Step-by-step explanation:
Lines that are tangent to a circle are perpendicular to the radius of the circle.
Lines that are tangent to a circle are congruent
When
|a|=b
assume
a=b and -a=b
so
4+|7-m|=5
minus 4 from both sides
|7-m|=1
assume
7-m=1 and
-(7-m)=1
7-m=1
minus 7 both sidees
-m=-6
times -1 both sides
m=6
-(7-m)=1
distribute
-7+m=1
add 7 to both sides
m=8
m=6 and 8
If you were to plan a party, you could use a linear equation. for example, the room you are renting is $500. The price for food per person is $10
B because pie radius square = area of a circle
