A motor scooter travels 20 mi in the same time that a bicycle covers 8 mi if the rate of the scooter is 4 mph more than twice th

aleksandr82 [10.1K]

We observe that 20 is 4 more than twice 8. This suggests the time is 1 hour and the rates are

... scooter: 20 mi/h

... bicycle: 8 mi/h

_____

You can let b represent the rate of the bicycle in miles per hour. Then we have (for time in hours and distance in miles) ...

... time = distance/speed

... time = 20/(2b+4) = 8/b

... 20b = 8(2b+4) = 16b +32

... 4b = 32

... b = 8

The rate of the bicycle is 8 mph; that of the scooter is 2*8+4 = 20 mph.

WILL GIVE BRAINLIEST, 5/5 RATING, AND FAVORITE.

Answer:

$y = -\frac{1}{2}x + 2$

Step-by-step explanation:

Assume this is function is a straight line, consider the equation of the straight line: $y=mx + c$

To find the gradient of the equation, we use any two coordinates from the table. $(x_1,y_1) = (6,-1)\\(x_2,y_2) =(2,1)$

$m = \frac{y_1 - y_2}{x_1 - x_2}\\\\m = \frac{1-(-1)}{2-6}\\\\m=\frac{2}{-4} \\\\m=- \frac{1}{2}$

We substitute the value of m in the equation:

$y =mx+c\\y = - \frac{1}{2} x + c\\\\$

To find c, we use the leftover coordinates, (4,0) in the equation above:

$y = -\frac{1}{2}x+c\\\\0 = -\frac{1}{2} \times 4+c\\\\0 = -2 + c\\\\c=2\\\\$

Substitute this value of c in the equation to get the function:

$y = -\frac{1}{2}x + 2$
