y=8(x^2 + 4x + 4) +17 + -32
Simplify:
y = 8(x^2 + 4x + 4) + 15
Use distributive property:
y = 8x^2 + 32x +32 - 15
Simplify:
y = 8x^2 + 32x +17
Complete the square using form ax^2+bx+c:
a = 8, b = 32, c = 17
vertex form = a(x+d)^2+e
d = b/2a and e = c-b^2/4a
d = 32/2*8 = 32/16 = 2
e = 17 - 32^2/4*8 = 17-1024/32 = 17-32 = -15
Vertex form = y = 8(x+2)^2 + -15
Answer:
The amount of strawberries Lexi's sister ate=2 29/80 pounds
Step-by-step explanation:
We develop the following expressions;
Original weight of Lexi's strawberries=2 7/10 pounds
Amount eaten by Lexi's sister=fraction eaten by Lexi's sister×Original weight of Lexi's strawberries
where;
Fraction eaten by Lexi's sister=7/8
Original weight of Lexi's strawberries=2 7/10=27/10
replacing;
Amount eaten by Lexi's siser=(7/8)×(27/10)=2 29/80
The amount of strawberries Lexi's sister ate=2 29/80 pounds
33 rounds to 30 and 89 rounds to 80. 80 x 30= 2400
Reptiles and amphibians are distantly related to each other but in spite of some similarities, they can be distinguished by their physical appearance and different stages of life.
Amphibians live "double lives" — one in water with gills and the other on land by growing lungs as they age. They are vertebrates and cold-blooded (ectothermic). Early amphibians, a crucial link from fish to terrestrial reptiles, were the first animals to leave the sea and venture onto the land.
Reptiles (meaning "to creep stealthily under cover of darkness") are a group of animals that have scales (or modified scales), breathe air, and usually lay eggs. Most reptiles live on land and reproduce by laying eggs. Crocodiles, snakes,lizards, and turtles are all examples of reptiles.
Yeah, I took my guess.
