Answer:
Step-by-step explanation:
you first need to change the mixed number to an improper fraction
then multiply the second fraction by 2 so that the denominator is the same in both fractions
Answer:
2x^2 + 7x.
Step-by-step explanation:
8x^2 - 5x + 3x(4 - 2x)
= 8x^2 - 5x + 12x - 6x^2
= 2x^2 + 7x.
I assume the way it's written is like this
4x^2 - 8x + 4 - (2x^2 - 3x + 7)
If that's the case, just combine like terms.
Let's begin with 4x^2. It has the same components as the -2x^2 (remember, since it's being subtracted in the original equation, the number is negative.)
4x^2 - 2x^2 = 2x^2
Now -8x and 3x (be careful, sometimes there's a minus sign in and out of the parentheses, this makes the number positive again
-8x + 3x = -5x
And then 4 and -7
4 - 7 = -3
So the simplified version is finally:
2x^2 - 5x - 3
Hope this helped! If you need me to explain anything, don't be afraid to ask.
You would do 10,000 multiplied by 2
This equals $20,000
Hope this helps and hope I get brainliest!
P.S. I really only need 2 more brainliest to level up from Ambitious, please help a guy out!
Answer:
Elimination isn't exactly the easiest for this situation. But since the equations are in the same form and not solved for the same variable, I would go with elimination. (If they were solved for the same variable, I would go with substitution.) It would require me to make a manipulation on both equations.
I would multiply first equation by 5 and second equation by -2. The reason I would do this is because the y's would have opposite coefficients and when you add opposites you get 0.
The new set of equations would look like this:
20x+10y=45
-14x-10y=2
But I will slope here since we aren't asked to solve it.
Some texts use the term linear combination instead of elimination. They are the same.
