Why do some quadratic graphs move left or right and others do not? Is there a correlation between this and them moving up and down? How would you demonstrate your reasoning is correct?
Answers
Answer:
(x + 3)^2 is left 3 because it becames 0 at -3
(x - 3)^2 is right 3 because it becames 0 at 3
x^2 +3 is up 3 because your just adding 3 units up
x^2 - 3 is down 3 because your just subtracting 3 units down

The mean, mode, range, and median of the 3 weights will be 8, does not exist, 6, and 8, respectively.
What are statistics?Statistics is the study of collection, analysis, interpretation, and presentation of data or discipline to collect, and summarise the data.
Delaney’s dog has three puppies. One weighs 5 pounds, one weighs 8 pounds, and one weighs 11 pounds.
The mean of the 3 weights is calculated as,
Mean = (5 + 8 + 11) / 3
Mean = 8
The mode of the 3 weights is calculated as,
Mode = Does not exist
The range of the 3 weights is calculated as,
Range = 11 - 5
Range = 6
The median of the 3 weights is calculated as,
Median = (3 + 1) / 2
Median = 2nd
Median = 8

The example here in the problem is 5 minutes for 500 yards as 5:500

At Pruitt’s farm, the ratio of oranges to apples is 4 to 8. A total of 96 apples and oranges are grown on his farm. Find the number of oranges grown.
A. 64
B. 32
C.12
D. 16
Answers
Answer:
32 (B)
Step-by-step explanation:
Because there is a total of 96 apples and oranges, you would divide 96 by 12 because 4 + 8 = 12. 96/12 is 8, so we know that each part (1 part of the ratio) would be 8. Since we are finding the number of oranges, you would multiply 4 x 8 which is 32. (B)
At the beginning of the school year, 70 students signed up for music lessons. Students could choose drums, guitar, piano, or violin. The results are shown in the table. Which is a true statement about this situation?
Instrument Boys Girls

Guitar 6 8
Piano 9 15
Violin 4 11
A.
About 28% of students signed up for violin lessons.
B.
About 17% of students signed up for drum lessons.
C.
A greater percent of boys are taking piano lessons than girls.
D.
The same percent of boys and girls are taking guitar lessons.
Answers
Answer:
D.
Step-by-step explanation:
1. Answer A:
15 students signed up for violin lessons (4 boys + 11 girls)
15 / 70 = approx. 21% of the class.
Answer A says 28%, so this is incorrect.
2. Answer B:
17 students signed up for drum lessons (11 boys + 6 girls)
17/70 = approx. 24%
B says 17% signed up for drums, so this is incorrect.
3. Answer C.
Wrong because more girls signed up for piano lessons (15 girls, whereas only 9 boys signed up for piano)
4. D. The same percent of boys and girls are taking guitar lessons.
Get the total number of boys and girls in the class (just add the results for each separately for all instruments)
Boys: 11 + 6 + 9 + 4 = 30
Girls: 6+8+15+11 = 40
6 out of 30 boys signed up for guitar
6/30= 20%
8 out of 40 girls signed up for guitar
8/40 = 20%

y - 6 = x/3 + 17/3 - 6
Step-by-step explanation:
x₁,y₁
A(-5,4)
x₂,y₂
B(1,6)
m = (y₂ - y₁) / (x₂ - x₁)
m = (6 - 4) / (1 - (-5))
m = 2 / (1 + 5)
m = 2/6
m = 1/3
y = mx + b B(1,6)
6 = (1) * 1/3 + b
6 = 1/3 + b
b = 6 - 1/3
b = (18 - 1) / 3
b = 17 / 3
y = x/3 + 17/3
y - 6 = x/3 + 17/3 - 6

Answer:

Step-by-step explanation:
\(105+3x=180 \\ \\ 3x=75 \\ \\ x=25\)
Answer:
The answer is 25 degrees
Step-by-step explanation:
If you subtract 180 - 105 then you get 75.
Then you divide it by 3.
One circle is 360 degrees thus half of it is 180.
If you know one angle is 105 degrees then subtract it from 180.
If the number is 3x then you have to divide it by 3 to get x alone.

Alexis went back-to-school shopping. She purchased one pack of markers for $2.50, a lunchbox for $5.25, and two shirts for $7.99. She used a 20%-off coupon. How much did Alexis owe? Show your work.
Answers
Answer: $12.60
Step-by-step explanation:
after adding to the total with the markers, lunchbox and shirts you get $15.75 then multiply the normal price $15.75 by 20 then divide it by one hundred and you will get $3.15 as your saved amount and you will then do 15.75-3.15= 12.6 make sure to put a 0 after the 6 making it 60.
(2.50+5.25+7.99= $15.75)
(15.75-3.15= 12.60)

Change the inequalities below to get 'y' by itself.(Please help me. I don't get how to do inequalities.)
x - y > 4
Answers
Answer:
y < x - 4
Step-by-step explanation:
First, move the x over to the other side by subtracting x from both sides. This will get you -y > -x + 4.
Divide both sides by -1 to get rid of the -1 in front of y. Since this is an inequality, dividing or multiplying by a negative number means that you have to flip the sign. We are dividing by a negative number, so flip > to <. The signs on both sides change to get y < x - 4.
