Domain : (1,2,3........)
range: (510, 520, 530........)
domain: its like input of the function. like in this function of k(x)
x is miles and miles can't be negative so negative number can't be input of this function. just ask what are all the possible value that x can take
Range is output of function.
like: k(1)= 510 and so on
what comes out (the Range) depends on what we put in(the Domain)
Range should have single value.
I think………
We first get juniors for females
20% of 40%
20%*40%=8%
Then juniors for males
Get the percentage of males first
100%_40%=60%
Juniors for males
30%of60%
30%*60%=18%
Then all members who are juniors
8%+18%=26%
I don’t know if this is correct this is what I just think
3x + y = -3
Substitute y = x + 5 in the ‘y’ spot in the 3x + 7 = -3 equation
3x + y = -3
3x + x + 5 = -3
combine liked terms
4x + 5 = -3
-5 on both sides
4x = -8
/4 on both sides
x = -2
Answer:
x = -2
Answer:
If I did my math correctly, They washed 15 cars on Sunday.
Step-by-step explanation:
50 cars = 100%
Therefore 1 car would be 2% because 50 is half of 100.
So because 30% would be 2 times the amount of cars, we divide 30 by 2, giving us 30% = <u>15 cars on Sunday</u>
With this information, we can take away 15 from 50 giving us 35 cars which is equal to 70% on Saturday
Here is some extra data:
10% = 5 cars
20% = 10 cars
30% = 15 cars
40% = 20 cars
50% = 25 cars
60% = 30 cars
70% = 35 cars
80% = 40 cars
90% = 45 cars
100% = 50%
Basically, every 10% is +5 cars
