Dorcas walks a distance of 18 km from home to school at a speed of 6km/h how long does she take to arrive at school?

Step-by-step explanation:

⟼ distance = 18 km

⟼ speed = 6 km/h

⟼ t = distance / speed

⟼ t = 18/6 h

⟼ t = 3h

⟼ time = 3 hours.

∴ dorkas take 3 hours. to arrive at school.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
