So basically, 9 cakes need 225 grams of flour
Therefore 1 cake needs:

= 25 grams of flour
Moreover, 20 cakes need: 20 × 25 = 500 grams of flour
500 g > 475 g
Marian does not have enough flour to make 20 cakes
1 ounce of Jarod strawberry jam is 20¢
Unit price 20¢ for 1 ounce of jarod strawberry jam
Hope this helps!

<h3>Answer : (-2,11)</h3>

<h3>Known that</h3>
y = -2x² - 8x + 3
════════════════════
<h3>Way to do + explanation</h3>
#First, find the x coordinate first by using the formula of -b/2a
x = -b/2a = -(-8)/2(-2) = 8/-4 = -2
#After getting the x, find the y
y = -2(-2)² - 8(-2) + 3
y = -2×4 +16 + 3
y = -8 + 16 + 3
y = 11
So the vertex is
(-2,11)
