The equation x + y = z relates the whole numbers x, y, and z. How does z compare to x? If it helps, consider an example where yo
xenn [34]

Answer:

Step-by-step explanation:

Given that the equation x + y = z relates the whole numbers x, y, and z.

This implies x,y,z all three are whole numbers

Hence we get x+y =z

x = z-y

where y is a whole number

So y can be 0,1,2.....

From this we can say x can take at most the value z in case y =0 other wise x has to be less than z

So comparison of x,y,z would give

x\leq z

( the equality applying only when y =0)

uranmaximum [27]

Answer:

Step-by-step explanation:

y=ax²+bx+c

x=0,y=0,c=0

y=ax²+bx

2=9a+3b (×-5)

3=25a+5b(×3)

add

9-10=75a-45a+15b-15b

30a=-1

a=-1/(30)

2=9×(-1/30)+3b

3b=2+3/10=23/10

b=23/30

y=-1/30 x²+23/30=-1/30(x²+23x+(23/2)²)+1/30 ×(529/4)

y=-1/30(x+23/2)²+529/120
