If 5x+15y=45 then 6x-18y=?

1 answer:

4 0

So we have 5x+15y=45
simplify and undistribute 5 from both sides
5(x+3y)=5(9)
divide both sides by 5
x+3y=9
multiply both sides by 6
6x+18y=54

if it was 6x+18y then the answer is 54
if it was 6x-18y, then I don't know the answer

Dont even know where to start

Answer:

$\displaystyle M = ( 3,1 )$

Step-by-step explanation:

we are given the endpoint i.e P and Q of a line segment

we want to figure out the Midpoint of the Line segment

in order to do so we can use Midpoint formula given by

$\displaystyle M = \bigg( \frac{ x_{1} + x_{2} }{2} , \frac{ y_{1} + y_{2}}{2} \bigg)$

so let

$x_1=-2\\x_2=8\\y_1=-2\\y_2=4$

substitute

$\displaystyle M = \bigg( \frac{ - 2 + 8}{2} , \frac{ - 2 + 4}{2} \bigg)$

simplify addition:

$\displaystyle M = \bigg( \frac{ 6}{2} , \frac{ 2}{2} \bigg)$

simplify division:

$\displaystyle M = ( 3,1 )$

hence,

the Midpoint of the line segment is (3,1)

Answer:

The point is located at (0,7) is correct

The point is on the y-axis. is correct

Step-by-step explanation:

The point is located at (7,0). is wrong because first the x values comes and then y values come here the x value is 0 and y value is 7

The point is on the x-axis.this is also wrong as you can see that the point lies on y axis not x axis
