A company that sold fish for an aquarium had a special one weekend on tetras and angel fish. The store sold a total of 110 of those types of fish over the weekend.
- The tetras each sold for $0.40 and the angel fish each sold for $1.20. They made a total of $80 in selling
those fish.
Which system of equations best represnts this situation if 1 = the number of tetras and a = the number of
angel fish
110a +0.41 = 80
a.
c.
80a +0.41 = 110
1100 + 1.21 = 80
80a + 1.21 = 110
(0.41 + 1.2a = 110
b.
d.
1+ a = 110
10.41 +1.2a = 80
1 + a = 80

its a trick question

step-by-step explanation:

dogs love water, just turn on the hose and it will run in circles chasing the water all day : )

choose (5, 1.5) and (-1.5,-3.5)

step-by-step explanation:

5 - 1.5 =3.5

-1.5 - (-3.5) = 2

3.5 + 2 =5.5

hope this !

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
