Answer:
Rational
Step-by-step explanation:
An irrational number is a number with forever continuing decimals. Plug it into the calc and you can see if there is a long decimal line that ends. You should get 1.4 in the calc, and since it does end, it is a rational number.
Answer:
The answer is "
"
Step-by-step explanation:
Given value:
![\to \bold{ \sqrt[3]{x^5y} }](https://tex.z-dn.net/?f=%5Cto%20%5Cbold%7B%20%5Csqrt%5B3%5D%7Bx%5E5y%7D%20%7D)
![\to \sqrt[3]{x^5y} =(x^5y)^{\frac{1}{3}}](https://tex.z-dn.net/?f=%5Cto%20%5Csqrt%5B3%5D%7Bx%5E5y%7D%20%3D%28x%5E5y%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D)
formula:
The final value is: 
Answer:
Step-by-step explanation:
we are given a exponential equation
we want to figure out x
remember that,
thus
take 
both sides:

by using calculator
Answer:
one point
Step-by-step explanation:
A system of two linear equations will have one point in the solution set if the slopes of the lines are different.
__
When the equations are written in the same form, the ratio of x-coefficient to y-coefficient is related to the slope. It will be different if there is one solution.
- ratio for first equation: 1/1 = 1
- ratio for second equation: 1/-1 = -1
These lines have <em>different slopes</em>, so there is one solution to the system of equations.
_____
<em>Additional comment</em>
When the equations are in slope-intercept form with the y-coefficient equal to 1, the x-coefficient is the slope.
y = mx +b . . . . . slope = m
When the equations are in standard form (as in this problem), the ratio of x- to y-coefficient is the opposite of the slope.
ax +by = c . . . . . slope = -a/b
As long as the equations are in the same form, the slopes can be compared by comparing the ratios of coefficients.
__
If the slopes are the same, the lines may be either parallel (empty solution set) or coincident (infinite solution set). When the equations are in the same form with reduced coefficients, the lines will be coincident if they are the same equation.
