Answer:
Ok, we know that we can write a horizontal translation as:
y' = f(x - A)
where if A is positive, this moves the graph of f(x) A units to the right.
Why is this?
Ok, let's compare:
y = f(x)
and
y' = f(x - A)
in y, when x = 0 we have f(0).
While to have this same point in y', we need to evaluate in x = A.
f(A - A) = f(0).
Then the value f(0) is now at x = A, this means that the point moved A units to the right.
And you can do this for all the values, so you will find that the entire graph of f(x) has ben moved A units to the right.
Based on the picture above,
The theorem or postulate that justifies that Angle HEF ~ angle HGE is :
A. AA similarity postulate
(s is used for equal side, that is used for congruent)
hope this helps
Answer:
<h3>28feet</h3>
Step-by-step explanation:
Let the wallpaper be a rectangle
Area of a rectangle = Length * Width
A = LW
Perimeter P = 2L+2W
If the wallpaper is sold in rolls that are 2 feet wide, then the width is 2 feet, to get the length, substitute W = 2 and P = 60 into the formula for calculating the perimeter of a rectangle.
60 = 2L + 2(2)
60 = 2L + 4
2L = 60-4
2L = 56
L = 56/2
L = 28
<em>The minimum length that will be purchased to cover the wall is 28 feet</em>
Answer:
Length BC = 26
Step-by-step explanation:
Perimetre = 94
; Perimetre = 2(2x + 3) + 2(3x - 1)
; 94 = 4x + 6 + 6x - 2
; 94 - 4 = 10x
; 90 = 10x
;Therefore the value of x = 9....Hence the length of BC
BC = 3(9) - 1
; BC = 26
Answer:
Trevor is just under halfway through his homework
Step-by-step explanation:
The following information is given in the question
Trevor has completed 5 of his 12 homework problems
So here the total number of homework is 12
And, out of them trevor has completed 5
So if we do the half of 12 than it would come 6
This means that trevor just under halfway the homeowrk
Therefore the last option is correct
