the answer is option 2nd (B)
Answer:
B n-12 turns into 12 which makes 7n-5 become -1 +7- 5 = 1
as 12 x7 = 84 and -5 + 84 = 79 our end sequence.

how to approach answering questions for hw and for exam
step 1 hw find a diagram exam rewrite the diagram
step 2 hw work out each multiple question
step 3 see below how workings should be
SIGMA TELLS US The nth term is = k
SIGMA TELLS US The bottom value is value we start with _vs
SIGMA TELLS US The top value is the term we end with - te
A n-2 turns into 9 which makes 7n-5 become -2+7-5 = 0
B n-12 turns into 12 which makes 7n-5 become -1 +7- 5 = 1 (12 x7=84 and -5+84 = 79)
we can prove by using nth common term 7 x 12 -5 = 79
C n -1 turns into 5 which becomes -1+7 = 6
D n- 1 turns into 5 which becomes -1+7-5 = 1
we see the sequence given is 2, 9, 16 ....79 it is ascending sequence +7
we know the nth term is 7n-5 as we work out first step ( 2 - 7= -5)
we see the term we end with is either 9 12 or 5 and we see the end term given value is 72 so B is our answer.

You are stenciling wooden boxes to sell at a fair. Stenciling takes 2 hours for a small box and 3 hours for a large box. Profit for a small box is $10 and $20 for a large box. If
you have no more than 30 hours available to stencil, but want at least 12 boxes to sell, how many of each size box should you sell to maximize your profit? (x = small boxes
and y large boxes)
Solve the problem to fill in the blanks below
Answers
The number of stenciled wooden boxes needed so as to maximize profit is 6 small boxes and 6 large boxes.
Let x represent small boxes and y represent large boxes.
Since you have no more than 30 hours available to stencil, hence:
2x + 3y ≤ 30
Also, at least 12 boxes are required to sell, hence:
x + y ≥ 12
The solution to this problem gives:
x = 6, y = 6
Hence 6 small boxes and 6 large boxes are needed.

Answers
Add 0.5g to both sides:
9 + 3.5g + 0.5g = 11 - 0.5g + 0.5g
9 + 4g = 11
Subtract 9 from both sides:
9 - 9 + 4g = 11 - 9
4g = 2
Divide both sides by 4:
4g/4 = 2/4
g = 1/2

6 identical bags and 3 identical shirts cost 126. 3 such bags cost as much as 2 shirts. what is the cost of one such shirt ?
Answers
Answer:
18
Step-by-step explanation:
Write the information algebraically:
6b + 3s = 126
3b = 2s
(b = bags, s = shirts)
The second line in bold means that we can replace 6b with 4s
3b = 2s (multiply both sides by 2)
∴ 6b = 4s
so, 4s + 3s + 126
Now simplify:
7s = 126
We can now find s by dividing both sides by 7:
s = 126 ÷ 7 = 18
1 shirt costs 18

Put responses in the correct input to answer the question. Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse.
The result of Nick's first step was −x + 9 = −5
1. What was Nick's first step?
The result of Charlie's first step was 9 = x - 5
2. What was Charlie's first step?
Answers
Nick's first step was to subtract 4x from both sides of the equation:
3x - 4x + 9 = 4x - 4x - 5
-x + 9 = - 5
Charlie's first step was to subtract 3x from both sides:
3x - 3x + 9 = 4x - 3x - 5
9 = x - 5
Nick's first step is to bring 4x left and Charlie's is to take 3x right-hand side.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
Given the equation,
3x+9=4x− 5
1. The result of Nick's first step was −x + 9 = −5
So,
3x - 4x + 9 = -5 ⇒ -x + 9 = -5
2. The result of Charlie's first step was 9 = x - 5
3x+9=4x−5
9 = 4x - 3x - 5 ⇒ 9 = x - 5
Hence "Nick's first step is to bring 4x left and Charlie's is to take 3x right-hand side".

The length of a rectangle is 2.5
times its width. The length of
the rectangle is 12 cm. What is
the width of the rectangle?
Answers
Answer:
4.8 cm
Step-by-step explanation:
To find the answer, lets use the information we have. We need to find the width, or w. We know that is 2.5 times smaller than its length, and that the length is 12. So lets make an equation to solve:
12/2.5=w
We did this because we know that the length is 2.5 times bigger than the width, so to find the width we need to go 2.5 times smaller than the length, and the length is 12.
Now solve:
4.8=w
So the width of the rectangle is 4.8 centimeters.
Answer:
width = 4.8 cm
Step-by-step explanation:
let width be w then length = 2.5w
Given length = 12 cm , then
2.5w = 12 ( divide both sides by 2.5 )
w = 4.8
That is width = 4.8 cm

The range of an ambulance service is a circular region bounded by the equation x^2 + y^2 = 400. A straight road within the service area is represented by y = 3x + 20. Find the length of the road that lies within the range of the ambulance service (round your answer to the nearest hundredth). Recall that the distance formula is [tex]d=\sqrt{x(x2-x1)^2+(y2-y1)^2[/tex]
Answers
The straight road crosses the boundaries of the range of the ambulance service at two points
The length of the road that lies within the range of the ambulance service is approximately 37.95
Reason:
The function that represents the ambulance circular service area is x² + y² = 400
The equation that represents the straight road, y = 3·x + 20
Required:
Length of the road that lies within the range of he ambulance
Solution:
The length of the road is given by the distance between the intersection
points of the road and the ambulance service region as follows;
At the intercepts, we have;
The x, and y-values of the line and the circle are equal, therefore, we have;
At the intercept, y = 3·x + 20, which gives;
x² + y² = 400
x² + (3·x + 20)² = 400
x² + 9·x² + 120·x + 400 = 400
10·x² + 120·x + 400 - 400 = 0
10·x² + 120·x = 0
x² + 12·x = 0
x² + 12·x = x·(x + 12) = 0
x = 0, or -12When x = 0, y = 3×0 + 20 = 20
When x = -12, y = 3×(-12) + 20 = -16
The intersection points of the line and the circle are;
A(0, 20), and B(-12, -16)The length of the segment AB, d, is given as follows;
d = [tex]\sqrt{((-12) - 0)^2 + (-16 - 20)^2} = \sqrt{1440} =12 \cdot \sqrt{10}[/tex]The length of the road that lies within the range of the ambulance service, d, given to the nearest hundredth = 12·√(10) ≈ 37.95
