Step-by-step explanation:
< open circle, not ≤
Given:
limit of $36 and 20 pounds of food in his back pack
pasta : 1 pound package @ $1
pasta sauce: 1.5 pound jar @ $3
x = number of pasta package
y = number of jar of pasta sauce
Constraint on the weight:
x + 1.5y <u><</u> 20
Constraint on the cost of purchase.
x + 3y <u><</u> 36
Answer:
Option B is correct.
Step-by-step explanation:
Give equation of circle,
x² + ( y + 5 )² = 25
x² + ( y + 5 )² = 5²
Standard equation of circle is given by,
( x - h )² + ( y - k )² = r²
here ( h , k ) are the coordinates of the center of the circle.
r is the radius of the circle.
By comparing with standard equation,
we get
( 0 , -5 ) is coordinate of the center of the circle.
and radius of the circle is 5 unit.
Only graph B has ( 0 , -5 ) center.
Therefore, Option B is correct.
