Answer:

See below (along with attached graph)

5th point can be of personal choice

Step-by-step explanation:

<u>X-intercepts/Roots</u>

y=-x^2-2x+3\\\\0=-x^2-2x+3\\\\0=-(x^2+2x-3)\\\\0=-(x+3)(x-1)\\\\x=-3,\: x=1\\\\(-3,0)\:and\:(1,0)

<u>Y-intercept</u>

y=-x^2-2x+3\\\\y=-(0)^2-2(0)+3\\\\y=3\\\\(0,3)

<u>Vertex</u>

x=-\frac{b}{2a}\\ \\x=-\frac{(-2)}{2(-1)}\\ \\x=\frac{2}{-2}\\ \\x=-1\\\\y=-x^2-2x+3\\\\y=-(-1)^2-2(-1)+3\\\\y=-1+2+3\\\\y=4\\\\(-1,4)

Zanzabum
Call w the unknwon price of the walnuts, then:

total cost of walnuts = 1oz *  w

Total cost of peanuts = 4 oz * $4/oz = $16

Total cost of nuts = 5oz * $5 /oz = $25

=> 1oz*w + $16 = $25 => w = ($25 - $16) /1oz = $9/oz

Verfify:

1oz * $9/oz + 4oz * $4/oz = $9 + $16 = $25, which is equal to 5oz * $5/oz.
