Answer:
Should be 4.
Step-by-step explanation: Here's why.
First off, use the given formula for determining the slope: m= . You will need this formula.
Second, label all your points with the right variable. For example,
0 = x1 / 0 = y1 / 2 = x2 / 8 = y2
Once completed, you've set up your problem and now you're ready to solve. Replace the formula with all the numbers. Make sure they're in the right place.
Here's how it should look:
m =
From here, you will subtract the numerator and the denominator.
m = =
Be sure to simplify it. When simplified, it goes down to 4.
Good luck! I have attached my work for you so that it's easier to understand.
Answer:
5p + 2(p-2)
simplified to: 7p-4
Step-by-step explanation:
Q. states that shop opens for p hours on weekdays
this means that to find the total number of hours on weekdays it would be 5 times p, thus 5p
On weekends, "shop opens 2 hours less" , which means 2 hours less than p.
Thus hours for both saturday and sunday
2(p-2)
Total would be adding those two together
5p + 2(p-2)
expand 2(p-2) = 2p-4
thus, 7p-4
The number of parents is c -9 since there are 9 more children than parents
And we know that the total number of people in the room is 25 so:
c + c-9 = 25
or
2c - 9 = 25
We can then solve for c
2c = 34
c = 17
