If we were to subsitute the points and graph the equation we would notice that the shape is the same for both: a 45 degree angle line that goes upleft and up right
the graph of y=|x| looks like a right angle corner that is facing up that is ballancing on the point (0,0)
the graph of y=|x|-4 is the same except that the graph is shifter 4 units to the right ie. the point ofo the graph/rightangle is on point (4,0)
Answer:
So 4th choice seems more accurate than others.
Step-by-step explanation:
Given function is
compare this formula with f(x)=a|x-h|+k, we get h=-4, k=-6
We know that vertex for above formula is given by (h,k) then vertex for given function will be (-4,-6)
which is different than given choice so first choice is not possible.
We see that 2/3 is multiplied outside of the parent function |x| so that will create vertical not horizontal compress so 2nd choice is wrong.
when value of a is positive the graph opens up. But we have a=-2/3 which is negative so graph will open down. Hence 3rd choice is wrong.
Absolute function will have domain, all real number so x<=-6 is part of that which is partially correct.
So 4th choice seems more accurate than others.
Answer:
15=24
20=x
cross multiply
15x=24*20
15x=480
divide both sides by 15
x=480/15
x=32
it will take her 32 minutes
