Answer:
➳ These equations will have <u>infinite solutions</u> because they are in 2 variables. Any value can be substituted in the place of the variables x & y.
Answer: The difference is factor is a circumstance, fact, or influence that contributes to a result or outcome. and multiple is A multiple of a number is that number multiplied by an integer.
Step-by-step explanation:
72% can also be written as 0.72, so take 0.72 x 45 = 32.4
Subtract 32.4 from 45 45 - 32.4 = 12.6 You need 12.6 renewals in 5 days.
Answer:
units
Step-by-step explanation:
The distance formula is 
where 
is the distance between points 
and 
. Let 
and 
, thus:
Therefore, the distance between points P(5,1) and Q(3,4) is units.
We know that
the equation of the parabola is of the form
y=ax²+bx+c
in this problem
y=1/4x²−x+3
where
a=1/4
b=-1
c=3
the coordinates of the focus are
(-b/2a,(1-D)/4a)
where D is the discriminant b²-4ac
D=(-1)²-4*(1/4)*3-----> D=1-3---> D=-2
therefore
x coordinate of the focus
-b/2a----> 1/[2*(-1/4)]----> 2
y coordinate of the focus
(1-D)/4a------> (1+2)/(4/4)---> 3
the coordinates of the focus are (2,3)
