What is the discriminant of 9x^2+2=10x^2

Mathematics
1 answer:
Tcecarenko [31]3 years ago
3 0

Answer:

8

Step-by-step explanation:

To find the discriminant, we need to get the equation in standard form

9x^2+2=10x^2

Subtract  10x^2 from each side

9x^2-10x^2+2=10x^2-10x^2

-x^2 +2 =0

This is in the form ax^2+bx +c =0

where a=-1 b=0 and c=2

The discriminant is

b^2 -4ac

0^2 -4*(-1)*2

0+8

The discriminant is 8

The expression 7 + 2(x – 3) + 5x is simplified correctly in the correct order. Which of the steps has an incorrect justification
timama [110]

  7 + 2(x - 3) + 5x

= 7 +  2x - 6  + 5x     <em>distributed 2 into x - 3</em>

= 7 - 6  +  2x + 5x     <em>grouped like terms together</em>

=    1     +     7x

You didn't provide an image of the steps but hopefully you can figure it out based on the information I provided.

L=liters=volume=cubic meter
ml=mililiter=volume=cubic centimeter
cm^3=mililiter

cm is the answer



weight is the measurement of the amount of gravity of an object, it changes depending on where you are (on moon, something has less weight than on earth)
mass is how much matter is in something, doesn't matter where you are (on moon, still same mass as on earth)

Please Help. Thank you

The answer is D. A translation does not change a figure's size or shape because each of its points are moved the same amount and in the same direction(s).

The Earth has a mass of about 6 x 10^24 kg. Neptune has a mass of 1.8 x 10^27kg. How many times bigger is Neptune than Earth
elena-s [515]

Answer:

300 times bigger.

Step-by-step explanation:

That would be (1.8 * 10^27 ) / (6 * 10^24)

= 0.3 * (10^27/10^24)

= 0.3 * 10^3

= 3 * 10^2

= 300.
