Answer:

3rd option

Step-by-step explanation:

Given z is inversely proportional to (y - 2)² then the equation relating them is

z = $\frac{k}{(y-2)^2}$ ← k is the constant of proportion

To find k use the condition when y = 5, z = 9 , then

9 = $\frac{k}{(5-2)^2}$ = $\frac{k}{3^2}$ = $\frac{k}{9}$ ( multiply both sides by 9 )

81 = k

z = $\frac{81}{(y-2)^2}$ ← equation of proportion

The football team lost 4 yards on 2 plays in a row. Which of the following could represent the change in field position?

Over [174]

Lost (⬅key word) 4 is equal to -4
On 2 plays that is times 2
So all together is -4×2
A negative times a positive is negative
-4×2= -8

Which number is not equal to one of the following expressions? 2,500 × 10 250,000 ÷ 100 2,500 ÷ 10

Answer:

2,500 ÷ 10

Step-by-step explanation:

Let's evaluate each expression one after the other and find out what they both gives us, then we'd now pick or select the one that doesn't give the required answer.

For 2,500 × 10

2500*10 = 25000

For 250,000 ÷ 10

250000/100= 25000

For 2,500 ÷ 10

2500/10= 250

So from the look of the results,

The one that gave us the odd result is

2,500 ÷ 10, and that's our answer.
