consider the function f(x) = x2 2x – 15. what are the x-intercepts of the function? left-most x-intercept: ( , 0) right-most x-i
eimsori [14]

we have

f(x)=x^{2} +2x-15

we know that

The x-intercept is the value of x when the value of the function is equal to zero

so

in this problem

Find the roots of the function

equate the function to zero

x^{2} +2x-15=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

x^{2} +2x=15

Complete the square. Remember to balance the equation by adding the same constants to each side

x^{2} +2x+1=15+1

x^{2} +2x+1=16

Rewrite as perfect squares

(x+1)^{2}=16

Square root both sides

(x+1)=(+/-)\sqrt{16}

(x+1)=(+/-)4

x=-1(+/-)4

x1=-1+4=3

x2=-1-4=-5

x^{2} +2x-15=(x-3)(x+5)

therefore

<u>the answer is</u>

the x-intercepts are the points (3,0) and (-5,0)

3. A city planner is measuring the distance of one city block. Which unit of measure should she use: 1 mile, 1 meter, 1/2 inch?
yawa3891 [41]
You should use the 1 mile because the meter and inch is too short to measure the city block and it’ll take really long this is why you should use 1 mile.

so uh i have a question about STEAM the app ik this is a math website but uh my question is lets say your playing roblox or mine
yawa3891 [41]

Answer:

Step-by-step explanation:

First off, steam isn't a math website.

On discord, it doesn't show steam specifically, but if you're playing a game THROUGH steam then yes, it will show.

To hide this, go to options -> game activity -> and disable "Display currently running game as a status message" on discord.

If you want to hide your status on steam, just put your status to invisible :)

How to set up a problem for law of sines when m
Sergeu [11.5K]
I think you meant to have more of a problem stated.
Basically, you use the Law of Sines when you have 2 angles but the length of only one side.

The formula for this law is
a / sine(A) = b / sine(B) = c / sine(C)
