Answer:
The answer is x=27/28
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
The solution of the expression is,
⇒ x = 27/28
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 2x - 1/4 + x/3 = 2
Now, Solve the expression as;
⇒ 2x - 1/4 + x/3 = 2
⇒ 2x + x/3 = 2 + 1/4
⇒ 7x/3 = 9/4
⇒ 7x = 27/4
⇒ x = 27/28

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?
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.

Given:
The graph of a line.
To find:
The equation of line and values of m and b. Check whether it is proportional or linear.
Solution:
From the given graph it is clear that, the line passes through (0,4) and (2,0). So, the equation of line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-4=\dfrac{0-4}{2-0}(x-0)[/tex]
[tex]y-4=\dfrac{-4}{2}(x)[/tex]
[tex]y-4=-2x[/tex]
Adding 4 on both sides, we get
[tex]y=-2x+4[/tex]
On comparing this equation with slope intercept form, i.e., [tex]y=mx+b[/tex], we get
[tex]m=-2\text{ and }b=4[/tex]
All lines are linear. If a line passes through the origin then it is proportional.
From the given graph it is clear that the line is not passing through the origin, i.e., (0,0). So, it is linear not proportional.
Therefore, the value of m is -2 and the value of b is 4. The equation of line is [tex]y=-2x+4[/tex]. The line linear not proportional because it does not passing through the origin.
Andy drove from his home to his sisters house he stayed at her house and then drove back home. please help ASAP
Answer:
a) 45 minutes
b) 100 km/hr
Step-by-step explanation:
a) It is the length of the horizontal line in the graph. It extends from 14:45 to 15:30 and that is 45 minutes.
b) Andy travels 50 km in 30 minutes (=0.5 hr), that's 50/0.5 = 100 km/hr.
As per linear equation, Andy stayed his sisters house for 45 minutes.
The average speed on his journey home is 100 km/hour.
What is a linear equation?"An equation that has the highest degree of 1 is known as a linear equation. This means that no variable in a linear equation has an exponent more than 1. The graph of a linear equation always forms a straight line."
As per the graph, Andy drove from his home to his sisters house.
Then he rested for a while there.
After that, he returned back to his home.
It is clear from the graph that, Andy stayed his sisters house
= (15:30 - 14:45) hours = 45 minutes
Again, from the graph, the distance between Andy and his sister's house is 50 k.m.
Andy return back to his home in
(16:00 - 15:30) hours
= 30 minutes
= 0.5 hours
Therefore, the average speed on his journey home is
[tex]= \frac{50}{0.5} km/hour\\= 100 km/hour[/tex]

solve for x.
6(x+4)-8x=16
Answer:
x=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6(x+4)−8x=16
(6)(x)+(6)(4)+−8x=16(Distribute)
6x+24+−8x=16
(6x+−8x)+(24)=16(Combine Like Terms)
−2x+24=16
−2x+24=16
Step 2: Subtract 24 from both sides.
−2x+24−24=16−24
−2x=−8
Step 3: Divide both sides by -2.
-2x/-2=-8/-2
x=4
Answer:
X=8
Step-by-step explanation:
First you distribute the 6 to the x and the 4 which gives you, 6x+4x-8x=16 , From there you would add 6x and 4x which gives you 10x. Then you would subtract 8x and that gives you 2x. Now you have 2x=16, then you divide by 2 on both sides. That gives you x=8
