Answer:
0
Step-by-step explanation:
You can't make 0.2 as a whole number so we can round it to the nearest whole number, 0.
Answer:
(3, -4)
Step-by-step explanation:
The correct equation is:
![y=\sqrt{x-2}-5](https://tex.z-dn.net/?f=y%3D%5Csqrt%7Bx-2%7D-5)
From the list of given points, we have to identify which point lies on the graph. This can be done by using the value of x-coordinates from the given points and see if they result in the corresponding y-coordinate:
For point (1, 4)
, This is not equal to 4, so it does not lie on the graph of given function.
For point (3, -4)
, The answer ans corresponding y-coordinate are the same. This means, (3, -4) point lies on the graph of given function.
Likewise, checking for 3rd and 4th point we find out that they do not lie on the graph.
So the correct answer is (3, -4)
Answer:
x = 7/9
Step-by-step explanation:
Answer:
We first must solve for x
![9x-x+5x=260\\13x=260\\x=30](https://tex.z-dn.net/?f=9x-x%2B5x%3D260%5C%5C13x%3D260%5C%5Cx%3D30)
When we have x, we put it in to the second equation
![Bx=200\\\\B=\frac{200}{x} \\\\B=\frac{200}{30}\\\\B=\frac{20}{3}](https://tex.z-dn.net/?f=Bx%3D200%5C%5C%5C%5CB%3D%5Cfrac%7B200%7D%7Bx%7D%20%5C%5C%5C%5CB%3D%5Cfrac%7B200%7D%7B30%7D%5C%5C%5C%5CB%3D%5Cfrac%7B20%7D%7B3%7D)
I=PRT
P=present amount
R=rate
T=time
basically
20+interest<u /> is more than or equal to 400
20+I<u>></u>400
minus 20 both sides
I<u>></u>380
solve
P=20
R=3%=0.03
T=?
I=PRT
380<u><</u>I=PRT
380<u><</u>20(0.03)(T)
380<u><</u>0.6T
divide both sides by 0.6
633.33333<u><</u>T
633.33 years at least
