Answer:

Postive 5 and negative 9.

Step-by-step explanation:

So remember, all we have to do is set each of the parethese to zero and solve. It should look like this:

x-5=0 and x+9=0

For the first equation we have made, jsut add 5 to both sides so x is alone. This will get you:

x=5

So the first answer for x is 5.

Now lets solve our second equation and find the second answer for x.

So all we have to do for this one is subtract 9 from both sides. This should get you:

x=-9

<u>So now we know that our two answers for x is 5 and -9.</u>

<u>These two answers seem to be on your list as #2 answer and #3 answer.</u>

Answer:

5, -9

Step-by-step explanation:

(x - 5)(x + 9) = 0    These are factors, to get the roots, just set each one equal to zero

x - 5 = 0

x = 5

x + 9 = 0

x = -9

Which correctly describes how to determine the measure of angle 1? 2 parallel lines are crossed by a transversal to form 8 angle
-BARSIC- [3]

Answer:

m∠1 = 99°

Step-by-step explanation:

∠2 and ∠81° are Corresponding Angles, so they are equal to each other:

∠2 = 81°

∠1 and ∠2 are Supplementary Angles, so they add up to 180°:

180 - m∠2 = m∠1

180 - 81 = 99°

Two less than 3/2 of a number (x) is more than 5 1/2
garik1379 [7]

Answer:

3/2x-2>5 1/2

Step-by-step explanation:

Two less than a number means we are subtracting 2, so we can write it into the equation as -2.

Since we dont know the value of x, we can just write 3/2 of x by multiplying 3/2 by x. So 3/2x. Also, since we are subtracting two from 3/2x, -2 comes after 3/2x.

Now, since it says that it is more than 5 1/2, we could use the greater than sign (>), to express that. So >5  1/2

Our final expression is 3/2x-2>5 1/2.

Hope this helps!
