If f(x)= -x+7 what is f(15)?

Answers

Answer 1

Answer: x = 15

Substitute that to equation

-(15) + 7

Answer:
f(x) = -8

Answer 2

Answer: F(x)=-x+7, and by saying “f(15)”, your saying x=15, since f(x) turns into f(15). So just replace all x’s with 15.

F(15)=-15+7
F(15)=-8

So -8 is the answer:)

London Heathrow airport see on average 191,200 passengers a day how many passengers is this per minute. I need to show the steps to my answer

Answers

First you have to ask, how many minutes are in a day?
There are 60 minutes in a hour, and 24 hours a day. You would multiply these two to find how many minutes are in a day.

24×60=1440 minutes in a day.

Now to find how many passages a minute, divide the total number of passangers, by the number of minutes.
191,200÷1440=132.7778

Even though the 7 is bigger than a 5, you do not round up because it doesn't count as a full person.
132 people a minute is your answer.

How do u do this it's something about solving proportions and I have no idea how to do this plz help

Answers

Simple...what fun!

To solve for this type of problem...it's real simple!

I will show you the easiest and fastest way to solve...

so..you have...

$(2)/(5) = (x)/(35)$

Just..CROSS MULTIPLY!!

2*35=70
and
5*x=5x

Leaving you with....

5x=70

Easy...now divide!!

$(5x)/(5) = (70)/(5)$

x=14

To check your work...plug it in....

$(2)/(5) = (14)/(35)$

simplify...

14/7=2

and

35/7=5

Thus, your answer.

In the xy plane, what is the y intercept of the graph of the equation y=2 (x+3)(x+4)?

Answers

The y-intercept is the value of y when the graph intersects the y-axis. Graphs intersect the y-axis when x=0, so we just substitute in x=0 to get:

y=2(0+3)(0+4)

y=2(3)(4)

y=24

Therefore, 24 is our answer.

Hope I helped :)
