Hello :
<span>y = -2x² + 8x - 5 = -2(x²-4x-5)
but : </span>x²-4x = (x²-4x +2²)-2²
= (x-2)² -4
y = -2 ((x-2)²-9)
y = -2 (x-2)²+18
the vertex is A(2,18)
Answer:
Yes they are simular but what is SAS and AAA?
Step-by-step explanation:
1,578 pillows. For this I just multiplied 789 by 2 and that’s the problem I got. I also double checked it by dividing 1,578 by 2 and this I got 789
Answer:
C
Step-by-step explanation:
2 (20)=40
70-40=30
30/2 = 15 actual width of both sides
P= 2l + 2w
Answer:
(If you need the actual explanations for each one, just ask in comments)
Step-by-step explanation:
1: D
2: G
3: A (60/100 = 6/10 = 3/5)
4: H (Min = 18, Q1 = 19, Median = 23, Q3 = 24, Max = 26)
5: C (2:6 = 1:3; 3:9 = 1:3)
6: J (2:15 = 10:75; multiply each side by 5)
7: A (A & B: 6*2/3 = 4, 4 < 6, 4 not > 6. C: 6*3/2 = 9, 9 not < 6. D: 6*3/3 = 6 not > 6).
