Solve the following system of equations by substitution. Show all steps.
Alinara [238K]

Answer:

Given system of equations:

\begin{cases}f(x)=-x^2+2x+3\\g(x)=-2x+3\end{cases}

To solve by substitution, equate the equations and solve for x:

\begin{aligned}f(x) & = g(x)\\\implies -x^2+2x+3 & = -2x+3\\-x^2+4x & = 0\\x^2-4x & = 0\\x(x-4) & = 0\\\implies x & = 0\\\implies x-4 & = 0 \implies x=4\end{aligned}

Therefore, the x-values of the solution are x = 0 and x = 4.

To find the y-values of the solution, substitute the found values of x into the functions:

f(0)=-(0)^2+2(0)+3=3

g(0)=-2(0)+3=3

f(4)=-(4)^2+2(4)+3=-5

g(4)=-2(4)+3=-5

Therefore, the solutions to the given system of equations are:

(0, 3) and (4, -5)

The image is not very much enlarged, and is slanted, so answers might be just approximate.
(a) median is 39 or 40, your choice.
(b) 3rd quartile of y looks 47 or 48
(c) variable y has more disperson, since both the extremes and the quartiles are spread out longer that those of variable x.
(d) since both halfs of the blue box (of x) and both lines outside of the box are basically equal, variable x's distribution is very much symmetric.
Sorry, cannot read question part (e) completely.
