Page from ready workbook, it’s about rational numbers
The range is the difference between the LOWEST value and the HIGHEST value.
The range is the set of POSSIBLE output values, and that is shown on the Y-AXIS!!
D1 = 60 for a price of $80. Charging $80 will ensure supply exceeds demand.
___
The store apparently could charge a price slightly lower than $80, but we cannot tell from the chart how much lower.
Answer:
y < 1.1
Step-by-step explanation:
<u>Step 1: Subtract 2.1 from both sides
</u>
-4.2y + 2.1 - 2.1 > -2.52 - 2.1
<em>-4.2y > -4.62</em>
<em />
<u>Step 2: Divide both sides by -4.2</u>
-4.2y / -4.2 > -4.62 / -4.2
<u><em>Since you divided by a negative, that flips the sign.</em></u>
<em>y < 1.1
</em>
Answer: y < 1.1
<7 and <10 are each 84 degrees
