Mariko says that the graph that passes through (-3,-3), (-3,0), and (-3,3) represents a
linear function. Is she correct? Explain your reasoning.
Answer:
The graph that passes through (-3,-3), (-3,0), and (-3,3) does not represents a linear function.
Step-by-step explanation:
The graph that passes through (-3,-3), (-3,0), and (-3,3) does not represents a linear function. Because if we tried to find the slope for either two pairs of these coordinates. The slope would equal infinity
Lets say we find the slope of (-3,-3) and (-3,0)
[tex]\frac{-3-0}{(-3)-(-3)} =\frac{-3}{0}[/tex] Slope = [tex]\infty}[/tex]
Now lets say we find the slope of (-3,0) and (-3,3)
[tex]\frac{0-3}{(-3)-(-3)} =\frac{-3}{0}[/tex] Slope = [tex]\infty[/tex]
So now we can see that both lines of each slope is parallel to the y-axis which means that the lines a Undefined Slope (also known as Infinite Slope).
Point R is the midpoint of line QS. R is located at (5, -7.5) S is located at (-1,-13) What is the location of Point Q?
Answer: ( 11, -2 )
Step-by-step explanation:
The mid point of a line is calculated using the formula:
M = ([tex]\frac{x_{1}+x_{2}}{2}[/tex] , [tex]\frac{y_{1}+y_{2}}{2}[/tex] )
From the question , the mid point is already given , substituting , we have :
(5 , - 7.5 ) = ([tex]\frac{x-1}{2}[/tex] , [tex]\frac{y-13}{2}[/tex] )
Equating the x component to x and the y component to y , we have
5 = [tex]\frac{x-1}{2}[/tex]
x - 1 = 10
x = 11
Also
- 7.5 = [tex]\frac{y-13}{2}[/tex]
-15 = y - 13
-15 + 13 = y
Therefore : y = -2
Therefore : the location of point P is ( 11, -2 )

C.28 x 375 = m; m = 10,500 grams
D.28 x 375 =m; m = 11,500 grams
Answer:
Step-by-step explanation:
each box is 375 grams...and there are 28 boxes
total mass(m) = 28 * 375 = 10,500 grams
The weight of all the boxes of cereals can be found by the equation (C) "28 x 375 = m" and the weight is 10,500 grams.
What are equations?Two expressions are combined by the equal sign to form a mathematical statement known as an equation. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions. For instance, the two equations 3x + 5 and 14, which are separated by the 'equal' sign, make up the equation 3x + 5 = 14.So, the total mass of all the boxes:
The number of boxes is 28.Each box weighs 375 grams.Then, calculate as follows:
375 × 28 = m375 × 28 = 10,500 gramsSo, option (C) is correct.
Therefore, the weight of all the boxes of cereals can be found by the equation (C) "28 x 375 = m" and the weight is 10,500 grams.

Let u = <-3,4>, v = <8, 2>. Find u + v.
=================================================
Explanation:
In general if
u = < a, b > and v = < c, d >
then,
u+v = < a+c, b+d >
Basically we add the x coordinates separately and the y coordinates are added separately.
----------
So,
u = < -3, 4 >
v = < 8, 2 >
u + v = < -3+8, 4+2 >
u + v = < 5, 6 >

In a triangle, the measure of the first angle is five times the measure of the second angle. The measure of the third angle is 40 less than five times the measure of the second angle. What is the measure, in degrees, of each angle?
Answer:
s = 20 F = 100 T = 60
Step-by-step explanation:
F = 5s F + s + T = 180
T = 5s - 40
I picked numbers until I found the one that worked. For me, 20 worked for the second angle.
The measure of first angle, second angle, and the third angle is 100, 20 and 60.
Given that,
In a triangle, the measure of the first angle is five times the measure of the second angle. The measure of the third angle is 40 less than five times the measure of the second angle.here we assume second angle be s, first angle be f and third angle be ttBased on the above information, the calculation is as follows:
F = 5s
F + s + T = 180
T = 5s - 40
Now
5s + s + 5s - 40 = 180
11s = 220
s = 20
F = 100
T = 100 - 40
= 60

The complete question is:
Trapezoid JKLM is shown below.
What is the length, in centimeters, of KL ?
A. 12 cm
B. 10 cm
C. 9 cm
D. 6 cm
The mentioned figure is attached.
Answer:
[tex]\large\boxed{option\text{ B. }(\overline{KL})=10cm}[/tex]
Explanation:
1. KL is the hypotenuse of a right triangle; hence, you can use Pythagora's theorem to find its length.
2. The height 8 cm is one leg of the right triangle.
3. The other leg may be found by difference:
[tex]\overline{ML} -\overline{JK}=15cm-9cm=6cm[/tex]
4. Now you can use Pythagora's theorem:
[tex]hypotenuse^2=(leg_1)^2+(leg_2)^2\\ \\ (\overline{KL})^2=(8cm)^2+(6cm)^2\\ \\ (\overline{KL})^2=64cm^2+36cm^2=100cm^2\\ \\ (\overline{KL})=10cm[/tex]
A 5000-seat theater has tickets for sale at $26 and $40. How many tickets should be sold at each price for a sellout performance to generate a total revenue of $149 comma 600?
Answer:
3,600 from $26 tickets and 1,400 from $40 tickets.
Step-by-step explanation:
Let x = number of $26 tickets and y= number of $40 tickets
x + y = 5000 ⇒ x = 5000 - y
26x + 40y = 149,600
26(5000 - y) + 40y = 149600
130,000 - 26y + 40y = 149600
14y = 19600
y = 19600/14 = 1,400
x = 5000 - 1400 = 3,600
So, 3,600 from $26 tickets and 1,400 from $40 tickets.
To determine the number of tickets sold at each price, set up a system of equations using the given information and solve for the variables.
Explanation:To determine how many tickets should be sold at each price, we can set up a system of equations using the given information.
Let's assume the number of $26 tickets sold is x and the number of $40 tickets sold is y.
The total number of tickets sold is x + y, so we have the equation x + y = 5000.
The revenue generated from $26 tickets is 26x, and the revenue generated from $40 tickets is 40y. The total revenue
is given as $149,600, so we have the equation 26x + 40y = 149600.
Solving this system of equations will give us the values of x and y.

a bookstore employee is given a 20% discount off the retail price of any book. assuming there is no tax, how many dollars does she pay for a book with a retail price of $55?
Answer:
= $ 49.5
Step-by-step explanation:
We are given;
Discount off retail price is 20%Retail price is $55Required to determine the amount paid
Taking the retail price as 100%
Then, amount paid will be (100 % - 10%) 90% of the retail price
Therefore;
Amount paid = 90% × $ 55
= 0.9 × $ 55
= $ 49.5
Thus, the employee paid $ 49.5 for the book.

The perimeter of the garden is 57.14 m and
the total area of the garden is 178.28 sq. m.
Solution:
Given length of the rectangle = 16 m
Width of the rectangle = 8 m
Radius of the semi-circle = half of the width of the rectangle
Radius = 4 cm
Perimeter of the garden is two lengths of the rectangle and 2 curve sides of the semi-circle.
Perimeter = [tex]2l+2(\frac{2\pi r}{2} )[/tex]
= [tex]2l+2\pi r[/tex]
= [tex]2(16)+2\times\frac{22}{7}\times4[/tex]
= 32 + 25.14
= 57.14 m
Total area of the garden is the area of the rectangle and area of the two semi-circles.
Area of the garden = [tex](l\times w)+ 2(\frac{\pi r^2}{2})[/tex]
= [tex](l\times w)+ \pi r^2[/tex]
= [tex]16\times8+\frac{22}{7} \times 4\times 4[/tex]
= 128 + 50.28
= 178.28 square meter
Hence, the perimeter of the garden is 57.14 m and
the total area of the garden is 178.28 sq. m.
