Please help I don’t understand

Firlakuza [10]

Answer:

1/2

Step-by-step explanation:

y = mx + b

the "m" is the slope

and the b is the y-intercept

as you can see from the equation y = 1/2x + 3

the 1/2 substituted the m which is the slope

so the slope of the line is 1.2

Which of the following is the inverse of the function given below?

Mademuasel [1]

Rearrange so x is the subject:-

(im assuning the f unction f(x) = (x + 2) / 7):-

f(x) = (x + 2)/7

7f(x) = x + 2

x = 7f(x) - 2

replace f(x) by x and x by another function

f = 7x - 2

Its D

Blizzard [7]

C is your answer because of the fact that it sets the proportion needed to answer the question which the question would be how many miles can she drive on 9 gallons of gas.

so the correct proportion is 54    x
                                            _      _
                                           3.5    9 ! Then your answer would be she can drive about 139 miles if she has 9 gallons of gasoline.     : )

Give one example of when you would make a frequency table to solve the problem

RideAnS [48]

Answer:

Consider a class in which there are 40 students .There is a Mathematics test of 50 marks .Two students were absent.The Duration of test was for one and half an hour.

So Marks of students according to their roll number are 12,8,4,20,25,36,2,29,35,39,5,48,43,37,38,29,17,15,15,25,31,32,26,28,27,24,2,15,34,,50,46,48,37,28,26,45,49,24.

So in this case it would be better to prepare frequency polygon by selecting a class interval.

Class interval = 0-5,5-10,10-15,15-20,20-25,25-30,30-35,35-40,40-45,45-50.

Or 0-10,10-20,20-30,30-40,40-50.

or you can make class interval by yourself.
