Answer:
see below
Step-by-step explanation:
{(x, y) : x≥2}∩{(x, y) : y≥2}
First {(x, y) : x≥2}
A solid line at x =2 and shaded to the right
(x, y) : y≥2
A solid line at y =2 and shaded above
∩ means intersection or where they overlap
The green area is where they over lap
Answer:
8/21
Step-by-step explanation:
1- 2/7 - 1/3 = 21/21 - 6/21 - 7/21 = 8/21
Problem 1: -5^2 + 10^2
Work:
-5^2 + 10^2—> (-5 x -5) + (10 x 10) —> 25 + 100 = 125
Answer:
125
Problem 2: (2 x (-5) x 3) + 3^3
Work:
(2 x (-5) x 3) + 3^3 > (-25 x 3) + 3^3 —> -75 + 3^3 —> -75 + 27 —> 48
Answer:
48
Ok to figure out if one is an inverse function, you plug in y for x and substitute f(x) with x and solve for y.
We only have to do this for 1 of the functions so we will take f(x)
x = 5y +1/y
I’m not sure you can solve for y here therefore g(x) is not an inverse function of f(x)
