What is the equation of a trend line that passes through the points (7,450) and (14,401).
Answer:
y = -7x + 499
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Slope Formula: [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Step 1: Find slope m
m = (401 - 450)/(14 - 7)
m = -49/7
m = -7
y = -7x + b
Step 2: Find b
450 = -7(7) + b
450 = -49 + b
499 = b
Step 3: Rewrite equation
y = -7x + 499
Write 120 as a product of prime factors
The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120.
And the prime factorization of 120 is 2 x 2 x 2 x 3 x 5
In this exercise we must use the knowledge about prime factors to find the products of the number 12, in this way we find that:
[tex]2 * 2 * 2 *3 * 5[/tex]
First, we have to remember what prime factors are, like this:
Prime factors happen determinant of a number that happen, themselves, prime numbers. There exist many plan to find the prime determinant of any, but individual of the most prevalent search out use a prime determinant large plant enclosed in bark and shedding leaves.
So for the number 12, we find that this corresponds to:
[tex]1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120\\ 2 * 2 * 2 *3 * 5[/tex]

Answer: 33 degrees
Step-by-step explanation: Angle x=angle m
Answer:
the triangle on the left is named XYZ
the triangle on the right is named MNL
therefore ∠X ≅ ∠M, ∠Y ≅∠N, and ∠Z ≅ ∠L
since ∠X = 33º, then ∠M = 33º

Elsa, Alan, and Deon have a total of $82 in their wallets. Alan has 3 times what Deon has. Deon has $7 less than Elsa. How much do they have in their wallets?
Answer:
Alan=$45
Deon=$15
Elsa=$22
Step-by-step explanation:
Let
Elsa=x
Deon=x-7
Alan=3(x-7)
Total=$82
x+(x-7)+3(x-7)=82
x+x-7+3x-21=82
5x-28=82
5x=82+28
5x=110
x=110/5
=22
Elsa=x=$22
Deon=x-7
=22-7
=$15
Alan=3(x-7)
=3(22-7)
=3(15)
=$45
Here are the first 5 terms of a sequence 3,8,17,30,47 find an expression, in terms of n for the nth term of this sequence
Answer:
The first differences are 5, 9, 13, 17, and so the second differences are all 4.
Halving 4 gives 2, so the first term of the sequence is 2n^2.
Subtracting 2n^2 from the sequences gives 1,0,-1-2,-3 which has the nth term -n+2.
Therefore, the formula for this sequence is 2n^2 -n +2.

2n^2 - n +2

Answer:
a) (-2,-1) b) (-3,0) & (-1,0)
Step-by-step explanation:
For the first part, the turning point is simply where the graph curves. We can see that that happens on (-2, -1).
For the second part, the roots of the equation are simply when the graph crosses the x-axis. This happens twice, at (-3,0) and (-1,0)
Answer:
see explanation
Step-by-step explanation:
(a)
The turning point is where the curve reaches its lowest point before increasing again.
The coordinates of the turning point are (- 2, - 1 )
(b)
The roots are the points on the x- axis where the graph crosses.
The coordinates of the roots are (- 3, 0 ) and (- 1, 0 )

Answer:
The balcony seat costs $9, the orchestra seat costs $9 + $6 = $15.
Step-by-step explanation:
Let x is the cost/price of one balcony seat, in dollars.
Then the cost of one orchestra seat is (x+6) dollars, according to the condtion.
The total cost of tickets is
250x + 400*(x+6) = 8250.
Simplify it step by step.
250x + 400x + 2400 = 8250,
650x = 8250 - 2400 = 5850 ====> x = 5850/650 = 9.
Answer. The balcony seat costs $9, the orchestra seat costs $9 + $6 = $15.
Check. 9*250 + 15*400 = 8250. Correct.
Answer:
C
Step-by-step explanation:
Let x = price of one balcony seat and y = price of one orchestra seat
Price of orchestra seat = Price of balcony seat + 6
Or y = x + 6
[tex]400 \times price \: of \: orchestra \: seat \: + \: 250 \times price \: of \: balcony \: seat \: = 8250[/tex]
Or 400y + 250x = 8250
Now that we have to two equations with two variables, we can use either substitution, elimination or graphing to find the prices of the seats.
I attached a picture of the graph. Remember since we set y as the price of the orchestra seat, the y coordinate in the point of intersection will be the price for one orchestra seat. This will be the same for the price of a balcony seat and the x coordinate.
Therefore, the price of one balcony seat is $9 and the price of one orchestra seat is $15.

Suppose you work for a company that manufactures cylindrical cans. Which will cost more to manufacture, a can with a radius of 4 inches and a height of 5 inches, or a can with a radius of 5 inches and a height of 4 inches? Assume that the cost of material for the tops and bottoms is per $1.40 square inch and the cost of material for curved surfaces is $0.90 per square inch.
Answer:
the can with the 5-inch radius will cost more
Step-by-step explanation:
The cost will be given by the formula ...
cost = 1.40 × (top & bottom area) + 0.90 × (lateral area)
In terms of radius and height the areas are ...
top & bottom area = 2πr²
lateral area = 2πrh
So, the total cost of a can with radius r and height h is ...
c(r, h) = 1.40·2πr² +0.90·2πrh
Filling in the given values and doing the arithmetic, we find the costs to be ...
c(4, 5) = $253.84
c(5, 4) = $333.01
The cost of the can with the 5-inch radius is the greatest.
Answer:
The cylinder with radius of 5 inches and height of 4 inches costs more to manufacture.
Step-by-step explanation:
First Can:
Top and Bottom Surface Area = 2(pi(4)^2) = 2(16pi) = 32 pi = 100.53 square inches
Cost for top and bottom surface area = 1.40 * 100.53 = $140.74
Curved Surface Area = 2pi*r*h = 2*pi*4*5 = 40 pi = 125.66 square inches
Cost for Curved Surface Area = 125.66 * 0.90 = $113.10
Total Cost = $140.74 + $113.10 = $253.84
Second Can
Top and Bottom Surface Area = 2(pi(5)^2) = 2(25pi) = 50 pi = 157.08 square inches
Cost for top and bottom surface area = 1.40 * 157.08 = $219.91
Curved Surface Area = 2pi*r*h = 2*pi*5*4 = 40 pi = 125.66 square inches
Cost for Curved Surface Area = 125.66 * 0.90 = $113.10
Total Cost = $219.91 + $113.10 = $333.01
So, the cylinder with radius of 5 inches and height of 4 inches costs more to manufacture.

Answer:
x = 5
Step-by-step explanation:
Step 1: Write equation
-3/4 + 2/5x = 7/20x - 1/2
Step 2: Subtract 7/20x on both sides
-3/4 + 1/20x = -1/2
Step 3: Add 3/4 to both sides
1/20x = 1/4
Step 4: Divide 1/20 on both sides
x = 5
Answer: Answer: The answer is A,C,E
A: 2/5x = 7/20 x+ 1/4
C: -3/4 = -1/20 x -1/2
E: -3/4 + 1/20 x= -1/2
945 divided by 35 with remainders
Answer:
27.
Step-by-step explanation:
945 / 35 = 27. There are no remainders... Although you could potentially say that 0 is the remainder.
When 945 is divided by 35, the remainder is 0 and quotient is 27.
The divisor is 35 and the dividend is 945.
We have to find the quotient and remainder when 945 is divided by 35.
945/35
=27.
Hence, the quotient is 27 and remainder is 0.

Answer:
Option (E)
Step-by-step explanation:
Expression given in the attachment,
[tex]x-\frac{15}{x}=2[/tex]
By multiplying with x on both the sides of the given equation,
x² - 15 = 2x
x² - 2x - 15 = 0
x² - 5x + 3x - 15 = 0
x(x - 5) + 3(x - 5) = 0
(x + 3)(x - 5) = 0
(x + 3) = 0
x = -3
And (x - 5) = 0
x = 5
Therefore, x = -3, 5 are the solutions of the given equation.

Answer:
y = 2/3x - 2
Step-by-step explanation:
I'm pretty sure this is asking about the slope intercept form, since you didn't give us the actual answers. If not, comment below. Slope intercept form follows the y = mx + b form, where m is the slope and b is the y-intercept. By plugging your givens in, you get y = 2/3x - 2
