This is some simple Algebra
So it's 4x+16=-2
We subtract 16 from both sides
4x=-18
Sivide both sides by 4
X=-4.5
If you need more of an explanation I am happy to elaborate
First, second, and third are the answers.
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:
∅ = 42°
Step-by-step explanation:
90 - 48 = 42° because 48 and 42 are complimentary angles (add up to 90°)
because the radii lines form an isosceles triangle, ∠∅ also = 42°
2.1 + (-3.7h) + 1.9h - 1.4
2.1 - 3.7h + 1.9h - 1.4
2.1 - 1.8h - 1.4
0.7 - 1.8h
the simplified form is 0.7 - 1.8h
