Find the domain of f(x)= sqrt2-9x

Answers

Answer 1
Answer:

f(x) = √(2 - 9x)

2 - 9x ≥ 0

  - 9x ≥ - 2

     (-9x)/(-9) \geq (-2)/(-9)

     x ≤ (2)/(9)

Interval Notation: (-∞, (2)/(9)]

1. If the expression 9y − 5 represents a certain number, which of thefollowing could NOT be the translation?

a. five less than nine times y

b. five less than the sum of 9 and y

c. the difference between 9y and 5

d. the product of nine and y, decreased by 5

Answers

After examining all options, we find that each one can be represented by the expression 9y - 5. Therefore, there is no option that could NOT be the translation of the given expression.

To find the translation that could NOT be represented by the expression 9y - 5, we need to compare each option with the given expression and determine if they are equivalent or not.

The given expression is: 9y - 5

Now, let's examine each option:

a. five less than nine times y

This option can be represented as 9y - 5, so it is equivalent to the given expression.

b. five less than the sum of 9 and y

This option can be represented as 9 + y - 5, which simplifies to 9y - 5. So, it is also equivalent to the given expression.

c. the difference between 9y and 5

This option can be represented as 9y - 5, so it is equivalent to the given expression.

d. the product of nine and y, decreased by 5

This option can be represented as 9y - 5, so it is also equivalent to the given expression.

One brother eats 3/5and the other brother eat 3/10 of the cereal how much more does the other brother eat

Answers

In this question there are information's of immense importance and that can go a long way in helping to solve the given question. It is given that one brother eats 3/5 of the cereal and the other brother eats 3/10 of the cereal. The answer that needs to be found is that the amount of cereal the other brother eats more.
The amount of cereal eaten more by the other brother = (3/5) - (3/10)
                                                                                       = ( 6 - 3)/ 10
                                                                                       = 3/10
So the other brother does not eat more, but the first brother has eaten 3/10 more than the other brother.
well 3/5 is equal to 6/10
then you would subtract 6/10-3/10=3/10

-2/3a + 5/6a - 1/6

         

-2/3a + 5/6a = 1/6

1/6 - 1/6 = 0

-1/6a(-a+1)

you can factor out 1/6 from the equation to make -1/6a (4a-5a+1)
then combine like terms 4a-5a is -a

An inequality is solved the same way an equation is solved, with one exception. If an operation is performed that changes ordering, then the comparison symbol is reversed. The usual case is multiplication or division by a negative number:

  2 > 1
