Answer:
<em>x</em><em> </em><em>=</em><em> </em><em>20</em><em>°</em>
Step-by-step explanation:
given : x + 70° = 90°
( it is shown in the figure )
- =》x + 70° = 90°
- =》x = 90°- 70°
- =》x = 20°
<em>hence</em><em>,</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>20</em><em>°</em>
Answer:
Midpoint (9,1,(8-4) = (8.5, -1.5)
step-by step:Midpoint (9,1, 8-4)=(xA+xB2,yA+yB2)=(9+82,1+−42)=(172,−32)Midpoint of a line segment (9,1, 8-4)= (8.5, -1.5)
Answer:
(6, -4)
Step-by-step explanation:
If ABCD is dilated by a factor of 2, you multiply the coordinates by 2. For the coordinate D', you would multiply 3 by 2 to get 6 and you would multiply -2 by 2 to get -4. Answer: (6, -4)
Hello there!
I'm assuming since there is no question, that you want an explanation for composite functions.
Today, I want to introduce you to a very new way of looking at functions. Think of a function as a machine. I'll call this machine f. When you plug something into this machine, it is an x-value. The machine changes the x-value into a new value which is called a y-value. This is how a function works.
With composite functions though, things get a little bit tricky. To make f(g(x)), you need to plug in x into the g machine, and it will give you an output. (y-value) The next thing you do is take that y-value and plug it into the g machine. The g machine then gives you a new value. This value is f(g(x)).
Let's do an example together...
f(x)=3x and g(x)=x²+4
if we want f(g(x)), first plug in x to the g machine. when plugging in x to the g machine, we get x²+4 as given in the question.
Now we must plug in g(x) into the f machine. Since g(x) is x²+4, we just replace x with x²+4.
We get 3(x²+4)
This means that f(g(x))=3(x²+4)
