About $5.26 will be deducted from $50
So he will get $44.74
Answer:
both should
be equal to hope my work is correct or helps
Step-by-step explanation:
first one
-25<-3x+5 subtract 5 from both sides
-25-5=-30
5-5=0
then divide by -3
-30 divided by -3 =10
x=10
so it is equal to not less than
second one
-3x+5<-31
subtract 5 from both sides 5-5=0
-31 -5=-36
then divide both sides by -3
x=12

The center is at origin O(0,0).
If it contains the point, P(-8,6), then the radius r is, by Pythagoras theorem,
r=sqrt((-8)^2+6^2)=10
The general equation of a circle at centre (xc,yc) with radius r is given by
(x-xc)^2+(y-yc)^2=r^2
Substituting r=10, (xc,yc)=(0,0)
the resulting equation is therefore
(x-0)^2+(y-0)^2=10^2
or simply
x^2+y^2=100
