The estimated solution is (0,0 ).
The algebraic solution is (
Step-by-step explanation:
We need to solve the system of equations:
Solving using Elimination method
Let: 
Multiply eq(1) by 4 and add eq(1) and eq(2)
So, value of x is 
Converting into whole number: x=0
Now finding value of y
Putting value of x into eq(1)
So, value of y is 
Converting into whole number: y=0
The estimated solution is (0,0 ).
The algebraic solution is (

Answer: La ecuación de la recta que pasa por los puntos (-3, 2) y (-5, 8) es 3x + y + 7 = 0.
Answer:
The vertex is the point (-1,11). is a maximum
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to
where
(h,k) is the vertex
a is a coefficient
if a > 0 the parabola open upward and the vertex is a minimum
if a < 0 the parabola open downward and the vertex is a maximum
we have
Convert to vertex form
Complete the square
Factor the leading coefficient
Rewrite as perfect squares
The vertex is the point (-1,11)
The coefficient a=-5
so
a < 0 the parabola open downward and the vertex is a maximum
