Answer:

No Real Solutions

Step-by-step explanation:

Move the constants to the left now your equations is x^{2}-7+8=0

Now you calculate -7+8=0 now your equation is x^{2}+1=0

Calculate the discriminant: Determine the number of solutions using the discriminant D=b^{2}-4ac

D=0^{2}-4 x 1 x 1

Simply the expression

D= -4

Since D<0, the quadratic equation has no real solutions

Answer:

I don't think there are any solutions... (No solution)

Step-by-step explanation:

x^{2}=-7-8

Simplify

x^{2}=-15

To isolate x square both sides:

\sqrt{x}=\sqrt{-15

-15 cannot be squared since it is negative. Therefore, there is no solution.

What is 6/13 rounded to the nearest half?
prohojiy [21]
6/13, when turned into a decimal, is equal to 0.4615384615... And so on. That decimal can be rounded to the nearest hundredth to become 0.46.

Is 0.46 closer to 0.5, or 0? When put on a number line, we can see how close it is to 0.5, which is the same as 1/2.

6/13, rounded to the nearest half, is 1/2.
Hope this helped =)
