The answer is 1561 yuans and 27 jiao.
Answer:
The equation in the slope-intercept form will be:

Step-by-step explanation:
Given
As we know that the equation of a line in point-slope form is

substituting the values m = 6 and point = (1, 3)

Writing the equation in slope-intercept form

where m is the slope, and b is the y-intercept
so the equation of the line in slope-intercept form becomes

add 3 to both sides


Therefore, the equation in the slope-intercept form will be:

Answer:
21/7= 3
Step-by-step explanation:
Answer:
a.) 20 kilometers
b.)1.67 hours
Step-by-step explanation:
a.) formula= speed =distance/time
Speed= 10km/hr
Distance=unknown
Time=2hrs
Therefore from formula, distance=speed x time
10 x 2
20 kilometers
b.) If average speed is increased by 2km/hr then
total speed= 2+10=12km/hr
Distance remains constant therefore distance= 20km
Therefore time =distance/speed
20/12
= 1.67 hours
Answer:
(x) = 
Step-by-step explanation:
Let y = f(x) and rearrange making x the subject
y = 4x ( divide both sides by 4 )
x = 
Change y back into terms of x
(x) =
