0.04(30h) is the part. Because 0.04 represents 4%, we know that it should be the tax rate. 30h represents the cost for every hour, so we know that that's not the correct answer.
To answer this problem, given the speed is 7mph and the distance is 11.2mile and its obvious that we can divide the given distance by the speed. The answer is 11.2/7= 1.6 hours
Do what it says; solve one of them for y. I'll do the first one:
Now that we know what y is, we can substitute that into the other equation:
Now distribute:
And simplify:
Now that we know what x is, just put that value into either equation to find y, I'll do the first one since we already solved for y:
And simplify:
Now just put the values into a coordinate pair:
Answer:
Step-by-step explanation:
The rate of change, slope, m is
m=(y2-y1)/(x2-x1), we have points (4,5) and (21,39) so
m=(39-5)/(21-4)
m=34/17
m=2
So the rate of change is 2
Answer:
8/7
Step-by-step explanation:
The number on the left is bigger than the number on the right. It is like the fraction is overflowing. You could turn it into 1 1/7 to make it a proper fraction.
