Answer:
Y=7.5
Step-by-step explanation:
Answer:
32 percent the puppy's weighed increased.
Step-by-step explanation:
In February Lana got a puppy that weighed 13 kilograms.By October the puppy weighed 17.16 kilograms.
Original weighed = 13 kilogram
Final weighed = 17.16 kilogram.
Increase in weighed = 17.16-13 = 4.16 kilogram.
Now to find the percent the puppy's weighed increased.
Percent =
Percent =
Hence, the percent the puppy's weighed increased was 32%.
<em>Presuming you mean y = -2x^2 - 8x - 13</em>
Firstly, put the x terms in parentheses and factor out -2:
Next, we want to make what's inside those parentheses a perfect square. To do this, divide the x coefficient by 2 and square that result. In this case, that result is 4. Add 4 to the inside of the parentheses, and add 8 to the outside of the parentheses to balance it out. (Since when foiled, 4 x -2 = -8)
Next, factor what's inside the parentheses, and <u>your final answer will be </u>
Answer:
x = 299/6
y = 60 - (299/6)
Step-by-step explanation:
-5(60-x) = -1 - x
-300 + 5x = -1 - x
6x = 299
x = 299/6
y = 60 - (299/6)
