describe how to obtain the graph of g from the graph of f(x) =
[tex] \sqrt{x} [/tex]
Problem 7
Consider the general template
g(x) = a*sqrt(x-h) + k
and compare it to the general parent function
f(x) = sqrt(x)
We have the following variables: a, h and k
They are defined as such:
a = handles the vertical stretch and if any reflections occur. If a > 0, then the curve goes upward; if a < 0, then the curve goes downward. Going from positive to negative, or vice versa, is a reflection over the x axis.h = handles the left and right shift. If h > 0, then you shift right. If h < 0, then you shift left.k = handles the up and down shifting. If k > 0, then you shift up. If k < 0, then you shift down.For this problem, we have
a = 1h = -4k = 3Since g(x) = sqrt(x+4)+3 is the same as g(x) = 1*sqrt(x - (-4)) + 3
With a = 1, we know that the curve moves upward. Compared to the parent graph y = sqrt(x), which also goes upward, no reflection has been done over the x axis.
The h = -4 means we shift 4 units to the left
The k = 3 means we shift 3 units up
Answer: Shift the parent function 4 units to the left and 3 units up=====================================================
Problem 8
We'll use the ideas mentioned in problem 7. They'll also be used for problems 9 and 10 as well.
For problem 8, we have
a = 1h = -4 = shift 4 units to the leftk = -2 = shift 2 units downAnswer: Shift the parent function 4 units to the left and 2 units down.=====================================================
Problem 9
This time we have
a = 1h = 4k = -3Answer: Shift the parent function 4 units to the right and 3 units down=====================================================
Problem 10
So far, all of the 'a' values have been positive 1. This means that there hasn't been any reflection or vertical stretching going on.
This time we have a = -1 instead of a = 1.
So we will reflect over the x axis along with the shiftings similar to the ones that occurred with the previous problems.
Answer: Reflect the parent function over the x axis, shift 4 units to the right, and shift 2 units upEach month the Dover family purchases 16 gallons of

Plot the points A(9, 11) and B(–3, –5). Find midpoint M of AB. Then show that AM = MB and AM + MB =AB
Answer:
The midpoint is (3, 3).
Step-by-step explanation:
We are given the two points A(9, 11) and B(-3, -5).
The midpoint is given by:
[tex]\displaystyle M=\Big(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\Big)[/tex]
So:
[tex]\displaystyle M = \Big( \frac{9+(-3) }{2}, \frac{ 11+(-5) }{2} \Big) = (3,3)[/tex]
The midpoint is (3, 3).
We want to show that AM = MB.
We can use the distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
The distance between A(9, 11) and M(3, 3) will then be:
[tex]AM=\sqrt{(9-3)^2+(11-3)^2}=\sqrt{6^2+8^2}=\sqrt{100}=10[/tex]
And the distance between B(-3, -5) and M(3, 3) will be:
[tex]MB = \sqrt{ (3-(-3))^2 + (3-(-5))^2 } = \sqrt{(6)^2+(8)^2} = \sqrt{ 100 } = 10[/tex]
So, AM = MB = 10.
Since AM = MB = 10, AM + MB = 10 + 10 = 20.
So, we want to prove that AB = 20.
By the distance formula:
[tex]AB=\sqrt{(9-(-3))^2+(11-(-5))^2}=\sqrt{12^2+16^2}}=\sqrt{400}=20\stackrel{\checkmark}{=}20[/tex]
What are the coordinates of the point on the directed line segment from (-8, -2) to
(6,2) that partitions the segment into a ratio of 1 to 3?
Answer:
The coordinates of the point are (-4.5,-1).
Step-by-step explanation:
We want to find point T(x,y).
I am going to say that out points are A(-8,-2) and B(6,2)
Since it partitions the segment in a 1:3 ratio, we have that:.
[tex]T - A = \frac{1}{1+3}(B-A)[/tex]
[tex]T - A = \frac{1}{4}(B-A)[/tex]
We apply this to both the x-coordinate and y-coordinate of T.
x-coordinate:
x-coordinate of A: -8
x-coordinate of B: 6
x-coordinate of T: x.
So
[tex]T - A = \frac{1}{4}(B-A)[/tex]
[tex]x - (-8) = \frac{1}{4}(6-(-8))[/tex]
[tex]x + 8 = \frac{14}{4}[/tex]
[tex]x = \frac{14}{4} - 8[/tex]
[tex]x = \frac{14}{4} - \frac{32}{4}[/tex]
[tex]x = -\frac{18}{4}[/tex]
[tex]x = -4.5[/tex]
y-coordinate:
y-coordinate of A: -2
y-coordinate of B: 2
y-coordinate of T: y.
[tex]T - A = \frac{1}{4}(B-A)[/tex]
[tex]y - (-2) = \frac{1}{4}(2-(-2))[/tex]
[tex]y + 2 = 1[/tex]
[tex]y = -1[/tex]
The coordinates of the point are (-4.5,-1).
Simply the expression by combining like terms 6x+9+2x+4

at a party 136 handshakes took place. each person shook hands exactly once with each of the others present. how many people were at the party?
9514 1404 393
Answer:
17
Step-by-step explanation:
The number of handshakes among n people is n(n -1)/2. Then ...
n(n -1)/2 = 136
n(n -1) = 272 = 17×16*
n = 17
There were 17 people at the party.
_____
* This factoring can be facilitated by recognition that √272 ≈ 16.5, the number midway between the consecutive factors.

Step-by-step explanation:
Hannah and Anthony are siblings who have ages that are consecutive odd integers. The sum of their
ages is 92. Which equations could be used to find Hannah's age, h, if she is the older sibling?
Answer:
2h-2=92 and h-2=92-h.
Step-by-step explanation:
Hannah, h, is the older sibling and their ages are consecutive odd integers. This means that Anthony's age will be 2 less than Hannah's, or h-2.
The sum of these would be h+(h-2), giving us the equation h+(h-2)=92.
Combining like terms we would have the first correct choice, 2h-2=92.
Our first equation can be transformed, however, to have (h-2) by itself. To do this, we would subtract h from both sides, giving us h-2=92-h.
The equation that will represent the sum of the age of Hannah and Anthony will be 2x+2=92.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the age of Hannah be x. and Since the age of Hannah and Anthony are two consecutive odd integers, therefore, the age of Anthony will be (x+2).
As it is given that the sum of the ages of the two other person is 92, therefore, the equation that will represent the sum of the age of the two persons can be written as,
[tex]x+(x+2)=92\\\\x+x+2=92\\\\2x+2=92[/tex]
Thus, the equation that will represent the sum of the age of Hannah and Anthony will be 2x+2=92.
