Answer:
26x+61
Step-by-step explanation:
Elliott's bed -> 75 in
Elliott before -> 5 ft 11 in = 71 in
Elliott after -> 71 + 6 = 77 in
77 - 75 = 2 in
Elliott's bed is shorter than him by 2 inches.
Answer:
-4
Step-by-step explanation:
8-5= 3
x/3= 4
12/3=4
-16+12=-4
Answer:
no
Step-by-step explanation:
Assuming the wall makes a 90-degree angle with the ground, the ladder is the hypotenuse of a right triangle whose legs are the ground distance, the wall height, and whose hypotenuse is the ladder length.
The hypotenuse of a right triangle must be longer than either side. If one side is length 13 and one side is length 5, the hypotenuse must be about 13.93. A 13-ft ladder will not do.
Answer:
Not inverse between each other
Step-by-step explanation:
To determine if two mathematical functions are inverse between each other, you should verify that: for function f(x) and h(x)
- f(h(x)) = x for all and each x within h domain
- h(f(x)) = x for all and each x within f domain
So we should verify that we will obtain the same result when doing f(h(x)) and h(f(x)), if so, then both function are inverse between each other
f(x) = (2-1)/2x h(x) = -2x + 4
f(h(x)) = (2-1)/2(-2x+4) h(f(x)) = -2[(2-1)/2x] + 4
f(h(x)) = (2-1)/-4x+8 h(f(x)) = [(-4+2)/2x] + 4
f(h(x)) = (2-1)/8-4x h(f(x)) = (-4+2+8x)/2x
h(f(x)) = (8x-2)/2x
As we finally found that f(h(x)) ≠ h(f(x)), so both functions are not inverse between each other
