To find the number you must make the inequality x+10>50 so we can solve and get x>40
Answer:
u you
Step-by-step explanation:
Area= (1 side)^2
⇒ 2.25 in^2= (1 side)^2
⇒ 1 side= √(2.25) in
⇒ 1 side= 1.5 in
The length of 1 side of the base of the notepad is 1.5 inch~
It would be c 25/2
Sorry, I can actually understand what you were asking in the comments
F(x) = 1/2x +4
replace f(x) with y
y = 1/2x+4
switch x and y
x = 1/2y +4
solve for y
multiply both sides by 2
2x = y+8
subtract 8 from both sides
2x-8 = y
rewrite with y on the left side: y = 2x-8
replace y with f(x)^-1 (inverse notation)
f(x)^-1 = 2x-8
solve for f^-1(4)
replace x with 4 in the equation and solve:
2(4) -8 = 8-8 = 0
