Since you know that the equation of straight line is y=Mx + c
Where m mean gradient , and c means intercept
We don’t know our intercept neither do we know our gradient
So we have to find these to get our equation
Therefore, to find m( gradient) from the table
We are going to use the formulae for gradient which is
M=y2-y1 / x2-x1
I.e from the table
M= 23-15 / 4-2
M=8/2
M=4
Therefore how gradient is 4
First one:
3x+5<23
3x<18 (subtract 5 from both sides)
x<6
So A: less than 6 cars
Second one:
3(x-4)+5(2x+1)
3x-12+10x+5 (distribute)
So the answer is C
Hope this helps
Answer:
100 students chose all three
Step-by-step explanation:
first make a row for each subject and put how many students chose said subject. then subtract the number of students that chose both from the total amount of a subject
