If f(x) = x
What is g(x) if the graph moves 9 units up and 2 units to the right
Answers
Shift 2 units left: y = [tex](x+2)^{2}[/tex]
shift up 9 units: y = [tex](x+2)^{2}[/tex] + 9
reflect in the x-axis: y = - [tex](x+2)^{2}[/tex] - 9
y =[tex]x^{2}[/tex]
Shift 2 units left: y = [tex](x+2)^{2}[/tex]
Then, shift up 9 units: y = [tex](x+2)^{2}[/tex] + 9
Then, reflect in the x-axis: y = - [tex](x+2)^{2}[/tex] - 9
Each reference coordinate line is referred to as an axis of the system, or simply an axis (plural axes), and its origin is at the ordered pair intersection (0, 0). The positions of the perpendicular projections of the point onto the two axes, represented as signed distances from the origin, can likewise be used to establish the coordinates.
The same idea may be used to determine the location of any point in three dimensions using three Cartesian coordinates.

Tia climbed to the top of an observation tower overlooking a bird sanctuary and used the telescope at the top to observe two nests. The first nest was 400 meters away from the observation tower. Tia turned the telescope 135 degrees to observe the second nest, which was 300 meters away. How far apart are the two nests?
Answers
Answer:
648 m
Step-by-step explanation:
Given observations of two nests, one at 400 m, and the other at 300 m in a direction 135° from the first, you want to know the distance between the nests.
Law of CosinesThe law of cosines can be used to find the third side of a triangle, given two sides and the angle between them. It tells us ...
c² = a² +b² -2ab·cos(C)
In this scenario, we have a=400, b=300, and C=135°. The distance c is then ...
c² = 400² +300² -2·400·300·cos(135°) ≈ 419,705.63
c ≈ √419,705.63 ≈ 647.8
The two nests are about 648 meters apart.
The table shows the results of a survey of male and female students about whether their school should adopt a dress code. What is the probability that a randomly selected male student says that the school should adopt a dress code? Give your answer as a decimal rounded to the nearest thousandths
Answers
Using it's concept, there is a 0.462 probability that a randomly selected male student says that the school should adopt a dress code.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
From the table, we have that:
There are 30 + 35 = 65 male students.30 say that the school should adopt a dress code.Hence the probability is given by:
p = 30/65 = 0.462.
0.462 probability that a randomly selected male student says that the school should adopt a dress code.

was the maximum number of people that could be helped with one plane of supplies?
Answers
Using a system of equations, it is found that the maximum number of people that could be helped with one plane of supplies is: 40,000.
What is a system of equations?A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem.
For this problem, the variables are given as follows, considering the situation described:
Variable x: number of food kits sent.Variable y: number of medicine kits sent.Each food kit helped 8 people and each medicine kit helped 6 people, hence the total number of people helped is given by:
T = 8x + 6y.
This is because we consider that people were helped by only one of them, never both.
Each plane could carry no more than 80,000 pounds. Each food kit weighed 20 pounds and each medicine kit weighed 10 pounds, hence:
20x + 10y = 80000
2x + y = 8000
y = 8000 - 2x.
The maximum volume is of 6000 cubic feet, hence:
x + y = 6000.
y = 6000 - x.
Equaling both equations:
8000 - 2x = 6000 - x
x = 2000.
y = 6000 - x = 4000.
Then the maximum number of people helped is:
T = 8x + 6y = 8 x 2000 + 6 x 4000 = 40,000.

Point Q is the midpoint of segment PR. QR = 18 and PR = 5x+6.
Answers
we get the value of x as 2.4 units when QR is 18 units.
We are given a segment PR.
We are also given that Q is the mid point of the segment.
So, we get that
PQ = QR
Now, we have that
QR = 18 units
PR = 5 x + 6
We have to sind the value of x.
Substituting the values of PR and QR in the equation, we get that:
5 x + 6 = 18
5 x = 18 - 6
5 x = 12
x = 12 / 5
x = 2.4 units
Therefore, we get the value of x as 2.4 units when QR is 18 units.

Using a system of equations, it is found that you should mix 7 pounds of dried fruit and 3 pounds of nut.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given as follows:
Variable x: Number of pounds of dried fruit mix.Variable y: Number of pounds of nut mix.The mixture has a total of 10 pounds, hence:
x + y = 10 -> y = 10 - x -> x = 10 - y.
Considering the cost per pound of each, and the total cost of 10 x 5.34 = $53.4, we have that:
4.5x + 7.3y = 53.4.
Replacing x = 10 - y, we have that:
4.5(10 - y) + 7.3y = 53.4.
2.8y = 8.4.
y = 8.4/2.8
y = 3.
x = 10 - 3 = 7.
You should mix 7 pounds of dried fruit and 3 pounds of nut.

Step-by-step explanation:
this question is horribly phrased.
as far as I can tell after reading this multiple times, this is again looking for the GCF : the greatest common factor.
so, again, prime factor analysis :
168 :
168 ÷ 2 = 84
84 ÷ 2 = 42
42 ÷ 2 = 21
21 ÷ 2 no
21 ÷ 3 = 7
7 ÷ 3 no
7 ÷ 5 no
7 ÷ 7 = 1 finished
168 = 2³×3×7
120 :
120 ÷ 2 = 60
60 ÷ 2 = 30
30 ÷ 2 = 15
15 ÷ 2 no
15 ÷ 3 = 5
5 ÷ 3 no
5 ÷ 5 = 1 finished
120 = 2³×3×5
the GCF is the part of the prime factors both numbers share :
2³×3 = 8×3 = 24
so, they can make 24 fruit cups with identical content and using all the fruits.
these pieces of information were missing in the text.
based on the text without the answer options I was already going for the maximum that each fruit cup has one piece of fruit, and that gives us 168 + 120 = 288 fruit cups max.

park-and-ride in Daytona Beach to the KSC headquarters building, and then takes the KSC shuttle from the headquarters building to
the VAB. The drive from the park-and-ride to the headquarters building is of her total trip, and the shuttle ride is of her total trip.
How many miles does she travel from her house to the VAB on days her colleague drives?
Answers
Using proportions, it is found that she travels 60 miles from her house to the VAB on days her colleague drives.
What is the missing information?The drive from the park-and-ride to the headquarters is 5/6 of her trip.The shuttle ride is 1/20 of her trip.What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
The first step is finding the fraction corresponding to the 7 miles, hence considering that the total is of 100% = 1 and the fractions given above, we have that:
1 - 5/6 - 1/20 = 1 - 0.8333 - 0.05 = 0.1167.
The 7 miles represent 0.1167 of the trip, hence:
0.1167x = 7
x = 7/0.1167
x = 60.
