal asymptote is x-axis.
Also, the graph of f(x) is a straight line passing through (-4,0) and (0,2).
Further, we can see that the two graphs have intersection points as (-4.873,-0.436) and (2.873,3.436).
