Answer:

-0.5

Step-by-step explanation:

Use the simultaneous equations method:

x - 4y = 6

3x + 4y = 10

Add these two equations together to cancel out 'y':

4x = 16

Divide both sides by 4:

x = 4

substitute this value into one of the equations:

(4) - 4y = 6

Subtract 4 from both sides:

- 4y = 2

Divide both sides by -4:

y = -0.5

goodluck!

What is the vertex of the graph y= x^2 + 6x - 5

Rashid [163]

we are given

$y= x^2 + 6x - 5$

Firstly ,we can find equation in vertex form

so, we will complete x square

$y= x^2 + 6x+3^2-3^2 - 5$

$y= (x+3)^2-3^2 - 5$

$y= (x+3)^2-14$

now, we can compare it with vertex form of equation

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

we can find h and k

$h=-3 , k=-14$

so, vertex is

$(h,k)=(-3,-14)$ .............Answer
