The answer is 50/27 or 1 23/27 or approx 1.85185. Here is my work!
Multiply both sides by 10 : 20x + 6x = 50 - x
Collect the like terms: 20x + 6x = 50 - x
Move Variable to Left: 26x + x = 50
Collect like terms: 27x = 50
Divide both sides by 27: 50/27
Hope this helped :))
Domain is the collection of the x values: {14, 5, -1, 9}
So basically what you would is u would plug the first equation into the second equation. -5x+21=4x+6
-21 -21
-5x=4x-15
-4x -4x
-9x=-15
-9x/-9=15/-9
x=-1.66
then you would plug x back into the equation to get your y value
y=4(-1.66)+6
y=6.64+6
y=12.64
Answer: First, Third and Fourth options are correct.
Step-by-step explanation:
As we know that Rational numbers are those numbers which can be positive integers, negative integers and can be written in the form of p/q i.e. in fractions.
So, it is true for positive integers
It is true for negative integers.
It is true for fractions.
Hence, First, Third and Fourth options are correct.
