What's the increasing & decreasing interval of f(x)=1/2|x+7|?

Answer:

it was the butler

Step-by-step explanation:

Answer:

The answer is 48.

Step-by-step explanation:

The best way is to follow the question through. Calculate the Greatest Common Factor, in this case being 2. And the Least Common Multiple, being 60. She then subtracts the difference, in this case being 60 - 2, which gives you an answer of 48.

First, we will need to find out how much each of the bakeries accrued within 7 days. We should be able to do this by simply multiplying the amount of cakes the bakery sells each day by the amount of days it's been accruing it for.

For example:

[tex]\text{7}[/tex] • [tex]\text{7}[/tex] = [tex]\text{49}[/tex]

[tex]\text{9}[/tex] • [tex]\text{7}[/tex] = [tex]\text{63}[/tex]

Since the answer doesn't explain if you're giving EACH of the bakeries amounts or combining them, that's up to you to decide if you want to do that or not.

Answer:

f(h(-1)) = -2.5

Step-by-step explanation:

We are given:

f(x) = (x - 3)/4

h(x) = 3x - 4

Knowing this, first find h(-1).

h(-1) = 3(-1) - 4

Multiply 3 and -1.

h(-1) = -3 - 4

Subtract 4 from -3.

h(-1) = -7

Now knowing this evaluate the function out.

f(h(-1)) = f(-7)

Evaluate f(-7).

f(x) = (x - 3)/4

Substitute variable.

f(-7) = ((-7) - 3)/4

Subtract 3 from -7.

f(-7) = (-10)/4

Divide -10 by 4.

f(-7) = -2.5

This means that f(h(-1)) = -2.5.

STEP2:

Factoring: 25x2 - 4

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A² - AB + BA - B² =

A² - AB + AB - B² =

A² - B²

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 25 is the square of 5

Check : 4 is the square of 2

Check : x2 is the square of x1

Factorization is : (5x + 2) • (5x - 2)

Trying to factor as a Difference of Squares:

Factoring: x2 - 9

Check : 9 is the square of 3

Check : x2 is the square of x1

Factorization is : (x + 3) • (x - 3)

Polynomial Long Division :

Dividing : 5x + 2

By : x + 3 ("Divisor")

dividend 5x + 2

remainder - 13

Quotient : 5

Equation at the end of step2:

[tex] \frac{ (5x + 2) • (5x - 2)}{(x + 3) • (x - 3)} ÷ (5x - 2) ÷ (x + 3) \\ [/tex]

STEP3:

Divide[tex] \frac{(5x+2)•(5x-2)}{(x+3)•(x-3)} \: by \: 5x-2 \\ [/tex]

Canceling Out :

3.1 Cancel out (5x - 2) which appears on both sides of the fraction line.

Equation at the end of step3:

[tex] \frac{(5x + 2)}{(x + 3) • (x - 3)} ÷ (x + 3) \\ [/tex]

STEP4:

Divide [tex] \frac{5x+2}{(x+3)•(x-3)} \: by \: x + 3 \\ [/tex]

Multiplying Exponential Expressions:

4.1 Multiply (x + 3) by (x + 3)

The rule says : To multiply exponential expressions which have the same base, add up their exponents.

In our case, the common base is (x+3) and the exponents are :

1 , as (x+3) is the same number as (x+3)1

and 1 , as (x+3) is the same number as (x+3)1

The product is therefore, (x+3)¹ = (x+3)²

Final result :

Answer: 3rd answer is the correct answer.

Applying the Pythagorean theorem, we find that the length of the hypotenuse is equal to the square root of 2. In other words, the hypotenuse is root 2 times the length of either leg.

The number of times we would spin a number divisible by 3 is 12.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that;

Number of spins= 40

Now,

To predict how many times you would spin a number divisible by 3 in 40 spins, you can multiply the probability of spinning such a number by the number of spins. The probability of spinning a number divisible by 3 is 3/10, as there are 3 numbers out of 10 that are divisible by 3 (3, 6, and 9). the prediction is:

(3/10) x 40 = 120/10 = 12

You would expect to spin a number divisible by 3 about 12 times in 40 spins.

Therefore, by the given data the probability will be 12.

Answer:

It is 7x+21 and 7x+1 x 21

Step-by-step explanation:

The distributive property is 7x+21 and the cumulative property is 7x+1 x 21.

Given that multiplication is commutative, the distributive property can be used independently of the elements' relative positions. The Distributive Characteristics If a, b, and c are any real numbers:

Distribution favours multiplication over addition: Ab + Ac = a(b + c). A(b - c) = ab - ac shows how multiplication distributes across subtraction.

Given that Jeremy applied the distributive property to the expression 7(x+3)

Distributive property expression,

7 (x+3) = 7x + 21

Cumulative property expression,

7x + 21 = 7x + ( 7 x 3 )

Therefore, the distributive property is 7x+21 and the cumulative property is 7x+1 x 21.
