Answer: Well it depends on what your referring to 10+9 is 109, 9+10 is sometimes considered to be equal to 21 but that is just mere speculation the only answer to make sense has to be 910, but alas the obvious answer was wrong. By entering in the equation on a calculator your answer would be 19. I know math is ridiculous

Solve: -4x-8x+17=23<br> check solution
Sveta_85 [38]

Answer:

x = -1/2

Step-by-step explanation:

To solve the equation, we first need to combine like terms:

-12x+17=23

Simplify further:

-12x=6

Divide by -12 on both sides to get:

x = -\frac{1}{2}

To check  the solution, plug x back into the original equation and check if we get the correct answer:

-4(-\frac{1}{2})-8(-\frac{1}{2})+17=23

2+4+17= 23

23=23

Thus, it checks out and our answer is correct.

Using the quadratic formula, what is the value of x for x^2-4+5=0​
PSYCHO15rus [73]

value of x is: x= i and x= -i

Step-by-step explanation:

We need to find the value of x from x^2-4+5=0​ using quadratic formula.

The term is: x^2+1=0​

The quadratic formula is:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\

Where a = 1, b=0,c=1

Putting values:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{0\pm\sqrt{(0)^2-4(1)(1)}}{2(1)}\\x=\frac{\pm\sqrt{-4}}{2}\\x=\frac{\pm2i}{2}\\x=\pm i

So, value of x is: x= i and x= -i
