Hello :
<span>y = –2x² +6x – 1.
y = -2(x²-3x)-1
y= -2( x² -2(3/2)x +(3/2)² - </span>(3/2)²)-1
y = -2((x-3/2)² -9/4))-1
y = -2(x-3/2)² +7/2
the <span>axis of symmetry is the line : x = 3/2 and vertex : (3/2 , 7/2 ) </span>
The lion runs 50 miles per hour which is 20 more than a house cat. 20 mph + house cat mph = 50 → house cat mph = 30mph
Answer: 512
Step-by-step explanation: 8 x 8 x 8 = 512 (8x8=64, 64x8=512)
Hope this helps!
Mark Brainliest if you want!
The answer is B.




If you find a common denominator, the process becomes much easier. I hope this was helpful.
Since the tenths place is a greater order of magnitude than the hundredths place and .9 > .8, both 3.98 and 3.99 are greater than 3.89. Now, looking at the hundredths place, since .09 > .08, 3.99 > 3.98. Putting it all together, the numbers in decreasing magnitude are
