Consider functions h and k. this is a chart btw x / -3 / 0 / 1 / 2 / 4 / k(x) / -1 / 2 / 3 / 4 / 6 / What is the value of x when (k o h)(x) = -1 A. 1 B. 4 C. 2 D. -3

step-by-step :

the one below it is a function

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
