Answer: 2
Step-by-step explanation:
(x1,y1) = (-1,0)
(x2,y2) = (3,8)
m = (8–0)/(3-(-1))
m = 8/(3+1)
m = 8/4
m = 2
Answer:
Answer:
5x + 6
Step-by-step explanation:
(f-g)(x) is nothing but f(x) - g(x)
f(x) is |5x + 1| - 3 and g(x) is 4 so the equation is [|5x+1| - 3] - [4]
Once this is solved, the answer is 5x - 6. Since there's absolute value, remove the negative and change it to a positive to get the answer 5x + 6.
Answer:
A
Step-by-step explanation:
I know that 20 times 7 is 140 and if I take away 2 sevens that leaves 126. So 126 \div 7 = 18
First let's find the rate at which one person paint one wall. We know it takes 40 minutes for 8 people to paint 4 walls.
If we divide 40 minutes by 4 walls, we find that it takes 8 people 10 minutes to paint ONE wall. Next, we multiply 10 minutes per wall by 8 people to find how long it takes ONE person to paint ONE wall. Since it takes 8 people 10 minutes, reducing the number of people to one will increase the required time by a factor of 10. So it takes ONE person 80 minutes to paint ONE wall.
Now let's use this information to find out how long it takes 10 people to paint 7 walls. First, multiply 80 minutes by 7 since there are 7 times as much wall to paint. We now know that it takes 560 minutes for one person to paint 7 walls. Finally, divide 560 minutes by 10 people.
The answer is 56 minutes.
