Answer:

2a-5 over 6a^2.

Step-by-step explanation:

2/7a - 5/a^2. If you multiply 2/7a by a you can give them the same denominator and subtract them.

2a/7a^2 - 5/a^2.

2a-5 over 7a^2 - a^2.

2a-5 over 6a^2.

ASAP PLEASEwrite an equation for the line that is parallel to tue given line and that passes through the given point. y=-5x+3; (

max2010maxim [7]

Answer:

$y=-5x-27$

Step-by-step explanation:

Since we are finding a parallel line, the slopes will be the same, so the second equation will also have a slope of -5.

Then, to find the y-intercept, we can use the point given and plug in.

$y=-5x+b$

$3=-5(-6)+b$

$3=b+30$

$b=-27$

So the equation comes out to be $y=-5x-27$

We can check by plugging in the given point again.

$3=-5(-6)-27$

$3=30-27$

$3=3$
