Answer:

B

Step-by-step explanation:

5x^2 -3x+10 = 5x^2

Subtracting 5x^2 from each side

5x^2-5x^2 -3x+10 = 5x^2-5x^2

-3x+10 =0

We cannot use the quadratic formula since a =0

Answer:

B

Step-by-step explanation:

The answer is B because when you simplify it you get -3x + 10 = 0. Since this is no longer a quadratic equation, you can't solve it using the quadratic formula.

sattari [20]

Answer:

Yes. Plug in your x and y into the first given equation and you'll see why.

7 ≥ -1 (7 is greater than or equal to -1)

...As well as the second equation.

(7) < 4(2)+2

7 < 8+2

7 < 10 (7 is less than 10)

What is the answer to 3x+2-x=11x-9
Elenna [48]
3x+2−x=11x−9
Step 1: Simplify both sides of the equation.
3x+2−x=11x−93x+2+−x=11x+−9(3x+−)(2)=11x−9
(Combine Like Terms)
2x+2=11x−92x+2=11x−9

Step 2: Subtract 11x from both sides.
2x+2−11x=11x−9−11x−9x+2=−9

Step 3: Subtract 2 from both sides.
−9x+2−2=−9−2−9x=−11

Step 4: Divide both sides by -9.
−9x−9=−11−9x=119

Plea for help
melomori [17]

Let x be the number that Xavier is thinking of.

Now let's "translate" the words into an equation:

9 + 4x = 2x - 15

This simplifies to 2x = -24, which gives x = -12.

Hope I get a brailest so I can be a new level hope that help!
