So x times y=15
x+y=12
solve
x+y=12
subtract x from both sides
y=12-x
subsitute
xy=15
x(12-x)=15
distribute
12x-x^2=15
subtract (12x-x^2) from both sides
0=x^2-12x+15
use quadratic formula which is
x=

where you have
0=ax^2+bx+c
so
a=1
b=-12
c=15
subsitute
x=

x=

x=

x=

x=6+/-

x=6+

or 6-

or aprox
x=10.5826 or 1.41742
the numbers are 10.5826 and 1.41742
Answer:
Function 1 is negative with a slope of -5 and Function 2 is positive with a slope of 3.
Step-by-step explanation:
<em>Slope Formula: (y2 - y1)/(x2 - x1) </em>
<u>Function 1:</u> m = -2 - (-12) / 1 - 3
m = 10 / -2
m = 5 / -1
m = -5
<u>Function 2:</u> m = 3/1
m = 3
I might be wrong but, I would say about 32.6 miles a day. This could be wrong.
8 units right and 5 units down if your starting at the red triangle
We know that
volume of a right circular cylinder=pi*r²*h
where
r ----> is the radius
h---> is the height
in this problem
r=6 cm
h=?
Volume=550 cm³
so
V=pi*r²*h------> h=V/[pi*r²]----> h=550/[3.14*6²]----> h=4.87 cm
<span>Round to the nearest tenth
</span>h=4.9 cm
the answer is
4.9 cm
