Answer:
Multiply the bottom one by -4
Step-by-step explanation:
to cancel in a system of equations, there must be a negative and a positive of both variables. - times - equals +, so multiply -x by -4 to get 4x, thus cancelling -4x with 4x.
Answer:
Observe the attached image
Step-by-step explanation:
We know that
is an exponential function, therefore its graph must have the form that corresponds to this type of functions.
The first thing to do is find the cut points of the function.
Cut point with the y axis:

The function cuts the y-axis on 
Cutting point with the x axis:

To clear x we must apply log on both sides of the equality, but the log(0) is not defined. Then, the function does not cut to the x axis.
The graph that represents the function f(x) is the one that cuts in
and does not cut the x-axis
It would be the second option n^3 (4n+1)
Answer:
C. 3
Step-by-step explanation:
3 x 5 = 15, 15 + 2 = 17 :)
It would be C because it is right
