Answer:
The answer is 2nd point
Step-by-step explanation:
In this question, inverse of f(x) is equals to g(x). First, you must know how to find the inverse of f(x). In order to find the g(x), you must let f(x) = y and make x thd subject :
1.
Let y = (10x+9)/8
y = (10x+9)/8
8y = 10x + 9
8y - 9 = 10x
(8y-9)/10 = x
x = (8y-9)/10
g(x) = (8x-9)/10 (Remember to convert y back to x)
2.
Let y = x - 9
y = x - 9
y + 9 = x
x = y + 9
g(x) = x + 3
Next, by looking in no.1, the inverse of f(x) is wrong and in no.2, it shows the correct form of inverse. So only 2 is an inverse function
Answer:
The dimensions are:
by 
Step-by-step explanation:
The area of the rectangle is given as
The factored form of this quadratic trinomial gives the dimensions of the rectangle.
We factor 3 first to obtain;
We split the middle term to get;
We factor within the parenthesis to get;
We factor further to get;
The dimensions are:
by
Then the perimeter will be
Answer:
The first one because if add all of the angles together they are the same.
<JKL = 180
<WXY = 180
The second one because the angles are the same.
