Muriel says she has written a system of two linear
equations that has an infinite number of solutions. One
of the equations ofthe system is 3y = 2% - 9. Which
could be the other equation?
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
If the lines are identical, there must be an infinite number of solutions. In other words, they are the coordinate of all the points on that line.
It means the lines will be overlapping. Since lines will be overlapping, it means they are the same exact line.
Given the line
3y = 2x-9
As the system of equations has an infinite number of solutions, it means the lines must be identical.
So, the other line can be obtained by multiplying the line 3y = 2x-9 by any scalar number, let say by 2.
so
6y = 4x-18 will be another line.
Thus, the system of equations become:
3y = 2x-9
6y = 4x-18
The graph is attached below.
The graph indicates that both lines are overlapping with each other. Hence, the lines will be identical and the system of the equations will have an infinite number of solutions.

Find f (-4)
Answers
Answer:
85
Step-by-step explanation:
In this question, you would solve by plugging in -4 to x.
Solve:
f(-4) = 2(-4)² - 10(-4) + 13
= 2(16) + 40 + 13
= 32 + 40 + 13
= 72 + 13
= 85

in the following figures find the value of angle COD if angle abc is equal to 75 degree and a b is equal to CD
Answers
Angle AOB is given as 75 degrees.
O is the center of the circle so AO and CO are the same length. AB and CD are the same length, so angle COD would be the same as AOB
COD = 75 degrees.
Answer:
75°
Step-by-step explanation:
It is given that:
AB and CD are chords of the circle which are equal. Equal chords subtends equal angles at the center of the circle. [tex] \because m\angle AOB = 75\degree [/tex] [tex] \therefore m\angle COD = 75\degree [/tex]Good night, logging out !

How we can differentiate between direct proportion and inverse proportion?
Answers
Answer:
Please check explanations for answer
Step-by-step explanation:
Here, we want to differentiate between inverse and direct proportion
Let x and y be two quantities
If they are directly proportional;
x/y = k
x = ky
where k is proportionality constant
If inversely;
xy = k
In verbal terms;
For direct proportionality, when one value increase, the other too does so and vice versa
For inverse, when one value inverse, the other decrease

The Blues Festival sold 20% of tickets at a reduced price of $30 and 30% of tickets at $40 and the rest at the door for full price of $50. With 10,000 tickets sold, how much did they earn from ticket sales in dollars?
Answers
Answer:
$430,000
Step-by-step explanation:
20% of 10,000 = 2000
therefore, 2000 x $30 = $60,000
30% of 10,000 = 3000
therefore, 3000 x $40 = $120,000
50% of 10,000 = 5000
therefore, 5000 x $50 = $250,000
add all dollar amounts together to get $430,000

17.
[tex]\frac{y}{x}=\frac{1}{2}=\frac{2}{4}=\frac{2.5}{5}=\frac{3.5}{7}=\frac{1}{2}=0.5[/tex]
Equation is [tex]y=0.5x[/tex]
