Answer: For a given quadratic y = ax2 + bx + c, the vertex (h, k)
Step-by-step explanation:
Answer:
10h + 10 - 4 = 76;
10h + 6 = 76;
10h = 76 - 6;
10h = 70;
h = 70 ÷ 10;
h = 7;
Check: 10 · ( 7 + 1 ) - 4 =
10 · 8 - 4 =
80 - 4 =
76 TRUE
Step-by-step explanation:
Using the first line 8 servings / 2 liters = 4 servings per liter.
Finishing the table:
4 liters x 4 = 16 servings
20 servings / 4 = 5 liters
7 liters x 4 = 28 servings
Hello from MrBillDoesMath!
Answer:
w = 5
Discussion:
48 = 2 (2w) + (4 + 2w)2 =>
48 = 4w + 4*2 + (2w)*2 =>
48 = 4w + 8 + 4w => as 4w + 4w = 8w
48 = 8w + 8 => subtracting 8 from each side
48 - 8 = 8w => divide both sides by 8
(48 -8 )/8 = w =>
40/8 = w =>
w = 5 =>
Check: 2(10) + ( 4 + 2*5)*2 = 20 + 14*2 = 20 + 28 = 48
Thank you,
MrB
