Vedmedyk [2.9K]

Given:

The system of linear equations are $x-y=4$ and $3x-2y=-5$

We need to determine the solution to the system of equations using substitution method.

Solution:

The solution can be determined using the substitution method.

Let us substitute $x=4+y$ in the equation $3x-2y=-5$

Thus, we have;

$3(4+y)-2y=-5$

$12+3y-2y=-5$

$12+y=-5$

$y=-17$

Thus, the value of y is -17.

Substituting $y=-17$ in the equation $x-y=4$ , we get;

$x+17=4$

$x=-13$

Thus, the value of x is -13.

Hence, the solution to the system of equations is (-13,-17)

The vertex of a parabola represented by f(x)=x^2 - 4x + 3 has coordinates (2,-1). Find the coordinates of the vertex of the para

Step2247 [10]

$f(x)=x^2-4x+3$
a=1, b=-4, c=3
If the vertex has coordinates (2;-1)(p=2,q=-1) we can write vertex form of a parabola equation:
$f(x)=a(x-p)^2+q$
$f(x)=1(x-2)^2-1$

We need to put (x-2) at the place of (x) in f(x) equation to get g(x)
$g(x)=1[(x-2)-2]^2-1$
$g(x)=(x-2-2)^2-1$
$g(x)=(x-4)^2-1$
So:
p=4, q=-1

Vertex of the parabola defined by g(x)=f(x-2) has the vertex at $\boxed{(4;-1)}$
