Answer:
The first one: the error was that the 3 shouldn’t have been moved but the 5 should have. The correct answer is k=-8
The second one: the error was that they added the 6 and 4, you would only get -10 if the 4 was - the correct answer is -2
You can check your answer by plugging in your answer to the variable and making sure both side equal each other
Step-by-step explanation:
The first one: the 5 should be - from both side so you get k=-8
The second one: the 4 should be + to both sides. And the -6 and +4 should be added together to get n=-2
Remember you always want to get the variables by themselves.
Sorry that was a lot. Hope it helps!
The vertex form needed is :
Given the equation:
The vertex form of 
is given by:
Here, (h,k) is the vertex of the parabola equation given.
Conversion will go like this:
This is the resultant vertex form.
Thus the vertex form needed is :

Answer:
f(x)=x-2
Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Domain: (−∞,∞),x|x ∈R}(-∞,∞),{x|x ∈R}
Range: (−∞,∞),{y|y∈R}
g(x)=x^2-3x+2
Domain: (−∞,∞),{x|x ∈R}(-∞,∞),{x|x ∈R}
Range: [−1/4,∞),{y∣y≥−1/4}
Answer:
x= 3/5
Step-by-step explanation:
SOH-CAH-TOA
You have the adjacent and hypotenuse so you will use Cosine
cos=adj/hyp
adj=3
hyp=5
3/5 = cos (or theta)
