Answer:
? = 110
Step-by-step explanation:
We know the one angle is 25 and the other is 45 because the 90 degree angle that is cut off perfectly in the middle.
All angles of a triangle always adds up to 180
Add all the known angles 25 + 45 = 70
Than subtract 180 - 70 = 110
Answer: y = 2x + 8/3
Step-by-step explanation:
6x - 3y +8 = 0
-3y + 8 = -6x
-3y = -6x - 8
y = 2x + 8/3
Answer:
∠ADB ≅ ∠CBD
Step-by-step explanation:
I did the quiz and got an hundred.
Answer:
The solution is obtained by dividing the number of flowers by the number of vases.
Step-by-step explanation:
The story problem is very straightforward. Normally, you need to read the problem and understand it.
Let's look at the question again.
Although we do not have all the quantities, we can still show how to solve the problem.
Let x be the total number of flowers.
There are 4 vases.
Therefore, the number of flowers in each vase will be:
x/4
Flow the same rule for similar problems.
To solve for the inverse of the function given;
![f(x)=x-9](https://tex.z-dn.net/?f=f%28x%29%3Dx-9)
We begin by re-writing the function as follows;
![y=x-9](https://tex.z-dn.net/?f=y%3Dx-9)
To now find the inverse, we interchange y for x, and vice versa, as shown below;
![\begin{gathered} y=x-9 \\ \text{Now becomes;} \\ x=y-9 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20y%3Dx-9%20%5C%5C%20%5Ctext%7BNow%20becomes%3B%7D%20%5C%5C%20x%3Dy-9%20%5Cend%7Bgathered%7D)
We now find the value of y;
![\begin{gathered} x=y-9 \\ \text{Add 9 to both sides;} \\ x+9=y-9+9 \\ x+9=y \\ y=x+9 \\ \text{Therefore;} \\ f^{-1}(x)=x+9 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%3Dy-9%20%5C%5C%20%5Ctext%7BAdd%209%20to%20both%20sides%3B%7D%20%5C%5C%20x%2B9%3Dy-9%2B9%20%5C%5C%20x%2B9%3Dy%20%5C%5C%20y%3Dx%2B9%20%5C%5C%20%5Ctext%7BTherefore%3B%7D%20%5C%5C%20f%5E%7B-1%7D%28x%29%3Dx%2B9%20%5Cend%7Bgathered%7D)
