Answer:
1.1 ithink
Step-by-step explanation:
SOLUTION
Write out the equation

To solve this system of equation, the aprropriate method will be substitution
Substitute the expression for y into the second equation for y, we have

Expand the paranthesis we have

Divide both sides by 4, we have

Since the value of x has been obtained, we substitute into the first equation

Therefore
x = -3, y= -4
Answer:
Step-by-step explanation:
I don’t know if this will help but I hope it does let me know if you get it or not
Standard form is ax^2+bx+c=0
First evaluate the exponent and expand (foil).
y= 3(x^2-4x+4)+1
Then distribute the 3
y= 3x^2-12x+12+1
Combine like terms
y=3x^2-12x+13
Final answer: 3x^2-12x+13=0
