The retail price is $50 because 25% of 40 is 10 and 10+40=50.
Considering the given graph, it is found that the numeric value of the function r(x) at x = -3 is of 2.
<h3>How to find the numeric value of a function given it's graph?</h3>
The numeric value of a function is the value of y for the given value of x, hence, we have to look at the value of x on the horizontal axis, and verify the equivalent value of y on the vertical axis.
In this problem, when the horizontal axis is of x = -3, the vertical axis is of y = 2, hence the numeric value of the function r(x) at x = -3 is of 2.

Answer:
The greatest number of stamps that Nathan can put on each page = 16.
Step-by-step explanation:
Given:
Nathan has:
80 US stamps
64 Canadian stamps
32 Mexican stamps
The stamps need to put on a page such that each page has same number of same country stamps on each page.
To find the greatest number of stamps he can put on each page.
Solution:
In order to find the greatest number of stamps Nathan can put on each page, we will find the G.C.F. of the three numbers.
The numbers are:
<em>We will list down the prime factors of each number.</em>
The G.C.F can be given as = 
= 16
Thus, the greatest number of stamps that Nathan can put on each page = 16.
Answer:
y = 9x-2
Step-by-step explanation:
y=mx+c
slope (m) = 9
y-intercept (c) = -2
Therefore, an equation of the line =
y = 9x-2
Answer:
Option C is correct i.e. 2.
Step-by-step explanation:
Given the function is f(x) = x² +8x -2.
We can compare it with general quadratic expression i.e. ax² +bx +c.
Then a = 1, b = 8, c = -2.
We can find the number of real root by finding discriminant of the equation ax² +bx +c =0 as follows:-
D = b² -4ac
D = 8² -4*1*-2
D = 64 +8
D = 72.
When D is a positive value, then we have two real roots of the equation.
Hence, option C is correct i.e. 2.
