Answer:
Therefore the maximum number of video games that we can purchase
is 6.
Step-by-step explanation:
i) Let us say the number of video game system we can buy that costs $185
is x and the number of video games of cost $14.95 is y.
ii) The total amount we can spend on the purchase of the video game
system is $280.
iii) Now with the amount of $280 mentioned in ii) we can see that the
number of game systems that can be bought is 1.
Therefore x = 1.
Therefore the equation we can write to equate the number of video
games and video game system is given by $185 + $14.95 × y ≤ 280
Therefore 14.95 × y ≤ 280 - 185 = 95
Therefore y ≤ 95 ÷ 14.95 = 6.355
Therefore the maximum number of video games that we can purchase
is 6.
A. Does the table represent a proportional relationship?
B. If the relationship is proportional, what is the constant of proportionality?
Total wight in pounds. 12 18 30 60
Number of books. 10 15 25 50
A. Yes the table represents a proportional relationship
B. The constant of proportionality is 1.2
Step-by-step explanation:
Two quantities are proportional if:
One of them is equal to the constant times the other oneIf x and y are proportion, then y = k x, where k is constant∵ Total wight in pounds ⇒ 12 , 18 , 30 , 60
∵ Number of books ⇒ 10 , 15 , 25 , 50
- Divide each two corresponding data to check if all they give
the same constant or not
∵ 12 ÷ 10 = 1.2
∵ 18 ÷ 15 = 1.2
∵ 30 ÷ 25 = 1.2
∵ 60 ÷ 50 = 1.2
- That means the total wight is equal to constant times the
number of books
∴ Total wight = 1.2 Number of books
∴ The total wight and the number of books are in a proportional
relationship
A. Yes the table represents a proportional relationship
∵ Total wight = 1.2 Number of books
∴ The constant of proportionality = 1.2
B. The constant of proportionality is 1.2

Write an equation in slope-intercept form for the line perpendicular to y=−4x+1 that passes through the point (−7,1)
Answer:
all work is shown and pictured
Final answer:
To find the equation of a line perpendicular to y = -4x + 1 that passes through the point (-7, 1), determine the slope, use the point-slope form, and convert it to slope-intercept form.
Explanation:
To find the equation of a line perpendicular to y = -4x + 1 that passes through the point (-7, 1), we first determine the slope of the perpendicular line. The slope of a line perpendicular to a line with slope m is the negative reciprocal of m. So, the slope is 1/4. Next, we use the point-slope form of a line y - y₁ = m(x - x₁) and plug in the point to find the equation in slope-intercept form, y = mx + b.
Plugging in (-7, 1) and slope 1/4 into the point-slope form, we get y - 1 = (1/4)(x + 7). Simplifying gives us y = (1/4)x + 2. Hence, the equation of the line perpendicular to y = -4x + 1 that passes through the point (-7, 1) is y = (1/4)x + 2.

Answer:
Vertical lines
Step-by-step explanation:
Linear relations are not functions when they appear graphically are vertical lines.
What is function?
" Function is defined as when the relation between variables are such that each input has one and only one output."
According to the question,
Linear relation are defined as y = ax + b
A. Horizontal lines is expressed by equation y = 0x + b
For each x = 0 , 1, 2, 3, .... value of y = b. For each input single output 'b' is defined.
Horizontal lines represent the function.
B. Linear relation represents straight line .
For example y = 2x +3
For each x we have single output y.
Therefore linear relation represents function.
C. Vertical lines x = k , here for x=k there are many outputs y = 0,1, 2, 3....
Vertical line does not represent function.
Hence, linear relations are not functions when they appear graphically are vertical lines.

3/-1-3HELP!! which is the measure of wx shown in the diagram below
Answer:
A. 25°
Step-by-step explanation:
We are given a circle and two intersecting lines of circle meets at s and form an angle 34° at S.
Also, we have W and X points on circle that form a minor arc and T and R makes a major arc of angle 93°.
In order to find the value of minor arc WX, we need to apply following formula:
Subtends angle on intersection of lines = [tex]\frac{Major Arc- Major Arc} {2}[/tex]
Plugging values in above formula, we get
34= [tex]\frac{93 - x }{2}[/tex]
On cross multiplication, we get
34 × 2 = 93-x
68 = 93 -x
x = 93-68
x= 25.
Therefore, measure of arc WX = 25°.Hope this helps and you understand !!!!!!

Teri bought 360 rubber band 2 make a bracelet
15% of the bands were white and the rest were red. After using 140 bands to make her 1st bracelet , 20% of the remaining bands were white
How many red bands did teri use on the bracelet
Answer:
Step-by-step explanation:
No. of white bands = 15% of 360 = (15/100)*360= 54
No.of red bands = 360 - 54 = 306
No. bands remaining = 360 - 140 = 220
No. of remaining white bands = 20% of 220= (20/100)*220 = 44
No. of remaining red bands = 220 - 44 = 176
No. of red band used = No.of red bands - No of remaining bands
= 306 - 176 = 130

1. If two nonvertical lines are parallel, what do we know about their slopes? If two lines are perpendicular and neither is parallel to an axis, what do we know about their slopes? Why must the lines be nonvertical?
Non-vertical parallel lines have equal slopes, while slopes of non-vertical, non-horizontal perpendicular lines are negative reciprocals of each other. Vertical lines are defined as having an infinite slope, thus they must be non-vertical to consider their slopes.
Explanation:When considering the slopes of lines on a graph with perpendicular axes, like the x-axis and the y-axis, we can draw several conclusions about parallel and perpendicular lines. If two non-vertical lines are parallel, their slopes are equal, because the tilt of the lines with respect to the horizontal axis is the same. For example, if we have two equations of lines in the form y = mx + b, where m represents the slope and b represents the y-intercept, parallel lines would have the same value of m.
If two lines are perpendicular and neither line is parallel to an axis, then their slopes are negative reciprocals of one another. This holds true because the product of the slopes of two perpendicular lines is -1. For example, if the slope of one line is a, the slope of the line perpendicular to it will be -1/a.
It is necessary for the lines to be non-vertical because a vertical line does not have a well-defined slope; its slope is considered infinite. Therefore, the definition of perpendicular lines in terms of slope only applies to non-vertical lines.

(889 x 27) + 50 is
than 889 x 27
Final answer:
The expression (889 x 27) + 50 is greater than 889 x 27, because adding 50 to any product will always result in a larger number.
Explanation:
The student's question is asking to compare the result of the expression (889 x 27) + 50 with 889 x 27, without actually calculating the precise values.
First, let's evaluate the structure of the expressions. When we have an expression of the form (a x b) + c, adding any number c to the original product of a and b will always result in a value greater than the original product. This is a basic property of arithmetic progression.
Based on this property, we know that (889 x 27) + 50 is definitely greater than 889 x 27 because we are adding a positive number (50) to the original product, hence the sum must be larger.

Create a dot plot for the data in the table. Hover over each number on the number line. Then click and drag up to create the dots.

2.25 : 3 dots up
2.5 : 4 dots up
2.75 : 4 dots up
3 : 2 dots up
3.25: 0 dots up
3.5 : 2 dots up
The dot plot for the considered data is plotted based on how many times each observation occured (given by frequencies), as plotted in the image attached.
How does dot plot works?Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in number line. Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing we did.
Thus, suppose if we observed the value 'x', then we will make a dot above 'x'. If there is already a dot over 'x', then we will make a new dot over that dot.
If instead of only observations, the table of unique observation and frequency is given, then we plot dots that many times as the count written in the frequency table.
Thus, if its written that the value 2 has 3 has its frequency, then we plot 3 dots one over the other above the value 2 in the horizontal axis.
For this case, we're given the unique observation to frequency table as:
Diameter (cm) Frequency
2 3
2.25 3
2.5 4
2.75 4
3 2
3.5 2
That means, over the value 2, plot 3 dots (as diameter 2 occured 3 times), and so on, over the value 3.5, plot 2 dots.
