Answer:

The answer would be 2.7. Am not very sure though

Step-by-step explanation:

So what you do is

for example the unkown number is x and the answer you get is y

12-x=y * -15=-140

-140/-15=9.33 (this is y the answer)

12-x=9.3

12-9.3=2.7

To check your answer

12-2.7=9.3

9.3 * -15=-139.5 if you round it then it would be -140

ANSWER PLEASEEE. Jackie, a nurse at an emergency care facility, is operating on a patient with Dr.
TiliK225 [7]

Answer:

This is math????

Step-by-step explanation:

A, because this shows that jackie is just making sure that the doctor didn't forget anything in a not rude way. The other ways she is kinda asserting her thoughts as Right and  the doctor is wrong, or she assumes he knows what he is doing when he might have actually forgotten.

The rule that maps each domain value to its range value is f(x)= ___x.
kirill115 [55]

Answer:

f(x) = 1/2x

Step-by-step explanation:

When x = -4  the output is -2

We are dividing by 2

When x = -2 the output is -1

f(x) = 1/2 x

Check when x = 2

f(2) = 1/2 (2) =1
