Live earns $9.50 for every two bracelets she sells. The equation y=4.75x ,where x represents the number of bracelets and y represent t total cost in dollar earned.represents this situation.what is the constant of prop rationality? What does the constant of proptionality represent in the contexts of the problem?
Answer:
Price of each bracelet = $4.75
Step-by-step explanation:
Given:
y =4.75x
In equation;
y = kx
where k is constant
So , we say that 4.75 is constant of proportionality
So price of each bracelet = $4.75

x2y4(x2 - 16) - 9y4(x4 - 16) how do i simply this?
Answer:
The simplified expression is given as
[tex]8x^2y^4(17x^2-2)[/tex]
Step-by-step explanation:
step one:
Given the expression
[tex]x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)[/tex]
step two:
First, let us open the bracket we have
[tex]x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)\\\\x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\[/tex]
step three:
collect like terms we have
[tex]x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\x^4y^4-9x^4y^4+144x^4y^4-16x^2y^4\\\\-8x^4y^4+144x^4y^4-16x^2y^4\\\\136x^4y^4-16x^2y^4\\\\\\[/tex]
step four:
we can now factor out [tex]8x^2y^4[/tex]we have
[tex]8x^2y^4(17x^2-2)[/tex]
If the measures of two angles of a triangle are 87 and 17 , what is the measure of the third angle
Answer:
76 degrees
Step-by-step explanation:
The total of the three angles in a triangle should equal 180 degrees. So to find the third angle, subtract the two given angles from 180
180 - 87 = 93
93 - 17 = 76
The third angle is 76 degrees because then all angles will add up to 180

A theater company charges $5.50 per ticket for people of all age groups. If c represents the total number of children who brought tickets and a represents the total number of adults who bought tickets, which expression best represents the total money earned by the company from the sale of tickets?
Answer:
[tex]5.50c+5.50a[/tex]
Step-by-step explanation:
Cost of 1 ticket = $5.50
Total number of children who brought tickets = c
Total number of adults who bought tickets = a
Amount earned from selling tickets to children = 5.50 c
Amount earned from selling tickets to adults = 5.50 a
Therefore,
Total money earned by the company from the sale of tickets = [tex]5.50c+5.50a[/tex]

A bag contains white,blue and red balls in the ratio 8:3:2.There are 10 red balls if 10 white balls and 10 blue balls are removed from the bag the new ratio is
Answer:
If you have 10 red balls, you have blue balls in proportion 3:2, so you have 15 blue balls. Moreover, you have white balls in proportion 8:2=4:1, so you have 40 white balls.
Removing 10 white and blue balls causes you to have 30 white, 10 red and 5 blue balls.
Since 30=5*6 and 10=5*2, the new proportion of white, red and blue balls is 6:2:1.

A chess team is ordering customized T-shirts for a competition. The table shows the cost of ordering different numbers of T-shirts. Write a
linear model that represents the cost as a function of the number of shirts
Answer:
y=8x+36
Step-by-step explanation:
Use y=mx+b. First find m, the slope.
To do that, use y2-y1/x2-x1. Use any two point combinations from the table. You can use (6,84) and (12,132).
Y2 would be 132 and Y1 would be 84, and X2 would be 12 while X1 is 6. Just look at the pointss. For example, Y2 is 132 because (12,132). 132 is in y's spot. Same goes for x.
Now that we got y2, y1, x2, and x1, we can plug it into the formula and solve.
y2-y1/x2-x1= 132-84/12-6= 48/6= 8
This means the slope is 8. Now, we need to find the y intercept.
Use y=mx+b again and use any pair of points. I'm going to use (6,84).
y=mx+b. Plug in the slope, which is 8.
y=8x+b
y=8x+b. Plug in the y. The y variable is 84 so plug that in.
84=8x+b. Same for the x. The x variable is 6 so plug that in as well.
84=8(6)+b. Now simplify it.
84=48+b. You want to isolate b to find the y intercept so move the 48 to the left side.
It's now 84-48=b. The 48 because negative because whenever you move a number to the other side, it switches its sign.
Solve.
84-48=b
36=b or b=36. So the y intercept is 36.
We now have our slope and the y intercept.
Slope: 8
Y intercept: 36
We can plug that into y=mx+b a final time.
y=8x+36
The equation of the linear model is y = 8x + 36
The standard form of a linear equation is given by:
y = mx + b
Where y is a dependent variable, x is an independent variable, m is the slope of the line (the rate of change), b is the y intercept (that is the initial value of y).
Let x represent the number of T-shirts and y represent the cost
Therefore we can use any two points to determine the linear equation to represent the model of the line in the form (x, y).
Using the points (6, 84) and (24, 228). The equation is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-84=\frac{228-84}{24-6} (x-6)\\\\y-84=8x-48\\\\y=8x+36[/tex]
The equation of the linear model is y = 8x + 36

Moesha and Keyon are mailing invitations for their wedding. They have $50 to spend and each invitation costs $1.25 to mail. The function m=50−1.25w represents the amount of money m Moesha and Keyon have left after mailing w wedding invitations. Find the zero of the function. Describe what this value means in the context of this situation.
Answer:
The zero of the equation is 40
It means the number of wedding invitations they can send based on their budget
Step-by-step explanation:
To determine the zero of the function, we simply set the dependent variable ( m in this case) to zero.
Thus, mathematically;
0 = 50-1.25w
1.25w = 50
w = 50/1.25
w = 40
So what does this mean in the context of the situation?
What it means is that the total number of people they would be able to send the mail to based on their budget is 40
Answer:
The zero of the function is at
40. This represents that after mailing 40 wedding invitations, Moesha and Keyon will $ 0 left.

2.
B В
-2
-A
The slope of AB is
different than the
slope of BC.
AB has the same slope
as AC.
Answer:
Option (C)
Step-by-step explanation:
Option (A)
Rise-run ratio from the smaller triangle = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{2}{3}[/tex]
Rise-run ratio from the large triangle = [tex]\frac{4}{6}[/tex]
= [tex]\frac{2}{3}[/tex]
[tex]\frac{2}{3}=\frac{2}{3}[/tex]
Therefore, the ratios of the rise to run are equivalent in both the triangles.
True.
Option (B)
Slope the line AC will be same as segments AB and BC which lie on the same line AC.
Slope of AC = [tex]\frac{2}{3}[/tex]
True.
Option (C)
Since, the segments AB and BC are the parts of line AC
Slope of AB = Slope of BC = Slope AC
Therefore, slope of AB and BC can not be the same.
False.
Option (D)
Since, segment AB is a part line AC, slope of both will be same.
True.
Option (C) is not true.
Answer: The slope of AB is different than the slope of BC
