Answer:
f(x) = 1.2x
Step-by-step explanation:
Given:
f(x - 5) = 1.2x - 6
Required:
Find f(x)
To solve f(x), we have to express f(x - 5) in terms of f(x).
This is done as follows
f(x - 5) = 1.2x - 6
Factorize the expression at the right hand side
f(x - 5) = 1.2(x - 5)
Now we can solve for f(x) by substituting x for x - 5 in the above expression (on the right hand side and the left hand side)
f(x) = 1.2x
Hence, if f(x - 5) = 1.2x - 6 then f(x) = 1.2x
This net is for a rectangular prism, we can find the surface area by adding all of the areas together.
the area of the small square is 2 x 2 = 4, there are 2 so 4 + 4 = 8
the area of one of the long rectangles is base x height. 20 x 2 = 40
there are 4 of these rectangles so 40 x 4 = 160
Adding it all together we get 160 + 8 = 168 ft^2
Answer:
C. tan 48° = 16.3 / x
Step-by-step explanation:
With reference angle A
Tan A = BC / AC
Tan 48° = 16.3 / x

Answer: The student is <u>not</u> correct
To reflect over the y axis, you use this rule
The x coordinate swaps in sign (from positive to negative, or vice versa) while the y coordinate stays the same.
So for a point like A(1,1), it should move to A ' (-1, 1) and not (-2,1) like the diagram shows.
B(3,1) should move to B ' (-3, 1)
C(1,4) should move to C ' (-1, 4)
It appears that the student applied a reflection over the y axis, and then they shifted the triangle 1 unit to the left.
