Answer:
Please let me know if your quadratic is 
.
And if so your vertex is (-2,2) and your y-intercept is (0,-6)
Step-by-step explanation:
It says vertex so I'm thinking you meant . Please correct me if I'm wrong.
The vertex form of a quadratic is 
. It is called that because it tells you the vertex (h,k).
So if you compare the two forms you should see -h=2 while k=2.
-h=2 implies h=-2.
So the vertex is (h,k)=(-2,2).
To find the y-intercept, set x=0 and find y.
So the y-intercept is (0,-6).
Answer:
72 degrees
Step-by-step explanation:
180-108=72
where I got 180: a supplementary angle is 180 degrees
When given two fractions for example 2/3 divided by 3/6
the division sign changes to a multiplication sign and the fraction on the right swaps the numerator and the denominator so 3/6 becomes 6/3
so it will then be 2/3 x 6/3 and you get your answer
thats how you divide fractions
6.4 to the nearest whole number is 6
Answer:
55.2 gallons/day
Step-by-step explanation:
There are 2.4 ten-hour periods in one day, so the total number of gallons per day is ...
(2.4 periods/day)(23 gallons/period) = 55.2 gallons/day
