Any help on this? Y=3x+7 Y=x+1

Mathematics
1 answer:
denis23 [38]3 years ago
7 0

Answer:

The answer is (x,y)=(-3,-2)

Step-by-step explanation:

I used the comparison method because I dont know what type of method you needed, sorry. The methods I know would be: the Comparison Method (what I used), the Substitution Method, Elimination Method,Inverse Matrix Method, Cramer's Rule, and the Gauss-Jordan Method.

You can also rewrite this equation to 3x-y=-7 and x-y=-1.

I'm sorry, I dont know what kind of answer you're looking for. I really hope this helps.

Which function has a minimum and is transformed to the right and down from the parent function, f(x) = x2?
Aliun [14]

Answer:

The last choice is the one you want

Step-by-step explanation:

First of all, a parabola has a minimum value if it is a positive parabola, one that opens upward.  The first and the third parabolas are negative so they open upside down.  That leaves us with choices 2 and 4.  We find the side to side and up or down movement by finishing the completion of the square that has already been started for us.  Do this by factoring what's inside the parenthesis into a perfect square binomial.  

The second one factored becomes:

g(x)=4(x-3)^2+1

which reflects a shift to the right 3 and up 1.  Not what we are asked to find.

The fourth one factored becomes:

g(x)=8(x-3)^2-5

which reflects a shift to the right 3 and down 5.  That's what we want!
