The line is vertical. Its slope is undefined, and its equation is. X = a number.
Answer:
<h3>x = Pn</h3>
Step-by-step explanation:
Cross Multiply
The first thing you should do is to<span> divide the total cost by the unit cost you have got: </span><span>(2y^2 + 6) / (y^2 - 1) </span>
Then just use simple math by plugging in the value y=3
(2*3²+6): (3²-1)= 24:8 = 3 which is the nubmer of the bought notebooks.
<span>In total he spent $24 on notebooks that cost $8.</span>
<span>2x+12≥6
Subtract 12 from both sides
2x</span><span>≥-6
Divide 2 on both sides while flipping the inequality
Final Answer: x</span><span>≤-3</span>
