3 0

Answer:

  12 units

Step-by-step explanation:

B - A = (7, 8) - (-5, 8) = (7 -(-5), 8 -8) = (12, 0)

The distance is then ...

  d = √(12² + 0²) = √12²

  d = 12

_____

Of course, when you graph these points (actually or mentally), you can see that they are 12 units apart on the line y=8. You don't need to do any fancy calculation to discover the difference between -5 and 7.

Subtract the polynomials then simplify: 5x^5+4x^2-2x^6+6x^4 and 10x^2+10x^3+8x^6-9x^4
Jet001 [13]

Answer:

\large\boxed{-10x^6+5x^5+15x^4-10x^3-6x^2}

Step-by-step explanation:

(5x^5+4x^2-2x^6+6x^4)-(10x^2+10x^3+8x^6-9x^4)\\\\=5x^5+4x^2-2x^6+6x^4-10x^2-10x^3-8x^6-(-9x^4)\\\\=5x^5+4x^2-2x^6+6x^4-10x^2-10x^3-8x^6+9x^4\\\\\text{combine like terms}\\\\=(-2x^6-8x^6)+5x^5+(6x^4+9x^4)-10x^3+(4x^2-10x^2)\\\\=-10x^6+5x^5+15x^4-10x^3-6x^2

Write the standard form of the quadratic equation modeled by the points shown in the table below.
Andre45 [30]
We know that

The Standard Form<span> of a </span>Quadratic Equation<span> is
</span> ax²<span> + bx + c = 0
</span>
then 
for x=0    y=-6
 a*0² + b*0 + c = -6---------> c=-6

for x=1    y=2
 a*1² + b*1 -6 = 2---------> a+b=8---------> a=8-b---------> equation 1

for x=3    y=-0
 a*3² + b*3 -6 = 0---------> 9a+3b=6---------> equation 2

<span>substituting 1 in 2
9*(8-b)+3b=6------> 72-9b+3b=6---------> 6b=66--------> b=11
a=8-11-------> a=-3
so
a=-3
b=11
c=-6
</span>Standard Form of a Quadratic Equation is
 -3x² + 11x - 6 = 0
<span>
the answer is
</span> -3x² + 11x - 6 = 0<span>

Why is it valid to say that both a function and its inverse describe the same relationship
liberstina [14]
A comparison between a function and its inverse would show that the domain and range of the original function swap. The domain of the function becomes the range of the inverse, the range of the function becomes the domain of its inverse. 

Looking at ordered pairs of the function and its inverse would look like this:

(2,4) on the original function becomes (4,2) on the inverse. 

While the graph of a function and its inverse are noticeably different an important thing to note is that it is merely a reflection across the line y=x. 

So even though they appear different you are looking at the same relationship just as y vs. x instead of x vs. y

Which set is a function?
Sonja [21]
B, short explanation remember the sets are set up like (x,y) in a set there should be no matching x points so if it matches it's not a function :)

long explanation: these are (x,y) sets {(0,3), (3,0), (0,4), (4,0)} the first choice shows that there are two X solutions <span>if they are equal to 0 (0,3) (0,4) so this cant be a function.

second choice</span><span> {(0,2), (2,0), (4,6), (6,4)} does not have two X solutions so this is a function
third choice</span>{(2,6), (3,6), (4,6), (2,0)} has two X solutions if x is equal to 2
and the last choice <span>{(6,2), (2,0), (4,6), (6,4)} has two X solutions if x is equal to 6
hope i helped! if i did please give me brainlest :)
