2nd one, take area of whole 12 x 4=48, if area is equally divided, divide area by 2 or multiply by 1/2
Answer:

Step-by-step explanation:
The given function is f(x)=x.
If we stretch vertically by a factor of 4 and a translation of 4 units up then the new function becomes

But f(x)=x
We substitute to obtain the equation of g(x) as

Answer:
w-2u-v
Step-by-step explanation:
Given are three vectors u, v and w.
In R^2 we treat first element as x coordinate and 2nd element as y coordinate.
Thus we mark (1,2) in the I quadrant, (-3,4) in II quadrant and (5,0) on positive x axis 5 units form the origin.
b) 
We have to find the values of a and b
]
Equate the corresponding terms

Divide II equation by 2 to get

Eliminate a
-5 = 5b: b=-1
a=-2
Hence
w = 2u-v
Answer:
your answer should be $16.50 :)
Step-by-step explanation:
Answer:
43 degrees
Step-by-step explanation:
Angle B is 43 degrees, and is congruent to the vertically opposite angle by reason of vertical angles.
