Answer: FIRST OPTION.
Step-by-step explanation:
First, it is important to remember that the Slope-Intercept form of the equation of a line is the shown below:
Where "m" is the slope of the line and "b" is the y-intercept.
By definiton, given a System of Linear equations, if they are exactly the same line, then the System of equations have Infinely many solutions.
In this case you have the following System of Linear equations given in the exercise:
So, since you need the system has Infinite solutions, you know that the slope and the y-intercept of both lines must be equal.
Therefore, you can identify that the value of "a" and "b" must be the following:
So the Linear System would be the shown below:

Answer:
40%
Step-by-step explanation:
140/350=0.4
0.4 x 100=40
Answer:
Step-by-step explanation:
Original price that she paid for the dish washer is £240. She wants to sell it and make a profit of 25%. It means that price at which she would make a profit of 25% is
240 + 25/100 × 240 = 240 + 60 = 300
To determine the price tag of 40% discount and that would still ensure that she makes £300,
Let x represent the price tag in £. It means that a discount of 40% on £x would be 300. A discount of 40% on £x is expressed as
x - (40/100 × x) = x - 0.4x = 0.6x
So 0.6x = 300
x = 300/0.6 = 500
So the price tag will be £500
Answer:
B. 17.8
Step-by-step explanation:
c^2 = 14^2 + 11^2 (Pythagoras theorem)
c^2 = 196 + 121
c^2 = 317
c = √317
c = 17.8
