If xy=0 assume that at leas 1 is zero
set it to zero
0=2a^2-16a+32
undistribute 2
0=2(a^2-8a+16)
2*0=0 so assume
a^2-8a+16=0
factor
(a-4)(a-4)=0
set to zero
a-4=0
a=4
when a=4, equation equals zero
Answer:
Step-by-step explanation:
(a) Option B cost less at 120 miles driven
The cost difference at 120 miles between option A and option B is $15
(b) Option A and B cost the same at driving 60 miles.
Option B would cost more if you drive less than 60 miles.
x+15 less or equal to 60: x is the extra you can spend
Answer:
The solution is the table 1 (see the attached figure)
Step-by-step explanation:
we know tat
Table 1
In the interval (-2.-1) -----> increase
In the interval (-1.1) -----> decrease
In the interval (1,2) -----> increase
Table 2
In the interval (-2.2) -----> decrease
Table 3
In the interval (-2.-1) -----> decrease
In the interval (-1.1) -----> increase
In the interval (1,2) -----> decrease
Table 4
In the interval (-2.2) -----> increase
therefore
The solution is the Table 1
