What is the value of x in the triangle?

[18].Simplify (TTE): x(2x+y+5) - 2(x²+xy+5) + y(x + y)

Dovator [93]

Answer:

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 5x -10 + y\²$

Step-by-step explanation:

Given

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y)$

Required

Simplify

We have:

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y)$

Open brackets

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 2x\²+xy+5x - 2x\²-2xy-10 + xy + y\²$

Collect like terms

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 2x\²- 2x\²+xy-2xy+ xy+5x -10 + y\²$

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 5x -10 + y\²$

Answer:

question 8: 30975

question 9:

I don't know if it wants me to find the interest from the bond or the quote price of the bond.

If it is the bond it would be $1400 interest.

If it is the quote price of the bond, it would be $1,239 interest.

The graph below shows the value of Edna's profits f(t), in dollars, after t months:

umka21 [38]

Since we know that the graph of our quadratic function has x-intercepts at (6,0) and (18,0), $x=6$ and $x=18$ are the zeroes of our quadratic. To find our quadratic we are going to factor each zero backwards and multiply them:
$x=6$
$x-6=0$
$x=18$
$x-18=0$

$(x-6)(x-18)=x^{2}-6x-18x+108$
$=x^{2}-24x+108$

Now that we have our quadratic function, we are going to use the average formula: $m= \frac{f(9)-f(3)}{9-3}$
$where$
$f(9)$ is the function evaluated at the 9th month
 $f(3)$ is the function evaluated at the 3rd month

$m= \frac{f(9)-f(3)}{9-3}$
$m= \frac{[9^{2}-24(9)+108]-[3^{2}-24(3)+108]}{9-3}$
$m= \frac{-27-45}{6}$
$m= \frac{-72}{6}$
$m=-12$

We can conclude that the closest approximate average rate of change for Edna's profits from the 3rd month to the 9th month is: B. −11.63 dollars per month.

The cost to ride a ferris wheel is $2.00 per person. The ferris a wheel has a capacity of

irakobra [83]

Answer:

When we have a function f(x), the domain of the function is the set of all the inputs that "work" (Not only in a mathematical way, the context is also important) with the function f(x)

In this case, we have a function M(p) = $2*p

This function represents the amount of money collected depending on the number of people who ride on the ferris whell.

Then p can be only a whole number (we can not have 1.5 people, only whole numbers of people).

And we also know that the maximum capacity of the ferris is 64 people.

Then:

p ≤ 64

And we also should add the restriction:

0 ≤ p ≤ 64

(Because p can't be smaller than zero)

Such that p should also be an integer, then, the domain is:

D: p ∈ Z, p ∈ {0, 1, 2, ..., 64}
