Answer:

Both Shawn and Brielle are correct. The absolute value parent function is symmetric with respect to the y-axis, and the absolute value of negative x is a reflection across the y-axis, so the graph of these two functions would look identical. Additionally, if you wanted to verify that the given points are on the graph of both functions, you could substitute them into the functions to get true statements.

Answer:

Shawn and Brielle are correct, since absolute has the following property: |a| = |-a|, a\in \mathbb{R}

Step-by-step explanation:

Both Shawn and Brielle are correct, because the absolute value has the following property:

|a| = |-a|, a\in \mathbb{R}

Which means that |x| and |-x| gives the same result.

If A pizza restaurant offers 9 choices of vegetarian toppings for pizza In how many ways can you choose 4 toppings
Eva8 [605]
You have to pay attention in this:
- The order doesn't matter
- No repetition
- You can not chose all available elements (just 4)
So in this case your formula must be: 9C4= 9!/(4!*(9-4)!) = 126 ways

Answer:

3√11

Step-by-step explanation:

You use the Pythagorean Therom, 18^2-15^2 give you 99. You find the square root of 99, you break it down into 9 and 11. Take the square root of 9, which is three, and you cant seperate 11. So thats how you get 3√11

Write an equation for the line that passes through (0, -9) and (3, 0).
MAXImum [283]
First find the slope of the line:-

= (0- - 9) / (3 - 0)  =  9/3 = 3 

Now use the point slope form of the equation to plug in the point (3,0):-
y - y1 = 3(x - x1)
y1 = 0 and x1 = 3:-
y - 0 = 3(x - 3)

y = 3x - 9  is the answer   Its D.

Find the value of x? thank you
kirza4 [7]

Answer:

68

Step-by-step explanation:

A 5 sided shape total angles are equal to 540°

150 + 102 + 84 + x + 2x = 540

3x = 540 - 336

3x = 204

x = 68
