Answer: 2< x < 10, closed circle at 2 and 10, line inbetween them
Step-by-step explanation:
is a right triangle with base length 1 and height 8, so the area of
is
.
The average value of
over
is given by the ratio
The denominator is just the area of
, which we already know. The average value is then simplified to
In the
-plane, we can describe the region
as all points
that lie between the lines
and
(the lines which coincide with the triangle's base and hypotenuse, respectively), taking
. So, the integral is given by, and evaluates to,
Answer: 30y + 15x
If x is for sneakers, and y is for high heels, plug 15 in for a and 30 in for b. This means that x is how many sneakers she buys, and y is how many high heels she buys. The equation altogether represents the total amount of her purchases.
The correct answer is y= -18/3x
Answer:
32.99/4 is about 8.25
8.25 x 3= 24.75
about 24.75
