Fitness Classes cost £6 per person. The table shows the number of people who go to the classes on Thursday, Friday and Saturday.

Pachacha [2.7K]

Answer:

£216

Step-by-step explanation:

Cost = £6 per person
Teacher earns = 90% of total

Total number of people:

13 + 11 + 16 = £40

Total payment:

40*6= £240

Teacher earns in total per given week:

240*90/100 = £216

a new line is drawn through the point (-3,6) and perpendicular to the line with x-intercept (3,0) and y intercept (0,3) . what i

Klio2033 [76]

Answer:

The equation of the new line is $y=x+9$ or $y-6=(x+3)$

Step-by-step explanation:

step 1

Find out the slope of the line with x-intercept (3,0) and y intercept (0,3)

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{3-0}{0-3}=-1$

step 2

Find the slope of the new line perpendicular to the given line

we know that

If two lines are perpendicular,then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

$m_1*m_2=-1$

we have

$m_1=-1$ ----> slope of the given line

$m_2=1$ ---> slope of the new line

step 3

Find the equation of the new line in point slope form

$y-y_1=m(x-x_1)$

we have

$m=1$

$(x_1,y_1)=(-3,6)$

substitute

$y-6=(1)(x+3)$

$y-6=(x+3)$ ----> equation in point slope form

Convert to slope intercept form

$y=mx+b$

isolate the variable y

$y=x+3+6$

$y=x+9$

Determine if John's wages are proportional to time. If they are, determine the unit rate y/x. If not, explain why not.

Paladinen [302]

Answer:

- Student cannot determine proportionality because there is no y-intercept.

- Table and graph do not match

(Student does not realize they are based on two different people)

- Student computes x/y and not y/x (Ex. 3/27 or 2/18)

Step-by-step explanation:

-May not be able to determine Unit rate because (1, r) does not exist on the table.

-May answer “18” because it is the first point on the table.

-Unable to determine relationship between x and y values
