D because -50x is the amount you’re subtracting from the total
Slope = change in y / change in x
slope = (6-3) / (8-2)
Slope = 3/6
slope = 1/2
Answer:
36≤x≤48
Step-by-step explanation:
Let x represents the height of the child if a child must be at least 36 inches, this means that the child can has a height greater than or equal to 36in. This is expressed as;
x≥36
If the same child has height of no more than 48in, this can be expressed as;
x≤48
Combining both inequality
If x ≥36, this means 36≤x
Combining with x≤48 will give the compound inequality;
36≤x≤48
Factor

it simplifies to y=1
(x-7)(x-3)
they are undefined since they make the denomenator 0
solve
(x-7)(x-3)=0
x-7=0
x=7
x-3=0
x=3
restricted values are x=3 and x=7
but, the points x=3 and x=7 are holes since they were canceled out
answer is B
