23
Steps ig
((8x2) +2x(-3)))-(((-(-4)) x 2) +( 3 x( -7)) =23
Answer: 
Step-by-step explanation:
x^2+y^2=r^2 --> subtract x^2 to other side
y^2=r^2-x^2 --> square root both sides
y=sqrt(r^2-x^2)
Answer:
x= -8
Step-by-step explanation:
x/2 is greater than of equal to -4
hence
x/2=-4
x=-4*2= -8
Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x ---> represents the number of matinee tickets she could purchase
y ---> represents the number of evening tickets she could purchase
we know that
The number of matinee tickets (x) multiplied by $7.50 each plus the number of evening tickets (y) multiplied by $12.50 each must be at most (less than or equal to) $100
so
The inequality that represent this problem is

using a graphing tool
The solution is the triangular shaded area
Remember that the number of tickets must be a whole number
see the attached figure
