Answer:

(x,y)=(-2,3)

Step-by-step explanation:

6x+5y=3

x=-(13/2)+(3/2)y

6(- 13/2+3/2y) +5y=3

y=3

x=13/2+3/2x3

x=2

Step-by-step explanation:

let 6x+5y=3 be equation 1

and 2x-3y=-13 be equation 2

Multiply equation 2 by 3

(2x-3y)*3=(-13)*3

6x-9y=-39

Now Solving eq 1 and 2 simultaneously

6x+5y=3

6x-9y=-39

- + =+

_________

0+14y=42

y=42/14

y=3

Put y=3 in eq 1 to find x

6x+5y=3

6x+5(3)=3

6x+15=3

6x=3-15

6x=-12

x=-12/6

x=-2

Therefore y=3

x=-2

find the equation for the line that passes through the point (4,-3), and that is perpendicular to the line with the equation y=

Grace [21]

Answer:

Step-by-step explanation:

Answer

Slope between two given points (1,3) and (2,7) is

2−1

7−3

Then perpendicular slope is m

−1

The line equation with this slope is given by

−1

x+c.......(1)

Now, the above line passes through the point (−4,−3)

⇒−3=

−1

×(−4)+c

⇒c=−4

Therefore required line is 4y+x+16=0 (Substitute

′

in (1) and simplify)

5y+30 5 complete the factoring ...?

krek1111 [17]

Well, I don't really understand if it is 30 or 305 because of the spacing but I'll answer both. If it is 5y+305, just divide the whole equation by 5 and it will look like this (<u>5y+305)</u> then the factor would be 5(y+61)<u>
</u> 5
If it is 5y+30 it would be just in the same process, Divide the equation by 5 and the result will be 5(y+6).
