50 POINTS PLEASE HELP! Write g (x)=2f (x) as a piecewise function f (x) is defined as follows:
SEE PICTURE

Answers

Step-by-step explanation:

Since g(x) = 2f(x), we apply scalling parallel to the y-axis by a factor of 2 onto f(x).

For x + 6 if x < 2,

It becomes 2(x + 6) if x < 2.

We have 2x + 12 if x < 2.

For x² + 4x - 15 if 2 <= x <= 5,

It becomes 2(x² + 4x - 15) if 2 <= x <= 5.

We have 2x² + 8x - 30 if 2 <= x <= 5.

For 5 - x if 5 < x,

It becomes 2(5 - x) if 5 < x.

We have 10 - 2x is 5 < x.

The total age of 5 children aged 3 years is 50 years. Find the age of the youngest and oldest child?​

Answers

Given:

Consider the total age of 5 children with age difference 3 years is 50 years.

To find:

The age of the youngest and oldest child.

Solution:

Let the ages of the 5 children are x-6, x-3, x, x+3, x+6.

Sum of their ages is 50 years.

[tex](x-6)+(x-3)+x+(x+3)+(x+6)=50[/tex]

[tex]5x=50[/tex]

[tex]x=\dfrac{50}{5}[/tex]

[tex]x=10[/tex]

The age of the youngest child is

[tex]10-6=4[/tex]

The age of the oldest child is

[tex]10+6=16[/tex]

Therefore, the age of youngest child is 4 years and the age of the oldest child is 16 years.

Review: Jen sells flowers. She charges $2 per flower plug a $3 flat delivery fee. How much will she make if she has to deliver 6 flowers?

Answers

Answer:

$30

Step-by-step explanation:

Answer:

$15 dollars

Step-by-step explanation:

We know that Jen sells flowers. We also know that she charges $2 dollar per flower plus a $3 dollar delivery fee.

The question is asking how much will Jen make if she sells 6 flowers. Since every flower costs 2 dollars, we can multiply the cost and amount.

6 * 2

12.

Jen makes 12 dollars just by the flower, and now the delivery fee which is an extra 3 dollars.

12 + 3

30% times by x is 9. (x is the number we’re trying to figure out) another way to put this equation is 30/100 times x = 9. now let’s multiply both sides by 100 and divide both sides by thirty. we have x = 9 times 100/30. so the answer is 30. the puppy’s full weight is 30 pounds. hope this helps :)
