The correct answer is (10,-20), because the equation already gives you the correct x value. Then, from there you just plug 10 in for x in the y equation. Giving you a -20, :)
Answer:
Step-by-step explanation :4.0148 rounded to the nearest thousand is 0, but if you meant rounded to the nearest thousandth, it would be 4.015 because the 8 in the ten thousandth column would cause the 4 in the thousandth column to round up to 5.
Answer:
It'd be a rational number
Step-by-step explanation:
<em>Real numbers are a set of numbers containing all of the rational numbers and all of the irrational numbers. </em>
Types of numbers <u>in the rational number "section" are decimals, whole, mixed, and fraction numbers whether they are negative or positive they are rational numbers.</u>
Irrational numbers are numbers that cannot be expressed as the ratio of two integers. So they would be square root, pi and more.

6x^2-7x-3=0
Solve by completing the square:
x^2-7/6x-1/2=0 (divided everything by 6)
