If you shift the quadratic parent function f(x))=x^2 to the right 10 units what is the equation to the new function
A.) g(x)=x^2-10
B.) g(x)=x^2+10
C.)g(x)=(x+10)^2
D.)g(x)=(x-10)^2
Answer:
D
Step-by-step explanation:
First of all, you are moving right. That means that something gets added or subtracted from the x
To move right whatever number units you move right, will be subtracted from the x.
A and B are are both wrong. It is really the y that the +/- ten changes.
C is wrong because you are moving left, not right.
D is the answer. It is not intuitive, but it is how how move right.

Pam and Amanda and Mike work at different clothing stores. Amanda made twice what Pam earned and Julie
made $90 more than Amanda. If their total earnings for a week are $995, how much did each person make?
Answer:
Pam: $181
Amanda: $362
Julie: $452
Step-by-step explanation:
(What does Mike have to do with this problem?)
Let a = Amanda's pay
Let p = Pam's pay
Let j = Julie's pay
"Amanda made twice what Pam earned"
a = 2p
"Julie made $90 more than Amanda"
j = a + 90
j = 2p + 90
Pam earned p
Total salary
a + p + j = 2p + p + 2p + 90
Total salary
$995
2p + p + 2p + 90 = 995
5p = 905
p = 181
a = 2p = 2(181) = 362
j = 2p + 90 = 362 + 90 = 452
Answer:
Pam: $181
Amanda: $362
Julie: $452

Answer:

Step-by-step explanation:
Look for the exponets that are in decending order such as 5 2 1
Decrease 1500goats by 20%
A 1200
B 300
C 1800
D 900
Answer:
A
Step-by-step explanation:
1500 goats represent 100%
but 100% = 5*20%
1500 = 5*300 so 20% =300
a decrease by 20% is 1500-300 = 1200
Instructions: Point T is the centroid. Find TE if XE= 21.
Answer:
TE = 7
Step-by-step explanation:
The centroid divides a median in this ratios 1/3 and 2/3. In particular

Write the set of non-negative integers in the inequality 2x < 4.
Answer:
The set [tex]S[/tex] of non-negative integers in the inequality [tex]2x < 4[/tex] is
[tex]S = \{0, 1\}[/tex]
Step-by-step explanation:
The non-negative integers are given as [tex]\mathbb{Z}_{\ge 0} = \{ 0, 1, 2, \ldots \}[/tex]
For the inequality [tex]2x < 4[/tex], we have
[tex]2x < 4 \implies x < \dfrac{4}{2} \implies x < 2[/tex]
Therefore,
[tex]x\in \mathbb{R}:x\in(\infty, 2)[/tex]
Note: 2 is not included
The integers are
[tex]\ldots -2, -1, 0, 1[/tex]
And the non-negative integers are

In ⊙H, Arc I K ≅ Arc J K, mArc I K = (11x + 2)°, and mArc J K = (12x – 7)° What is the measure of Arc I J K?
Answer:
202°
Step-by-step explanation:
Arc I K ≅ Arc J K, Given that mArc I K = (11x + 2)°, and mArc J K = (12x – 7)°. SInce Arc I K ≅ Arc J K, then;
(11x + 2)° = (12x – 7)°
Collect the like terms
11x - 12x = -7 - 2
-x = -9
x = 9
Arc IJK = 11x+2 + 12x - 7
Arc IJK = 23x-5
Arc IJK = 23(9)-5
Arc IJK = 207-5
Arc IJK = 202°
Hence the measure of Arc IJK is 202°

Answer:
Step-by-step explanation:
#1. For lines l and m to be parallel, angles 3 and 6 would have to add up to equal 180. This is the Same Side Interior Angle Theorem.
For #2, angles 3 and 7 are corresponding, meaning they are in the same place in both angle groups. Because of this, they are congruent. That means that they equal one another.
If angle 3 is 4x + 12 and x = 15, then angle 3 = 72.
If angle 7 is 80 - x and x = 15, then angle 7 = 65. So if this is the case, the lines l and m are not parallel. In order for them to be parallel, angle 3 has to equal angle 7:
4x + 12 = 80 - x and we solve for the value of x that will make the lines parallel:
5x = 68 so
x = 13.6
This graph shows how the length of time a kayak is rented is related to the
rental cost. What is the rate of change shown in the graph?
Kayak Rental
A. 8 hours/dollar
B. 4 hours/dollar
C. $4/hour
D. $8/hour
Answer:
option D.
Step-by-step explanation:
[tex]rate \: of \: change \: = \frac{change \: in \: y}{change \: in \: x} [/tex]
let's take any point on the graph. let's say (2, 16)
and one point we know is (0, 0)
[tex]rate \: of \: change = \frac{16 - 0}{2 - 0} [/tex]
= 16($) / 2 (hrs)
= 8 $/ hrs
that is option D.
Answer:
$8/hour
Step-by-step explanation:
Hi there!
In this scenario, the independent variable is time and the dependent variable is the cost. The cost of renting the kayak depends on how much time passes. Knowing this, the answer should be formatted like _ dollars/hour, not _hours/dollar. We can rule the first two options out.
Now, looking at the graph, when 1 hour passes, the cost is $8. This occurs at point (1,8). And this is constant throughout, for example, when 2 hours pass, the cost is $16 (2,16).
Therefore, the rate of change shown in the graph is $8/hour.

Triangle MNP is dilated according to the rule DO,1.5 (x,y)Right arrow(1.5x, 1.5y) to create the image triangle M'N'P, which is not shown.
On a coordinate plane, triangle M N P has points (negative 4, 6), (2, 6), and (negative 1, 1).
What are the coordinates of the endpoints of segment M'N'?
M'(-6, 9) and N'(4, 9)
M'(-6, 9) and N'(3, 9)
M'(-2, 3) and N'(7, 9)
M'(-2, 3) and N'(1, 3)
Given:
The vertex of a triangle MNP are M(-4, 6), N(2, 6), and P(-1, 1).
The rule of dilation is:
[tex](x,y)\to (1.5x,1.5y)[/tex]
The image of triangle MNP after dilation is M'N'P'.
To find:
The coordinates of the endpoints of segment M'N'.
Solution:
The end points of MN are M(-4, 6) and N(2, 6).
The rule of dilation is:
[tex](x,y)\to (1.5x,1.5y)[/tex]
Using this rule, we get
[tex]M(-4,6)\to M'(1.5(-4),1.5(6))[/tex]
[tex]M(-4,6)\to M'(-6,9)[/tex]
And,
[tex]N(2,6)\to N'(1.5(2),1.5(6))[/tex]
[tex]N(2,6)\to N'(3,9)[/tex]
The endpoints of M'N' are M'(-6, 9) and N'(3, 9).

Answer:
3) x = 55, y = 123, z = 123
4) x = 276°
Step-by-step explanation:
3)Angles P and Q are alternate interior angles, so are congruent.
P = Q
3x -42° = 2x +13°
x = 55° . . . . . . . . . . . add 42°-2x
Then Q = 2x +13 = 2(55°) +13° = 123°.
Angles Y, P, Q, and Z are all congruent, so all have the same measure.
Y = Z = 123°
__
4)If you draw a horizontal line parallel to AB and CD through point O, then small angle POQ is divided into parts that are congruent with angles APO and CQO. That is, small angle POQ = 48° +36° = 84°.
Large angle POQ is then 360° -84° = 276°

Una empresa textil dedicada a la confección y venta de pantis Glamour realiza la siguiente promoción de sus productos: para pedidos de hasta una decena, el par de pantis Glamour de cualquier tamaño lo vende a S/. 5. Pero si se hacen pedidos mayores a una decena de pares, cada par de media tiene un valor de S/. 3.
Respuesta:
S / 25
S / 45
S / 75
Explicación paso a paso:
Dado :
Para pedidos de hasta una docena; par de pantimedias Glamour Costo S / 5
Para pedidos de más de una docena; par de pantimedias Glamour Costo S / 3
Función de costo:
Para x ≤ 12
Costo, C = 5x
Para x> 12
Costo, C = 3x
Costo de 5 pedidos:
x = 5
Costo, C = 5 (5) = S / 25
Costo de 15 pedidos:
x = 15
Costo, C = 3 (15) = S / 45
Costo de 25 pedidos:
x = 25
Costo, C = 3 (25) = S / 75
