Answer:
Step-by-step explanation:
First multiply z by -6, obtaining -6z, and then multiply -1 by -6, obtaining
-6z + 6 (a product)
The initial value equals the y-intercept. The equation is in the slope-intercept formula where b is the y-intercept. The answer would be -7. [Note: If it's + in front of the b value, it's a positive value (b). If - is in front of it, it's a negative value (-b).]
It took him 1 hour and 30 mins .
He needs to go 15 miles. It takes him 1 hour to get 10 miles. After 1 hour has passed he still needs 5 more miles to go. 5 miles is half of 10 so half of 1 hour is 30 mins. 1 hour + 30 mins is 1 hour and 30 mins. (It took him 1 hour 30 mins)
