47.317 or about 47.32kph is the average speed.
You could set this up as a standard ratio to help visualize how to solve this problem. For every 194 kilometers, 4.1 hours has passed in meaning the ratio would be 194:4.1. Next find what side would make 4.1 would change into 1 so you would do 4.1 divided by 4.1 which will give you 194:1. But with a ratio you need to divide on both sides of the ratio. So do 194/4.1 which would equal to about 47.317.
Answer: option d.
Step-by-step explanation:
Based on the information given in the problem, you know that:
You also know that:
Substitute values. Then, you obtain:
Apply square root to both sides. Therefore, you obtain:
Answer:
(a) (4, 5)
Step-by-step explanation:
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . where m is the slope and (h, k) is the point
Comparing this to
y -5 = 1/2(x -4)
we see that k=5, m=1/2, h=4. Then the point is ...
(h, k) = (4, 5)
C. y-2=1/2(x+5)
if you bring over the -2 you will get y=1/2(x+5)+2 ... the number outside the parentheses stays they way it is and it’s the y. However, the number inside the parentheses becomes the opposite of what it is and is the x.
