Answer:
Part 1) 
Part 2) 
Part 3) 
Part 4) 
Step-by-step explanation:
Part 1) The difference of x and 4, cubed, times 6
we know that
The difference of x and 4 is 
cubed is 
times 6 is 
therefore

Part 2) 4 less than the 3rd power of the product of 6 and X
we know that
the product of 6 and X is 
the 3rd power is 
4 less is 
therefore

Part 3) the product of x cubed and 6, minus 4
we know that
the product of x cubed and 6 is 
minus 4 
Part 4) 4 less than 6x, cubed
we know that
4 less than 6x is (
cubed is 
Answer:
(2,5)
or x=2, y=5
Step-by-step explanation:
3x+2y=16
substitute y =x+3 every place you see a y
3x + 2(x+3) = 16
distribute
3x + 2x +6 = 16
combine like terms
5x+6 = 16
subtract 6 from each side
5x+6 -6 =16-6
5x =10
divide by 5
5x/5 = 10/5
x = 2
now we need to find y
y = x+3
y = 2+3
y=5
(2,5)
or x=2, y=5
