-6x + 5y = 1<br> 6x + 4y = –10

Firlakuza [10]

Answer:

x=-1

y=-1

Step-by-step explanation:

-6x + 5y =1 ......equation (1)

6x + 4y = –10 ......equation (2)

adding equation (1) to equation (2)

9y=-9

9y/9 =-9/9 (dividing both side by the coefficient of y)

y=-1

subtituting the value of y =-1 into equation (2)

6x+4(-1)=-10

6x+(-4)=-10

6x-4=-10

6x=-10+4(making constant to be at one side and the variable at the other side)

6x=-6

x=-6/6

x=-1

Determine the equation of the graph shown y = a(x - h)^2 + k

LUCKY_DIMON [66]

Answer:

$y=-(x+1)^2+4$

Step-by-step explanation:

we know that

$y=a(x-h)^2+k$

Is the equation of a vertical parabola written in vertex form

where

(h,k) is the vertex

a is the leading coefficient

In this problem we have

The vertex is the point (-1,4)

$(h,k)=(-1,4)$

substitute

$y=a(x+1)^2+4$

Find the value of a

we have the ordered pair (0,3)

substitute the value of x and the value of y in the quadratic equation and solve for a

$3=a(0+1)^2+4$

$3=a+4\\a=3-4\\a=-1$

therefore

$y=-(x+1)^2+4$
