how do you know of an exponential fuction is reflected across the x-axis?

Answers

Answer:

Step-by-step explanation:

A reflection over the x-axis changes all the y-values. The reflection is modeled as -f(x)

For example:

[tex]\sqrt{x}[/tex] would look like --[tex]\sqrt{x}[/tex] .

If the negative sign is outside of the bracket ( what it's called sorry), then it is a reflection over the x-axis

However if the negative sign was inside the bracket: [tex]\sqrt{-x}[/tex] then this would be a reflection over the y axis.

The ratio of dogs to cats in the neighborhood was 3 to 7. If a total of 210 dogs and cats were in the neighborhood, how many cats were there? Complete the statement by providing the correct response in number form.

Answers

Answer:

147 cats

Step-by-step explanation

There are 3 dogs/ 7 cats

3x + 7x = 210

10x = 210

210 ÷ 10 = 21

Therefore,

x = 21.

dogs would be 3x (3 x 21) = 63

cats would be 7x (7 x 21) = 147

Let a and b be rational numbers.

Find the missing height of the parallelogram described. b = (x + 4) yd, (blank text) yd, (5x + 20) yd2

Answers

Answer:

5yards

Step-by-step explanation:

Area of the parallelogram = Base * Height

Given

Area = (5x+20)yd²

Base = (x+4)yd

Required

height

Substitute into the formula

5x+20 = x+4 * Height

Height = 5x+20/x+4

Height = 5(x+4)/x+4

X+4 cancels out to have;

Height = 5

Hence the height of the parallelogram is 5yards

Milo drinks 2/5 of a bowls of water in 1/3 of an hour. How many hours will it take Milo to drink an entire bowl of water?

Answers

Answer:

It would take Milo 5/6 of an hour to drink an entire bowl of water.

Step-by-step explanation:

In this case, you can use a rule of three to find how many hours it will take to drink 1 bowl of water given that 2/5 of a bowl of water takes 1/3 of an hour:

2/5 of a bowl → 1/3 of an hour

1 bowl → x

x=(1*1/3)÷2/5

x=1/3÷2/5

x=(1*5)/(3*2)

x=5/6

According to this, the answer is that it would take Milo 5/6 of an hour to drink an entire bowl of water.
