To find the answer for this question: 

x^2 + 8x 15/x - 4xx^2 - 16/2x + 6 

Apply the exponent rule: 
x^2 + 8x + 15/x - 4x^3 - 16/2x + 6 

Divide the numbers: 16/2 = 8: 
x^2 + 8x + 15/x - 4x^3 - 8/x + 6 

Apply the rule: a/c +/- b/c = a +/- b/c 
x^2 + 8x + 15-8/x - 4x^3 + 6 

After you subtract the numbers: 15 - 8 from the fraction that equals to 7: 
x^2 + 8x + 7/x - 4x^3 + 6 

So, your answer would be: x^2 + 8x + 7/x - 4x^3 + 6.

Write an equation for your trend line?
Soloha48 [4]
Find two points on the graph that the line crosses through almost perfectly. It looks like (1,10) and (9,1) will do.

Use them to compute the slope:
m = (1 - 10) / (9 - 1)
= -9/8

Then set up the "point-slope form":
y - y0 = m * (x - x0)

You choose some point (x0, y0) that the line crosses through. We already know the line passes through (1,10) pretty well, so let's use that.

x0 = 1
y0 = 10

Now finish plugging into the equation:
y - 10 = -9/8 * (x - 1)

The above equation will work fine for an answer, but let's go a step further and solve for y.

y - 10 = -9/8x + 9/8
y = -9/8x + 9/8 + 10
y = -9/8x + 9/8 + 80/8
y = -9/8x + (9 + 80)/8
y = -9/8x + 89/8

The functions f(x)=√x^2+12x+36 and g(x)=x^3-12 are defined below. Which expression is equal to f(x) · g(x)? A.x^4-6x^3-12x+72 B.
Lostsunrise [7]

Answer:

C: x^4+6x^3-12x-72

Step-by-step explanation:

For the function : f(x)=√x^2+12x+36

It can be factorized to

f(x)=√(x+6)²

=x+6

f(x)*g(x)

=(x+6)(x^3-12)

Expand the brackets

=x^4-12x+6x^3-72

rearrange the numbers

x^4+6x^3-12x-72
