Consider y =f(x)=-3x+2 . Using space below, determine the equation that represents the inverse f(x)
Answers
Answer: [tex]f^{-1}(\text{x}) = \frac{2-\text{x}}{3}[/tex]
Explanation:
Swap x and y, then solve for y to get the inverse.
[tex]f(\text{x}) = -3\text{x}+2\\\\\text{y} = -3\text{x}+2\\\\\text{x} = -3\text{y}+2\\\\\text{x}-2 = -3\text{y}\\\\\text{y} = \frac{\text{x}-2}{-3}\\\\\text{y} = \frac{2-\text{x}}{3}\\\\f^{-1}(\text{x}) = \frac{2-\text{x}}{3}\\\\[/tex]
Suppose ABCD is a parallelogram. Find the value of x and y.
Answers
answer:
x = 4
y = 19
step-by-step explanation:
we know that this is a parallelogram, so opposite sides are equalthis is one of the properties of a parallelogramtherefore,
segment AB = segment DC and segment AD = segment BC
now plug in the expressions according to what we know (& solve)AB = DC
5x - 13 = 9x - 29
-13 = 4x - 29
16 = 4x
x = 4
AD = BC
3y - 11 = 2y + 8
y - 11 = 8
y = 19

Answers
Answer:
If you're asking how many books there are its 86.
Step-by-step explanation:
If each book is 1/2 thick that means there are 2 books per inch.
Because there are 43 inches you're going to multiply by 2.
43(2)= 86.

The table shows the ratio between the number of tickets ordered and their cost: Number of Tickets Cost (dollars) 5 20 7 28 9 36 Find equivalent ratios when the number of tickets ordered is 1, 2, and 3. Write them as ordered pairs in the form (x-coordinate, y-coordinate). Starting from the origin, explain how to plot the three equivalent ratios on a coordinate grid. (10 points)
Answers
9514 1404 393
Answer:
(1, 4)(2, 8)(3, 12)Step-by-step explanation:
The ratios all have ...
first number : second number = 1 : 4
Using first numbers of 1, 2, 3, the second numbers can be found by multiplying these by 4. (1, 4), (2, 8), (3, 12)
__
You plot these (x, y) points the same way you plot any point on a coordinate grid. The first (x) value is the horizontal distance from the vertical axis. Positive is to the right. The second (y) value is the vertical distance from the horizontal axis. Positive is up.
__
Of course, the origin is where the horizontal and vertical axes meet. It can be convenient to find one of the coordinates on its respective axis, then use the other coordinate to find the point at the desired distance from that axis.
Usually, you would choose the axis on the basis of how easy it is to determine exactly where the coordinate lies. If the y-axis is marked every 5, for example, it might be hard to determine where a multiple of 4 will lie. Locating the x-coordinate on the x-axis may be an easier way to start.

Step-by-step explanation:
Since LM = 9 and ST = 6 and those are corresponding sides, the ratio of any side from [tex]\triangle{PLM}[/tex] and its corresponding side from [tex]\triangle{UST}[/tex] is 9 to 6 which can be expressed as the fraction 9/6 or 3/2.
LQ and SR are corresponding segments, so set up two ratios.
[tex]\frac{LQ}{SR}=\frac{3}{2}\\\\\frac{x-1}{x-2}=\frac{3}2}[/tex]
Now "cross-multiply" (using what you may have seen called the Means-Extremes Property).
[tex]2(x-1)=3(x-2)\\\\2x-2=3x-6\\\\4=x[/tex]
Now put in 4 for x in the expression for LQ.
[tex]LQ=x-1=4-1=3[/tex]

How to find the focus of a parabolaThe standard formula of a parabola is given as:
y² = 4ax
Given a parabola represented by the equation x² = -20y
Determine the focus
The standard equation of the parabola facing downward is 4p(y-k)=(x-h)^2 where (h, k) is the focus.
Comparing with the given equation, the focus will be at (0, -5)

How to obtain the equation for the line of fit?The equation for the line of fit is obtained inserting the points of the data-set into a linear regression calculator.
Given:
From the scatter plot, the points are given as follows:
(1, 5.4), (2, 5), (3, 4.6), (4, 4.9), (5, 4.1), (6, 3.9), (7, 3.6), (8, 3.3).
Inserting these points into the linear regression calculator, we get
y = -0.29x + 5.67.
Now, for x= 10 year
y = -0.29(10) + 5.67 = 2.77 minutes.
which is closest to 2.83 minutes.

A bag drawing contains 2 red balls and18 green a ball is chosen at random from the bag
Answers
Probability of drawing a red ball:
Total number of balls = 2 + 18 = 20
number of red balls = 2
number of green balls = 18
total number of favourble outcomes = 2
probability = number of favourable outcomes/number of total outcomes.
= 2/20 = 1/10
Therefore probability of drawing a red ball is 1/10.
Probability of drawing a green ball:
total number of balls = 2 + 18 = 20
number of green balls = 18
number of red balls = 2
total number of favorable outcomes = 18
probability = number of favourable outcomes/number of total outcomes.
= 18/20 = 9/10
Therefore probability of drawing a green ball is 9/10.

If you could take one sample from the mystery bag in order to make a prediction, would you rather draw a sample of 10 marbles or a sample of 20 marbles. Explain your choice by referring to the representations of the two distributions.
Answers
I would choose to draw a sample of 20 marbles in order to make a more accurate prediction.
How to illustrate the sample?In general, it is generally better to draw a larger sample if you are trying to make a prediction. This is because a larger sample will provide more information and will therefore lead to a more accurate prediction.
For example, imagine that you are trying to predict the proportion of red marbles in a bag based on the samples that you draw. If you draw a sample of 10 marbles, there is a good chance that the proportion of red marbles in your sample will be different from the true proportion of red marbles in the bag.
However, if you draw a sample of 20 marbles, the proportion of red marbles in your sample will be more likely to be closer to the true proportion of red marbles in the bag.
