A circle that contains all the vertices of a polygon - circumscribed
Answer:
y=1/2x+13
Step-by-step explanation:
The slope-intercept form is: y=mx+b, where m is the slope and b is the y-intercept of the line. First, you have to calculate the slope using the following formula:
m=y2-y1/x2-x1
You have two points: (6, 16), (10,18) as the chores are the independent variable which is x, and the money is the dependent variable which is y.
Now, you can replace the values in the formula:
y2=18
y1=16
x2=10
x1=6
m=(18-16)/(10-6)
m=2/4
m=1/2
Now, you use the point-slope formula:
y-y1=m(x-x1)
You have to replace the value of the slope and one point and solve for y:
y-16=1/2(x-6)
y-16=1/2x-3
y=1/2x-3+16
y=1/2x+13
According to this, the answer is that the equation for his allowance in slope-intercept form is: y=1/2x+13.
3 1/2 miles = 7/2 miles
1/2 hours= 30 minutes
So,
In 30 mins, travelled 7/2 miles
In 1 min, travelled 7/2 ÷ 30= 7/2× 1/30 = (7×1)/(2×30) = 7/60 miles
In 60 mins, travelled (7×60)/60 miles = 420/60 miles = 7 miles.
Hence, the speed is 7 miles per hour.
