===========================================================
Explanation:
For this answer choice, we have p = 43, q = 133, and r = 89. Note how p+r = 43+89 = 132, which is not larger than the third remaining side q = 133. Therefore, p+r > q is false and a triangle cannot be formed.
A triangle is only possible if and only if adding any two sides leads to a sum larger than the third side (triangle inequality theorem).
Put another way, we must have these three conditions hold true for a triangle to form:
p+q > rp+r > qq+r > pIf any of those three are false, then we cannot make a triangle with side lengths p,q,r
-----------------
Let's go over choice C for an example in which we can form a triangle
p = 5, q = 6, r = 7
We can see that,
p+q = 5+6 = 11 which is greater than r = 7. So p+q > r is true.p+r = 5+7 = 12 which is greater than q = 6. So p+r > q is true.q+r = 6+7 = 13 which is greater than p = 5. So q+r > p is true.All three conditions are true, and therefore we have a triangle that is possible with side lengths p = 5, q = 6, r = 7. I recommend cutting out slips of paper with these lengths to try it out yourself, so you have a real world example to play with. Choices A and D are a similar story to choice C, so we can rule out all three of these choices.

To graph the function g(x) = (x - 5)² - 9, shift the graph of f(x) = x²
5 units right and 9 units down
Step-by-step explanation:
Let us revise the translation
1. If the function f(x) translated horizontally to the right by h units, then
its image is g(x) = f(x - h)
2. If the function f(x) translated horizontally to the left by h units, then
its image is g(x) = f(x + h)
3. If the function f(x) translated vertically up by k units, then its image
is g(x) = f(x) + k
4. If the function f(x) translated vertically down by k units, then its image
is g(x) = f(x) - k
∵ f(x) = x²
∵ g(x) = (x - 5)² - 9
∴ g(x) = f(x - 5)² - 9
∴ h = 5 ⇒ 5 units right
∴ k = -9 ⇒ 9 units down
∴ f(x) translated 5 units to the right
∴ f(x) translated 9 units down
To graph the function g(x) = (x - 5)² - 9, shift the graph of f(x) = x²
5 units right and 9 units down
The graph of g(x) = -1/5(x + 5)² - 2 is plotted making use of the points it passes.
What is a function?A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
The given function is g(x) = -1/5(x + 5)² - 2.
In order to plot its graph, consider following values of x and y as follows,
For x = 0,
g(x) = -1/5(0 + 5)² - 2
= -7
For x = -5,
g(x) = -1/5(-5 + 5)² - 2
= -2
Now as the given function has its degree as 2, it is parabolic.
Thus, its graph can be drawn as follows,
Hence, the graph of the given function is drawn clearly.

On the same day, Parker’s friend, Peggy, was charged $5 for 1 1/2 lb. of gummy candy. Explain in terms of the graph why this must be a mistake.
Answer:
After a quick online search, I've found that the complete question is:
a) Parker paid $4.50 for three pounds of gummy candy. Assuming each pound of gummy candy costs the same amount, complete the table of values representing the cost of gummy candy in pounds.
Then we want to graph the points, and then comes our question:
c) On the same day, Parker’s friend, Peggy, was charged $5 for 1 1/2 lb. of gummy candy. Explain in terms of the graph why this must be a mistake.
So first, we know that this is a proportional relationship (each pound of candy costs the same)
And 0 pounds of candy should cost $0.
Then the relation between y (price) and x (number of lb) is:
y = k*lb
where k is the cost per lb.
Knowing that Parker paid $4.50 for three pounds of gummy candy, the relation is:
$4.50 = k*3lb
($4.50/3lb) = k = $1.50/lb
Then the linear relation is:
y = ($1.50/lb)*x
Now, in this question we can see that Parker's friend was charged $5 for ( 1 and 1/2) lb of candy.
If we replace those values in the equation, we get:
$5 = ($1.50/lb)*(1 + 1/2)lb = $2.25
This equation is false, then, in terms of the graph, the point ( (1 and 1/2)lb, $5) does not belong on the graph that you found in the previous points.
