Answer:

\large\boxed{a=-3,\ b=-7\ and\ c=3}

Step-by-step explanation:

ax^2+bx+c=0

We have:

-3a^2=7a-3          <em> subtract 7a from both sides</em>

-3a^2-7a=7a-7a-3

-3a^2-7a=-3           <em>add 3 to both sides</em>

-3a^2-7a+3=-3+3\\\\-3a^2-7a+3=0\to a=-3,\ b=-7, c=3

Answer:

Draw an open circle on 3 and shade to the left.

Step-by-step explanation:

First, solve the inequality.

x - 6 < -3

x - 6 + 6 < -3 + 6

x < 3

The less than symbol (<) indicates that 3 is not part of the solution set. Therefore, the circle will be open.

Since the inequality indicates that x is less than 3, shade to the left of 3.

Hope that helps. :)

So like tell me the answer I think it’s like either 3 or 6a^9 but I’m not sure
Iteru [2.4K]

I'm not sure what you mean by 3 or 6a^9, since there are only variables in the photo, but we can try breaking it down.

Let's start with the bottom,

a^2 * a^3 would be a^5 because for exponents you add the exponents of what's multiplied (product rule)

Then using the quotient rule, where you subtract the exponents, a^5/a^5 = a^(5-5)

And anything to the 0th power is 1, so your answer should be 1

Hope that helps!
