Answer:
5)
<2 = 79°
<1 = 101°
<3 = 101°
6)
x = 5
y = 3
Step-by-step explanation:
5)
<2 = 79°
<1 = <3 = 180 - 79 = 101°
6)
4y - 6 = 2y
2y = 6
y = 3
2x + 4 = x + 9
x = 5
Answer:
2y+12
Step-by-step explanation:
2001 gallons used in 5 days, so the average for one day is 2001/5=400.2 gallons.
F: R → R is given by, f(x) = [x]
It is seen that f(1.2) = [1.2] = 1, f(1.9) = [1.9] = 1
So, f(1.2) = f(1.9), but 1.2 ≠ 1.9
f is not one-one
Now, consider 0.7 ε R
It is known that f(x) = [x] is always an integer. Thus, there does not exist any element x ε R such that f(x) = 0.7
So, f is not onto
Hence, the greatest integer function is neither one-one nor onto.
The answer was quite complicated but I hope it will help you.
It’s BD because it need to be the opposite ray and this one is the opposite ray so yes this is it
