x − y = 0 = difference
x + y = 4 = sum
Can be solved by the sum and difference rule (most of the time without pen and paper)
x=(sum+difference)/2=0+4/2=2
y=(sum-difference)/2=(4-0)/2=2
8(2x+9)
= 16x+72

Answer:
2,8,32,128,512
Step-by-step explanation:
f(x)=f(x-1)*4
f(1)=2
f(2)=f(2-1)*4=f(1)*4=2*4=8
f(3)=f(3-1)*4=f(2)*4=8*4=32
f(4)=f(4-1)*4=f(3)*4=32*4=128
f(5)=f(5-1)*4=f(4)*4=128*4=512
Answer:
join the two points
Step-by-step explanation:
（x,y) = (1,3)
(just by substituting the number into the equation to make it fit)
then, also draw a point at (0.-1)
