<span> we have that
standard form of equation for parabola:
(x-h)^2=-4p(y-k)
(h,k) --------->being the (x,y) coordinates of the vertex.
Parabola opens downwards because focus is below vertex on the axis of symmetry.
For given problem:
</span><span>vertex: (-3,2)
axis of symmetry: x=-3
p=distance from vertex to focus on the axis of symmetry=2-(-1)=3
4p=12
Directrix: y=2+p=5
Equation:
(x+3)^2=-12(y-2)
the answer is </span>(x+3)^2=-12(y-2)
Answer:
$33.81
Step-by-step explanation:
Strawberries = $2.49 Per Pound (Bought 3)
Blueberries = $3.19 Per Pound (Bought 2)
Pineapples = $4.99 Per Pound (Bought 4)
So we have to multiply each price with the number of fruits bought.
So, For Example, Strawberries: <em>$</em><em>2</em><em>.</em><em>4</em><em>9</em><em> </em><em>×</em><em> </em><em>3</em><em> </em><em>=</em><em> </em><em>$</em><em>7</em><em>.</em><em>4</em><em>7</em>
After you did all three individually, add them all up.
Strawberries : <em>$</em><em>7</em><em>.</em><em>4</em><em>7</em>
Blueberries : <em>$</em><em>6</em><em>.</em><em>3</em><em>8</em>
Pineapple : <em>$</em><em>1</em><em>9</em><em>.</em><em>9</em><em>6</em>
<em>Total</em><em> </em><em>=</em><em> </em><em>$</em><em>3</em><em>3</em><em>.</em><em>8</em><em>1</em>

Posting screenshot of my answer in the linked question in case it gets deleted.
Slope = (10-1)/(1+2) = 9/3 = 3
y = mx + b
1 = 3(-2) +b
1 = -6 + b
b = 7
equation
y = 3x + 7
or
3x - y = -7
answer is <span>3x − y = −7 (first choice)</span>
