Can you factor -20x^2+26x+6

Mathematics

saul85 [17]3 years ago
5 0
The first thing I'd do would be to reduce this equation.  Divide all terms by 2:

-10x^2 + 13x + 3 = 0

Then I'd use the quadratic formula.  The roots would be

       -13 plus or minus sqrt(169-4(-10)(3) )
x = -----------------------------------------------------
                             -20

Can you simplify this?  Hint:  sqrt(289) = plus or minus 17.

Which are correct representations of the inequality –3(2x – 5) < 5(2 – x)? Select two options.
fenix001 [56]

A number line from negative 3 to 3 in increments of 1. An open circle is at 5 and a bold line starts at 5 and is pointing to the right.

<h3>Which is the correct representation of the inequality?</h3>

Here we have.

-3(2x - 5) < 5*(2 - x)

First, we need to isolate x in one side, let's expand both sides:

-6x + 15 < 10 - 5x

15 - 10 < 6x - 5x

5 < x

This will be represented with a number line where we have an open circle at 5, and an arrow that goes to the right. So the correct option is:

"A number line from negative 3 to 3 in increments of 1. An open circle is at 5 and a bold line starts at 5 and is pointing to the right."

A: 182<br> B: 140<br> C: 72<br> D: 18<br><br> The answer is D: 18. Explain why
Minchanka [31]

Answer:

D: 18

Step-by-step explanation:

Airplanes = 36%

Automobiles = 53%

Trains =         2%

----------------------------

                   91%    Chose these types of transportation

The rest chose boats

100% - 91% = 9%

So 9% chose boats

People who chose boats = people surveyed * percent who chose boats

200 people were surveyed and 9% = .09 chose boats

People who chose boats = 200 * .09

                                          = 18
