You cannot plan your thoughts if you are just thinking out loud.
Answer:
adjacent
Step-by-step explanation:
this just means they are next to each other, like they share a ray
Answer:
Not defined over the real numbers
Step-by-step explanation:
Let
This implies that:
This implies that:
The range of the cosine function is -1≤y≤1
Therefore
is not defined for over the real numbers.
Equation 1) 2x - 3y = -1
Equation 2) y = x - 1
We want both equations to be in standard form (Ax+By=C) so we need to fix the second equation.
For the second equation, simply subtract x from both sides, so that x & y are on the same side of the equal sign :)
2) -x + y = -1
1) 2x - 3y = -1
Now, we have to multiply ALL of equation 2 by 2 so that both equations 1 & 2 have "2x" in them :)
2) 2(-x + y = -1)
Simplify.
2) -2x + 2y = -2
1) 2x - 3y = -1
Now, add these equations together.
-y = -3
Divide both sides by -1.
y = 3
Now, plug in 3 for y in the first equation.
1) 2x - 3y = -1
2x - 3(3) = -1
Simplify.
2x - 9 = -1
Then, add 9 to both sides.
2x = -1 + 9
Simplify.
2x = 8
Divide both sides by 2.
x = 4
So, x = 4 & y = 3

Answer:
A. g(x) = (2x)²
Step-by-step explanation:
From the diagram of the two functions graph f(x) is the parent function and g(x) is the transformed function. you can see that the graph of g(x) is stretched vertically compared to the graph of g(x). The Parent function has y =1 corresponding to x =1 while for the transformed function when x = 1, y = 4 the graph is vertically stretched by a factor of 4, and horizontally The Parent function has y =1 corresponding to x =1. while for the transformed function when x = 0.5, y = 1, it is stretched horizontally by 2 (√4), i.e
This means that g(x) = 4x² = (2x)²
