Answer:
The equation is y= 0,65 x
If x is the price of the ticket without the coupon, and the theater offers a discount if you have a coupon, then having a coupon means that the price a person ultimately pays (y) is the original price (x) minus a 35% of this price: y= x -0.35 x . By association: y= (1-0.35) x and then y= 0.65 x.
The line should be in the first quadrant because the first quadrant allows you to represent a situation in which the dependent variable (y) and the independent variable (x) are both positive. This is the case in this exercise, because both prices, the one without discount (x) and the one with discount (y) are necessary positive (you can not pay a negative price!).
Step-by-step explanation:
The price without discount (or without the coupon) is x.
The price with discount (or with coupon) is y.
y and x are both related: y is a percentage of x, specifically, y is 35% smaller than x. This means that y =0.65 x.
Answer:
0.85x

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
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.

Henry and Gavin are marking exam papers. Each set takes Henry 36 minutes and Gavin 1 hour. Express the times Henry and Gavin take as a ratio.
Give your answer in its simplest form.
Answer: 3:5
Step-by-step explanation:
So, taking the ratio of the time taken by Henry to the time taken by Gavin is: (36 mins/ 60 mins) = (36/60) = 3:5 [Taking minutes as the common unit for both of the cases.] Thus the ratio is 3:5 in simplest form.
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]
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

The rock is dropped into 89KM deep canyon on a unknown planet it takes .99 minutes for the rock to hit the bottom of the canyon find the acceleration due to gravity on this planet
Can anyone help me please with this question
Answer:
Approximately [tex]50\; \rm m \cdot s^{-2}[/tex], assuming that air resistance is negligible and that the rock was released with zero initial velocity.
Step-by-step explanation:
Let [tex]g[/tex] denote the gravitational acceleration on this planet.
Let [tex]x[/tex] denote the displacement of this rock during this fall. Let [tex]t[/tex] denote the duration of this fall. Assume that the rock was released with an initial velocity [tex]v_{0} = 0\; \rm m \cdot s^{-1}[/tex].
Assume that the air resistance is negligible (such that gravity is the only force on this rock). The acceleration [tex]a[/tex] of the rock during the fall would be constantly equal to the gravitational acceleration [tex]g[/tex].
Since the acceleration of the rock during the fall was constantly [tex]a = g[/tex], the following SUVAT equation would apply:
[tex]\displaystyle x = \frac{1}{2}\, a \, t^{2} + v_{0}\, t[/tex].
Rearrange this equation to find an expression for acceleration [tex]a[/tex]:
[tex]\begin{aligned}a &= \frac{x - v_{0}\, t}{t^{2} / 2}\end{aligned}[/tex].
Convert the height and duration of this fall to standard units:
[tex]\begin{aligned}h &= 89\; \rm km \times \frac{10^{3}\; \rm m}{1\; \rm km} \\ &= 8.9\times 10^{4}\; \rm m\end{aligned}[/tex].
[tex]\begin{aligned}t &= 0.99\; \rm min \times \frac{60\; \rm s}{1\; \rm min} \\ &= 59.4\; \rm s\end{aligned}[/tex].
Substitute in the values to find the value of acceleration [tex]a[/tex]:
[tex]\begin{aligned}a &= \frac{x - v_{0}\, t}{t^{2} / 2} \\ &= \frac{89000\; \rm m}{(59.4\; \rm s)^{2} / 2} && (\text{Note that $v_{0} = 0\; \rm m\cdot s^{-1}$.}) \\ &\approx 50\; \rm m\cdot s^{-2} \end{aligned}[/tex].
By the assumptions above, the acceleration of this rock during this fall would be equal to the gravitational acceleration on this planet. Thus, [tex]g \approx 50\; \rm m\cdot s^{-2}[/tex] on this planet.

What linear function in form y=Mx+b for the line passing through (4.5,-4.25) with y-intercept 2.5
For us to write the equation for this line, we need to (1) find the slope of the line, and (2) use one of the points to write an equation:
The question gives us two points (one of which is the y-intercept), (4.5,-4.25), and (0, 2.5), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (2.5 - (- 4.25)) ÷ (0 - 4.5)
= −1.5
Finding the Equation
Now that we know the slope and the y-intercept, we can write the equation of the line in the point-slope form (y = mx + b)
y = −1.5x + 2.5

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 ?
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

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?
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
Nick and Charlie were each trying to solve 3x+9=4x−5. Describe the first step they each make to the equation.
Drag and drop the correct response to the space
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?
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".
