Jose and Caroline went shopping for school supplies. Caroline spent $15.50 on
5 notebooks and 3 folders. Jose bought
4 notebooks and 4 folders and spent $14.
Write a system of equations to represent
this situation. Then solve the system of
equations by substitution. Explain what the
solution means.

i understand 100% 10/10 hit or miss?

step-by-step explanation:

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
