Answer:
Step-by-step explanation:
You would never buy a 10-pack, because two 5-packs cost less.
To buy 3 bars you need a single bar and a pair of single bars for £0.82 + £0.82+ £0.41 = £2.05
To buy 30 bars you need 3 pairs of 5-bar packs = 3×£5.75 = £17.25
To buy the remaining 5 bars you need one 5-bar pack = £3
cost = £2.05 + £17.25 + £3 = £22.30
Answer:
Already in standard form
Step-by-step explanation:
A quadratic equations standard form is ax^2 + bx + c. This equation is already in standard form.
ax^2 + bx + c
1/2 x^2 - 4x + 3
1. -1/3 - (-1/2) = .16666666666666
2. -8
Hope it helps, if you need it in fractions, you can always convert it :)
8x=24 which is 3 so x = 3
4y=24 which is 6 so y = 6
(3,0) for x and (0,6) for y
