On what interval is the function h(x) = |x − 5| + 2 increasing?

Step-by-step explanation:

This is an absolute value function, and since it is positive, it will decrease to its point as it comes in from the left and then increase from its point as it goes on to the right.  The vertex of this function sits at (5, 2).  This means that the function is increasing from an x value of 5 all the way up to infinity.

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
