Select the equation of the line that passes through the .5,7 and is perpendicular to the line x equals 4

1 answer:

8 0

Hello!

To be perpendicular to x = 4, the line must be y = something. This eliminates answer choices #2 and #4. Also, to pass through the point (.5, 7), the line must be y = 7.

So answer choice #3.

Hope this helps!! Let me know if you have ANY questions.

The population of a small town is decreasing exponentially at a rate of 14.3% each year. The current population is 9,400 people.

Answer:

After 2.9 years the town's tax status will change

The towns tax status change within the next 3 years

Step-by-step explanation:

The question below is

Will the towns tax status change within the next 3 years ?

Let

y -----> the population of a small town

t ----> the number of years

we have a exponential function of the form

$y=a(b)^{t}$

where

a is the initial value

b is the base

In this problem

$a=9,400\ people$

$b=100\%-14.3\%=85.7\%=85.7/100=0.857$

substitute

$y=9,400(0.857)^{t}$

Remember that

The town's tax status will change once the population is below 6,000 people

The inequality that represent this situation is

$9,400(0.857)^{t}< 6,000$

Solve for t

$(0.857)^{t}< 6,000/9,400$

Apply log both sides

$(t)log(0.857)< log(6,000/9,400)$

$-0.067t< -0.1950$

Multiply by -1 both sides

$0.067t > 0.1950$

$t > 2.9\ years$

After 2.9 years the town's tax status will change

therefore

The answer is

Yes, the towns tax status change within the next 3 years

How do you find the X and Y values and what theorems must I use?

KIM [24]

Well you find them with the knowledge that all the angles on any of the given point add up to 360 degrees. Also that angles that are opposite from each other are the same.

Helppppppppp??? Pls !!!

Answer:

a. 19

Step-by-step explanation:

5/6x-1/5x=19

5/6(30)-1/5(30)=19

25-6=19

19=19

?/30(30)=19

19/30(30)=19

19=19

I'm not sure if this is exactly what you're looking for, but 19=19 if you plug in 19 for the box (and x=30 because of the first section, I'm guessing)

Which of the following is equivalent to the expression below?

larisa [96]

Answer:

4a^2-6b^2+12

Step-by-step explanation:

(a^2 - 2b^2 + 3) - (4b^2 - 5) + (3a^2 + 4)

distribute the negative sign to each term in the 2nd expression

a^2-2b^2+3-4b^2+5+3a^2+4

combine like terms

4a^2-6b^2+12
