Answer:
p(2) = -9
General Formulas and Concepts:
Pre-Alg
Order of Operations: BPEMDASStep-by-step explanation:
Step 1: Define
p(x) = -2x³ + 4x - 1
p(2) is x = 2
Step 2: Solve
Substitute: p(2) = -2(2)³ + 4(2) - 1Evaluate: p(2) = -2(8) + 4(2) - 1Multiply: p(2) = -16 + 8 - 1Add: p(2) = -8 - 1Subtract: p(2) = -9AGES Zack is 15 years old. This is 3 years younger than his brother Tyler.

a) Find the class interval that contains the median.
b) Work out an estimate for the mean number of hours.
Answer=
a= 2<h<3
b=2.2
a) The class interval that contains the median. is 1 ≤ h ≤ 2.
b) The mean number of hours is, 1.8 h
What is mean and median?The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list. And, The median is the middle value in a list ordered from smallest to largest.
Now,
a) First find the median as,
Median = 30/2
= 15
Now, 6 + 13 = 19 > 19
So, The class interval that contains the median be 1 ≤ h ≤ 2.
b) Let us take the middle of the range as the average;
⇒ (6 × (1 - 0)/2 + 13 × (2 + 1)/2 + 7 ×(2 + 3)/2 + 4 × (3 + 4)/2 ) / 30
⇒ (3 + 19.5 + 17.5 + 14) / 30
⇒ 54/30
⇒ 1.8 hours
So, The value of mean is 1.8.

Select all the statements about the figure that MUST be true. Р Q 6n + 3 S 4n + 11 R PR=15 QS=21 QP=13 n=7 SR=27 QR=54
Answer:
Options (5) and (6)
Step-by-step explanation:
From the picture attached,
In right triangle ΔPSQ and ΔPSR,
PS ≅ PS [By reflexive property]
PQ ≅ PR [Given]
ΔPSQ ≅ ΔPSR [By HL property of congruence]
Therefore, QS ≅ SR [CPCTC]
(6n + 3) = (4n + 11)
6n - 4n = 11 - 3
2n = 8
n = 4
QS = (6n + 3)
= 6×4 + 3
= 27
SR = (4n + 11)
= 4×4 + 11
= 16 + 11
= 27
QR = QS + SR
= 27 + 27
= 54
Therefore, Options (5) and (6) are the correct options.

The equation 4(−2)=1004(−2)=100 is a true equation for a specific value of x. Explain why 2(−2)=502(−2)=50 is also true for the same value of x.
because it halves: 4 ----> 2 so the result also halves ( 1004:2=502 and 100:2=50 )
There is a new kids movie out that everyone is seeing. On the first night the theater sold 200 tickets total. Adult tickets are $8.50, child tickets are $3.50, and they made $1,500 dollars that night. How many adults and how many children saw the movie?
9514 1404 393
Answer:
160 adults40 kidsStep-by-step explanation:
Let 'a' represent the number of adult tickets sold. Then (200-a) is the number of child tickets sold. The total revenue is ...
8.50a +3.50(200 -a) = 1500
5a = 800 . . . . . . . . . . . . . . . . . . . subtract 700 and collect terms
a = 160
(200-a) = 40
160 adults and 40 children paid to see the movie.
Answer:
160 adults and 40 children saw the movie on the first night.
Step-by-step explanation:
Total number of tickets sold = 200
Let the total number of adults be 'x'
So, Total number of children = 200 - x
Cost of adult tickets = $8.50
Cost of child tickets = $3.50
Total sum made on first night = $1,500
Total sum made on first night is equal to total cost of adult tickets + total cost of child tickets
[tex] \longrightarrow [/tex] 8.50x + 3.50(200 - x) = 1500
[tex] \longrightarrow [/tex] 8.5x + 700 - 3.5x = 1500
[tex] \longrightarrow [/tex] 8.5x - 3.5x = 1500 - 700
[tex] \longrightarrow [/tex] 5x = 800
[tex] \longrightarrow [/tex] x = [tex] \sf \dfrac{800}{5} [/tex]
[tex] \longrightarrow [/tex] x = 160
[tex] \therefore [/tex] Total number of adults = 160
Total number of children = 200 - 160 = 40
4(x-3)= -3x + 23 show your work
Answer:
x = 5
Step-by-step explanation:
Expand the brackets
4x - 12 = -3x + 23
Rearrange by collecting the like terms, so that the variables are on one side and the constants are on the other
4x + 3x = 23 + 12
7x = 35
Divide both sides by 7 to make variable on its own
x = 35/7
x = 5
Answer:
x=5
Step-by-step explanation:
4 • (x - 3) - (23 - 3x) = 0
7x - 35 = 7 • (x - 5)
7 • (x - 5) = 0
7 = 0
x-5 = 0
x = 5

The school store earned $625.32 one week, and then $98.36, $145.98, and $304.09 during the next three weeks. How much did the school store earn in the four weeks?
Answer:
The store earned $1173.75 in the 4 weeks
Step-by-step explanation:
To calculate the amount earned by the school in the 4 weeks, we are going to add all what had been earned in the previous weeks;
Mathematically that would be;
$625.32 + $98.36 + $145.98 + $304.09 = $1,173.75

The measures of two vertical angles are 33° and (2x + 3)°. Find the value of x.
Answer:
x = 6
Step-by-step explanation:
If we replace x with 6, we will get 33 degrees. 33 = 33. They are equivalent.
(2*6+3)= 33.
So, x = 6 for both angles to be the same.

Write an equation that represents the line.
Use exact numbers.
Answer:
y = 5/6x + 2.5
Step-by-step explanation:
slope = m = rise/run
equation format - y=mx+b
slope/m= 5/6
y=5/6x+ the y-intercept
the y-intercept is at 2.5
so the full equation would be \/\/\/
y = 5/6x + 2.5
Maritza says that the number y is equal to 5 less than -5 times x. Which of the following equations could be used to find the value of y?
Answer:
y= -5x-5
Step-by-step explanation:
Y is equal to 5 less than -5 times x, which means it is 5 less than -5x.
If y is 5 less than -5x, that means it is equal to -5x-5.
If you were to put that in an equation, it would be y= -5x-5
