Answer:
x = 7 , y = 7
Step-by-step explanation:
A 45- 45- 90 triangle is an isosceles right triangle with the 2 legs being congruent , that is
x = 7
Using Pythagoras' identity in the right triangle, then
y² = 7² + 7² = 49 + 49 = 98 ( take square root of both sides )
y =
=
=
×
= 7
12 ÷ 3 - 5(12) + 4(12 - 2)
= 4 - 60 + 4(10)
= -56 +40
= -16
Answer:What is the axis of symmetry and vertex for the function f(x) = 3(x - 2)2 + 4? ... Which best describes the transformation from the graph of f(x) = x2 to the graph of ... The graph of the function is 1 unit up and 2 units to the left from the graph of y = x2. ... Which statement about the function is true?
Step-by-step explanation:
The change in the stock market from the beginning of the day to the end of the day is 29 3/4
<h3>How to determine the change in the stock market from the beginning of the day to the end of the day?</h3>
The given parameters are:
Beginning = 60 3/4
End = 90 1/2
The change in the stock market from the beginning of the day to the end of the day is calculated as;
Change = End - Beginning
So, we have
Change = 90 1/2 - 60 3/4
Evaluate
Change = 29 3/4
Hence, the change in the stock market from the beginning of the day to the end of the day is 29 3/4

Answer:
Like terms are terms whose variables are the same.
We can only add them because if they does not have the same variable you do not actually know if the variables are equivalent and you will get the wrong answer.
Step-by-step explanation:
Ex: 4z,7z,108z,45z
Ex: 4w-2h+7a-2w
You can not add 4w and 7a because you do not know what the variables equal so you do not know the true number so add or subtract by.
