Answer:

x = 4

Step-by-step explanation:

f(x) = I  x+1 I ​

when x = -5

f(-5) = I  (-5) +1 I

= I  -5+1 I ​

= |-4|

= 4

Answer:

substitute x for -5

f(-5)=|-5+1|

f(-5)=|-4|

however, absolute value is the distance from 0 and so is always positive since you cannot have negative distance.

so f(-5)=4

First put a bubble around 5x-7. Now you plug that into the problem. -3x-2
(5x-7)=12. now times the -2 by 5x which is -10x. and then times the -2 by -7 which is 14. so now you have -3x-10x+14=-12. add the -3x and -10x. -13x. Add the 14 over. -13x=2. Now dived by -13, which gives us x=-0.15

Now you take that a plug it into the -3x-2y=-12. So that it looks like this -3(-0.15)-2y=-12

Now times the -3 by -0.15 to give us 20 -2y=-12.   Now 'kill' the 20, so that it looks like this -2y=-32. Now you divide by -2 and get y=16. 

Now your ordered pair is (-0.15,16)

Total problems = 24

she completed the first 12 problems in 1 hour

The last 12 in 3 hours.

Total time = 1 hour + 3 hours
