Answer:
f(1)=13
f(-9)=88
f(0)=0
f(-15)=20
The above mentioned are false statements
Step-by-step explanation:
f(1)=13 : false because "13" is out of range -40≤f(x)≤-10
f(-9)=88 : false because "88" is out of range -40≤f(x)≤-10
f(0)=0 : false because "0" is out of range -40≤f(x)≤-10
f(-15)=-20 : false because "-15" is out of domain -10≤x≤20
3 GB every month..... 21+3=24+3=27+3=30....so 3 GB
Answer:
First mechanic: 20 hours
Second mechanic: 15 hours
Step-by-step explanation:
First we create two equations where:
x - hours of first mechanic
y - hours of second mechanic
x+y=35
115x+45y=2975
Then, we multiply both sides of the first equation by 45, and then subtract it from the second equation:
45x+45y=1575
|115x+45y=2975
-|45x+45y = 1575
70x = 1400
x=20 hours
Now we know for how many hours the first mechanic worked. Now we just need to subtract that from the combined total to find the second mechanic's hours:
35-20=15 hours
