the translation takes the point A ( -1, -1) to (-1+4, 1) = (3, 1)
The refection in y = x 'flips' the points so (3, 1) becomes (1, 3) = A"
Do the same procedure for the other points to get the answer
(you should get B" = (-3, 3) )
The average of the given base lengths is the length of the midsegment:
... (72 + 104)/2 = 176/2 = 88
Length of the window = 9ft
The length is x feet more than the height
Therefore, the height is (9-x) ft
Percent means parts out of 100 so x%=x/100
convert to improper fraction for in x/y form so
2 and 3/8
2=16/8
2 and 3/8=16/8+3/8=19/8
convert bottom number to 100
one way is multiply whole thing by 100/100
19/8 times 100/100=1900/800
divide by 8
237.5/100=237.5%
that is precent
another way is divide completely
19/8=2.375
that is over 1 so convert to over 100 so
2.375/1 times 100/100=237.5/100=237.5%
answe ris 237.5%
Step-by-step explanation:
A function is such that every element in the domain has only 1 image in the range. The domain here are the x-values while the range is the y-values.
However a vertical line can cross the graph more than once. Hence the graph is not a function.
