If h(x) = 5x and k(x) = 1/x
Then (k o h) (x) = k ( h(x) ) = k(5x) = 1/(5x)
2) If h(x) = 5 + x and k (x) = 1/x
Then (k o h)(x) =k ( h(x) ) = k (5+x) = 1 / [5 + x]

Answer:
x = -2
Step-by-step explanation:
Picture attached, shows a weighing scale in the balanced form,
So weight of elements on the left = Weight of the elements on the right
Left side of the scale = weight of x + weight of 1
= x(2) + 1(6)
= 2x + 6
On the right side of the scale = Weight of (-x) + weight of (-1)
= (-x)(2) + (-1)(2)
= -2x - 2
Since, both the sides are balanced,
Therefore, equation which models the situation is,
(2x + 6) = -(2x + 2)
(2x + 6) + (2x + 2) = 0
4x + 8 = 0
4x = -8
x = -2
Answer:
Ok, so what happend was 4 was added to every x, the whole thing was multiplied by -1 and -2 was added to the whole function
so
adding 4 to every x shifts the graph to the left 4 units
multiplying the whole function by -1 reflects it over the x axis
adding -2 to the whole function moves it down2 units
so that would be the first option
Step-by-step explanation:
To find the reciprocal of a mixed number, we first convert it to an improper fraction. 1 1/5 = 5/5 + 1/5 (remember that 1 whole would have the same numerator and denominator) = 6/5.
The reciprocal is this number flipped, so 5/6.
To find the sum of 1.25 and -1 3/4, we will convert the decimal to a fraction. 0.25 is read as "twenty-five hundredths," so the fraction would be 25/100. This will simplify to 1/4, so 1.25 = 1 1/4.
1 1/4 + -1 3/4 = -2/4 = -1/2.
Now we add 5/6 + -1/2:
Find the least common denominator (LCD). 6 is the first number that both 6 and 2 will divide into evenly. This gives us 5/6 + -3/6 (we multiply 2 by 3 to get 6, so we multiply the numerator, -1, by 3 as well). This equals 2/6 which simplifies to 1/3.
