Please help I’m so confused

(4) f(x) = 1250(0.8)^x is the answer

Step-by-step explanation:

It can be seen that the original price you paid was $1250

After 1 year it was 1000

2 years is 800

3 years is 640

So obviously it's losing value.

But how much value?

We can find how much percentage they are losing by doing this:

1250 x 1.2 or .8 since these are you answers

1250 x 1.2 = 1500, from this we can determine that this answer is WRONG!

The value is going down, and not going up so therefore

It must be

1250 x .8 because when those are multiplied together

You get 1000!

Then 1000 x .8 = 800

800 x .8 = 640!

So we can determine that (4) Is the correct answer.

Hope this helped!

using pemdas, (order of operations) you'll see the answer is 24.

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
