Interest=percent times rate(in years) times principal.
Or I=PRT
So you invest $580 so I=$580 Rate would be .10 and time would be 1 for one year. So if you put this into the formula you get
$580=P(.65)(1)
So $580=.65P so $580/.65=P so P is approximately $892.31 per year.
Answer: -(x-6) (x+2)
Step-by-step explanation: screenshot
Answer:
Since
x
=
6
is a vertical line, there is no y-intercept and the slope is undefined.
Slope: Undefined
y-intercept: No y-intercept
In the HL theorem, the hypotenuse and one length of the two triangles are equivalent. In order to calculate the value of x, we equate the two values of the hypotenuse:
2x + 9 = 4x - 1
2x = 10
x = 5
With x = 5, the hypotenuse of SUV works out to be 19, and the hypotenuse of WUT also works out to be 19.
Answer:
It's irrelevant.
Step-by-step explanation:
20 theater tickets cost 20T, 16 cinema tickets cost 16C.
Their sum is 20T+16C
You can factor a 4 out of this expression to get 4(5T+4C).
The two expressions are completely equivalent: there is no reason, in general, to prefer 20T+16C or 4(5T+4C).
Sometimes, the exercise may ask explicitly for the factored form.
In other cases, one of the two expression might be more useful: if you had to divide everything by 2, of course it's easier to write
![\dfrac{4(5T+4C)}{2} = 2(5T+4C)](https://tex.z-dn.net/?f=%5Cdfrac%7B4%285T%2B4C%29%7D%7B2%7D%20%3D%202%285T%2B4C%29)
If instead you had to subtract 10T, it would be more useful to write
![20T+16C-10T = 10T+16C](https://tex.z-dn.net/?f=20T%2B16C-10T%20%3D%2010T%2B16C)
To recap, 20T+16C and 4(5T+4C) are completely equivalent, and unless you have explicit requests, you may prefer one or the other depending on the calculations you have to do.
