Answer:
x = -6
-18+4y=0 => 4y=18 =>y=18/4=9/2
Y=5
3x+20=0 => x=3x= -20=> x= -20/3
Step-by-step explanation:
Making a table helps compare two or more sets of data because you can look at how much it has increased or decreased.
Answer:
C & D
Step-by-step explanation:
x² + 3x - 3 = 0
a = co efficient of x² = 1
b= co efficient of x = 3
c = constant = -3
roots = (-b ±
)/2a
= (-3±
)/2*1
= (-3±
)/2
= (-3±√21)/2

The answer would be C) 2x + 10.
Expand ( -3x + 5x + 10 )
Simplify ( 2x + 10 ).
Answer:
D
Step-by-step explanation:
Area of H = 25pi
Area of J = 225pi
225pi/25pi = 9
