Let r={0, 1, 2, 3} be the range of h(x) = x - 7. the domain of h -1(x) is {-7, -6, -5, -4} {7, 8, 9, 10} {0, 1, 2, 3}

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

The steps used to solve the equation 6(2x - 11) + 15 = 21 is explained. The value of "x" is 6

Solution:

Given, equation is 6(2x - 11) + 15 = 21

We have to solve the given equations with step by step explanation.

Now, take the equation,  

6(2x - 11) + 15 = 21

Now we can solve using BODMAS rule

BODMAS means sequence of operations which are Brackets, Order, and then division, multiplication, addition and then subtraction

Now solving for brackets in given equation,

12x – 66 + 15 = 21

Now moving the term from right side to left side of expression for easier calculations we get,

12x - 66 + 15 -21 = 0

Now perform addition and then subtraction,

12x - 51 - 21 = 0

12x - 72 = 0

12x = 72

Hence the value of "x" is 6
