Question

Find the value of -9/5 + 8/5 ÷ 5/2 × -5/4​
plz answer in full method ​

Answer 1

Answer:

good evening friends have a great day

Step-by-step explanation:

(x + 2)² = 9

We have (something)² = 9

So, EITHER something = 3 OR something = -3

In other words, EITHER x + 2= 3 OR x + 2 = -3

If x + 2= 3. then x = 1

If x + 2= -3. then x = -5

(y + 3)² = 25

We have (something)² = 25

So, EITHER something = 5 OR something = -5

In other words, EITHER y + 3= 5 OR y + 3 = -5

If y + 3= 5, then y = 2

If y + 3= -5, then y = -8

We want to MAXIMIZE the value of x/y

If the x-value and y-value have OPPOSITE signs, x/y will be NEGATIVE

If the x-value and y-value have the SAME sign, x/y will be POSITIVE

So, need the x-value and y-value have the SAME sign

Try #1

x/y = 1/2

Try #2

x/y = (-5)/(-8) = 5/8

Since 5/8 is greater than 1/2, the correct answer is C
