The common difference, d, is 5 and the starting value, a, is 2.
Filling this in the form of

Ordered pair is
<u>Step-by-step explanation:</u>
We have the following inequalities:
and
. In order to find ordered pair would be a solution on the graph .Let's solve both inequalities , and will take common solution from both of them !
and ,
which implies:
⇒
⇒
⇒ 
putting value of x in both inequalities we get,
and 
and 
and 
Hence at x =
and y =
above inequalities are satisfied. ∴ Ordered pair is
James and Monica are 15 years old and Abby is 4 years old.
A 270 degree of sector = 0.75 of its area
area = π r²
so,
0.75 π r² = 75 π
r² = (75 π)/( 0.75 π) = 100
r = +√100 = 10
so
The radius of the circle is 10 in
