Step-by-step explanation:
Answer: a = 3.5
Step-by-step explanation:
14=4a
divide both sides by 4
14/4 = 3.5
4a/4 =1a or a
so a= 3.5
Answer:
The last two functions are decreasing!
Step-by-step explanation:
You can easily tell the functions are decreasing if the function is going down from L to R. If it is going up, from L to R, then it is increasing!
Answer:
D!
Step-by-step explanation:
a and b - we cant do translations, because the shapes size would be preserved
so its between c and d
c makes it smaller - so even smaller than KLM
d makes KLM larger(into K'L'M'), and since it is the last option, D is correct

Answer:
the translation is 4 units at right and 2 units up
Step-by-step explanation:
see the attached figure to better understand the problem
looking at the graph
we have
The coordinates of the pre-image ABC are
A(-1,1),B(2,2),C(1,-1)
The coordinates of the image A'B'C' are
A'(3,3),B'(6,4),C'(5,1)
so
A(-1,1) ----> A'(3,3)
A(-1,1) ----> A'(-1+a,1+b)
-1+a=3 ---> a=3+1=4
1+b=3 ---> b=3-1=2
The rule of the translation is
(x,y) ----> (x+4,y+2)
That means ----> the translation is 4 units at right and 2 units up
