Plz find x and y WILL GIVE BRAINLIEST!!!!!!

Elina [12.6K]

Answer:

x=-2 and y=2

Step-by-step explanation:

Do simultaneous equations

-8x + 4y = 24 (multiply everything in the equation by -7)

-7x + 7y = 28 (multiply everything in the equation by 8)

56x - 28y = -168

-56x + 56y = 224

(add equations, ie add 'x' parts, 'y' parts, and numerical parts)

28y = 56

∴y = 2

-8x + 4y = 24

-8x + 4(2) = 24

-8x = 16

∴x=-2

Lemme know if you have questions :D

Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of y=4x^2+5x-1

Ivanshal [37]

Answer:

Axis of symmetry: $x=-\frac{5}{8}$

Vertex: $(-\frac{5}{8},-2\frac{9}{16})$

Step-by-step explanation:

The given quadratic equation is

$y=4x^2+5x-1$

By comparing to the general quadratic function; $y=ax^2+bx+c$

We have a=4,b=5,c=-1

The equation of the axis of symmetry is given by the formula;

$x=-\frac{b}{2a}$

We got this formula by completing the square on the general quadratic function.

We substitute a=4 and b=5 to obtain;

$x=-\frac{5}{2(4)}$

$x=-\frac{5}{8}$
is the axis of symmetry.

To find the y-value of the vertex, we put $x=-\frac{5}{8}$ into the function to obtain;

$y=4(-\frac{5}{8})^2+5(-\frac{5}{8})-1$

$y=4(-\frac{5}{8})^2+5(-\frac{5}{8})-1$

$y=-\frac{41}{16}$

The vertex of the given function is $(-\frac{5}{8},-2\frac{9}{16})$
