1/2 can also be written as 0.5, so you're asking what 6.5% of 580 is. To get 1% you divide by 100 which is 5.8. You can then multiply 5.8 by 6 to get 34.8 (6%). To get 0.5%, you halve 5.8 to get 2.9. Then, you add 2.9 and 34.8 which is 37.7, and that should be your answer! Hope this helped!
Only right angles measure 90 degrees.
Standard form, move the variables to the left-hand-side, leave the constant on the right-hand-side, usually the "x" comes first,
<h3>
Answer: y = (1/3)x - 2</h3>
Explanation:
The y intercept is -2 because the line crosses the y axis at this location. So b = -2
The slope is m = 1/3 because we go up 1 and over to the right 3 units. For instance, going from (0,-2) to (3,-1) follows this pattern.
You can use the slope formula for two points like (x1,y1) = (0,-2) and (x2,y2) = (3,-1) to find that m = 1/3
The slope formula is m = (y2-y1)/(x2-x1)
So that's how we go from y = mx+b to y = (1/3)x-2
ANSWER
A

EXPLANATION.
The given function is

Let

Solve for x.


Take cubic root of both sides,
![x = \sqrt[3]{ \frac{1}{2} y - \frac{21}{2} }](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%5B3%5D%7B%20%20%5Cfrac%7B1%7D%7B2%7D%20y%20-%20%20%5Cfrac%7B21%7D%7B2%7D%20%7D%20)
x is defined for all real values of y.
The range refers to the values of y, for which x is defined.
Hence the range is all real numbers.
In interval notation, we write this as,

The correct choice is A.
