X^2+y^2=R^2
64+36=R^2
R=10
x^2+y^2=100
Step-by-step explanation:
c) since m = undefined => the equation is
x = -2
d) the equation is
y-2= -1/7 (x+7)
=> y = -1/7 x -1+2
<=> y = -1/7 x + 1
208 ÷ 13 = 16, so her rate is $16 per hour. Through guess and check,
Kira would have to work 11 hours to make $176.
39
sum of 2 digit no. can be
3+9
4+8
5+7
6+6 (which cannot be the ans since interchanging the digits would give 0 difference)
so,
93-39=54
84-48=36
75-57=18
so 93 is the reversed no. and 39 is the original no.
