Answer:
Explanation:The simplification of that expression is done in this way:
1) The negative sign is placed in front of the whole fraction
2) 27 is divided by 3 resulting in 9: 27 / 3 = 9
3) x^2 on the numerator cancels out with x^2 of the denominator
4) z on the numerator is cancelled out with 1 z of the denominator and the result is z^5 in the denominatoir.
All that yields to :
9
- --------
z^5
Using the math editor it is:
Answer:
The equation is;
y = 1/3x
Step-by-step explanation:
The equation of a linear model is given as;
y = mx + b
m is the slope while b is the y intercept
As we can see, the y intercept is the origin and that means b is zero
To get the value of m, the slope, we have to use the slope equation
We simply select any two points on the line
We have the points as (6,2) and (15,5)
The equation of the slope is:
m = (y2-y1)/(x2-x1)
(x1,y1) = (6,2)
(x2,y2) = (15,5)
m = (5-2)/(15-6) = 3/9 = 1/3
So the equation will be;
y = 1/3x
Answer:
D
Step-by-step explanation:
to be a function you cannot have different y values for the same x, in B for example when x = 3 you have two different values for y (3,7) and (3,8)
D is the only choice where each value of x only has one value for y
