The answer is 11....................
For this case we have the following quadratic equation:

The solutions will be given by:

Where:

Substituting the values we have:

We have two roots:

ANswer:

Hello: <span>
<span> an equation is : y =ax+b ( a is a slope )
parallel to the line (q) : y=6/5x-1 a =6/5 ( same slope
)
the equation of (r) : is : y = 6/5x+b</span></span>
the line through point (5,5) :
5= (6/5)(5)+b ...b=-1
an equation of (r) : is : y = 6/5x-1
or : 6/5x-y = 1
Answer:
it A
Step-by-step explanation:
5+1x=3(x-7)+6
5+1x=3x-21+6
5-5+1x=3x-15-5
3x-1x=3x-3x-20
-2=-20
-20/-2=10
X=10
10%=.10
280•.10= x
28= x
280-28= DISCOUNT PRICE
252 = Discount price
