Answer:

a = 1

Step-by-step explanation:

Given the point (a, 3) is on the line: 5x + y = 8.

Any point on the line satisfies the equation.

So, (a, 3) should satisfy the equation 5x + y = 8

Substituting x = a and y = 3, we get:

5(a) + 3 = 8

$ \implies 5a = 5 $

⇒ a = 1

Therefore, (1, 3) is the point on the line.

8n−7y−12n+5−3y

=8n+−7y+−12n+5+−3y

Combine Like Terms:

=8n+−7y+−12n+5+−3y

=(8n+−12n)+(−7y+−3y)+(5)

=−4n+−10y+5

What’s Distribute -x(5x+2)
MaRussiya [10]

Answer:

-5x^2-2x

Step-by-step explanation:

When distributing, you multiply the term outside the brackets to all the terms in brackets.

If the term outside the bracket is negative, then when distributing/opening the brackets, the signs of the terms changes.

So in this prob. -x would multiply to both +5x and +2

-x*5x+-x*2

∴-5x^2-2x
