Hi, Elanham3. What you're lookin at here is a quadratic equation. Now, they're actually pretty easy to solve, if you know how to. A quadratic equation can a lot of the time be expressed as 2 binomials. From looking at the first part, x^2, we can see the first part of each binomial-x. Also, all of the symbols in the quadratic equation are positive, so we know that they are also positive in the simplified form. So, the 2 binomials are (x+ )(x+ ). Then, we need to find the 2 factors of 48 that add together to get 26. So-

1*48 No

2*24 Maybe...

2+24=26- That's it!

Now that we know this, we know both of the binonials. The full equation is now

(x+24)(x+2)=0

Check it-

x^2+24x+2x+48

x^2+26x+48- That's right.

Now, the original equation was equal to zero, so we set both equal to zero, because if x= either of those, because anything X zero= Zero.

(x+24)=0 (x+2)=0

x=-24 and x=-2

Those are your solutions.

Hope it helps!

borishaifa [10]

Answer: $x+y\geq 1$ , $x>\frac{1}{4}$ , $x\geq 2y$ and $y\geq 0$

Step-by-step explanation:

Here, x represents the number of hours Zoe spent running on her wheel and y represents the number of hours spent scratching her cage.

Julie was awoke for at least an hour running on her exercise wheel and scratching the of her cage.

⇒ $x+y\geq 1$

She ran on her wheel at least twice as long as she scratched at the corners of her cage.

⇒ $x\geq 2y$

Also, She spent more than 1/4 hour running on her wheel.

⇒ $x>\frac{1}{4}$

And, we know that number of hours can not be negative.

⇒ $y\geq 0$

Therefore, the complete system of inequality which shows the given situation is,

$x+y\geq 1$ , $x>\frac{1}{4}$ and $x\geq 2y$ , $y\geq 0$

Note: the feasible region ( covered by the given system) is shown in the below graph.

Rewrite each expression in the form kkxxnn, where kk is a real number and nn is an integer. Assume x ≠ 0.

labwork [276]

Answer:

The expression will be $2x^5\times x^{10}=2x^{5+10}=2x^{15}$

Step-by-step explanation:

We have given the expression $2x^5\times x^{10}$

We have to write this expression in kkxxnn form , here kk is real number and nn is integer

We know the property of exponent that when two function are multiplied thn their exponent are added

So $2x^5\times x^{10}=2x^{5+10}=2x^{15}$

Here kk = 2 and nn = 15
