Answer:

m2=5/6 m=-6/5

Step-by-step explanation:

two axes are perpendicular if the product of their slopes is equal to minus 1

first we find the slope for the axis we are given

-6x-5y=-5

this can also be written as

y= $\frac{-6}{5} x$ +1

-6/5 is the slope

-6/5*m2=-1

m2=5/6

this is the slope for the perpendicular axis

two lines are parallel if their slopes are equal

the slope for our line is -6/5 so the slope for the parallel line is also -6/5

Answer:

The values of x and y to the given equation are x=3 and y=-1

The solution to the given equation is (3,-1)

Step-by-step explanation:

Given equations are $-2x+3y=-9\hfill (1)$

$x+y=2\hfill (2)$

To solve given equations by using elimination method :

Mutliply the equation (2) into 2 we get

$2x+2y=4\hfill (3)$

Now adding the equations (1) and (3)

$-2x+3y=-9$

$2x+2y=4$

_______________

$5y=-5$

$y-\frac{5}{5}$

Therefore y=-1

Now substitute the value of y=-1 in the equation (1) we get

-2x+3(-1)=-9

-2x-3=-9

-2x=-9+3

$=-\frac{-6}{-2}$

Therefore x=3

The values of x and y to the given equation are x=3 and y=-1

The solution to the given equation is (3,-1)

If m<1=6x+50 and m<2=4x+40 find x

Pepsi [2]

$\text{Adjacent angles on a straight line sum up to 180} \textdegree$

$\text{Therefore }\measuredangle 1 + \measuredangle 2 = 180 \textdegree$

$\text {Since } \measuredangle 1 = 6x+50 \text { and } \measuredangle 2 = x+40$

$(6x+50) + (4x+40) = 180$

$6x+50 + 4x+40 = 180$

$10x+90 = 180$

$10x = 180 - 90$

$10x = 90$

$x = 9$

Answer: x = 9
