x + y = 9 equation 1<span> the sum of the digits of a two-digit number is 9
</span>the number formed by interchanging the digits is 27 less than the original number<span>
we are looking at the number xy,
10x+y for x is a tens digit.
10y + x = 10x + y + 27
simplify it,
9y = 9x + 27 divide by 9
</span>x + y = 9 equation 1
y= x + 3 equation 2
by subtitution we put y in equation 1
x + (x+3) = 9
2x = 6
x= 6/2= 3
y = x+3=3+3=6
Answer:
As x→∞, y→-∞
Step-by-step explanation:
Notice how as the x values increase, the y values get closer to negative infinity. As the x values decrease into the negatives, the y values get closer to positive infinity.
The algebraic expression for the word phrase "the product of a number and 3" as a variable expression is 3z
<h3>How to write an algebraic expression for the word phrase "the product of a number and 3" as a variable expression?</h3>
The word phrase is given as:
"the product of a number and 3"
Represent the number with z
So, the word phrase can be rewritten as:
"the product of a number z and 3"
The product of a number z and 3 is represented as:
z * 3
When evaluated,, the expression becomes
z * 3 = 3z
Hence, the algebraic expression for the word phrase "the product of a number and 3" as a variable expression is 3z
