Answer:
If there are more than one thing on the x. Let me just show you because I can't really explain it very well, so I'm sorry.
Step-by-step explanation:
5x+23=10
23(x^2)+5=27
There is more than one thing acting on the x to get it into a number.
Answer:
x = 10 and x = -10
Step-by-step explanation:
Given the function

This function is undefied when the denominator equals to 0. Find these values for x:

This means that vertical lines x = 10 and x = -10 are vertical asymptotes (the graph of the function f(x) cannot meet these lines because this function is undefined at x = 10 and x = -10)
Answer:
The perimeter of the square is 
Step-by-step explanation:
step 1
Find the length side of the square
we know that
The area of a square is equal to

where
b is the length side of the square
we have

substitute and solve for b

square root both sides

step 2
Find the perimeter of the square
we know that
The perimeter of the square is equal to

we have

substitute


Answer:
y = -1x - 3
Step-by-step explanation:
y2 - y1 / x2 - x1
-1 - (-9) / -2 - 6
8/-8
= -1
y = -1x + b
-1 = -1(-2) + b
-1 = 2 + b
-3 = b
You know how Soh Cah Toa applies to right triangles; you can assign the adjacent side = 4 and hypotenuse = 7
CosФ = (adjacent) / (hypotenuse)
Then with the Pythagorean theorem
4² + b² = 7²
16 + b² = 49
b² = 49 - 16
b² = 33
b = √(33)
So "b" is the opposite side.
SinФ = (opposite) / (hypotenuse) = √(33)/7
TanФ = (opposite) / (adjacent) = √(33)/4
