Solve for c . ab - c = 9

Nesterboy [21]

Hi

ab - c =9
Solve for c
-c = 9 - ab
Divide both sides by -1
-c/-1 = 9-ab/-1
c = -9 + ab

Good luck !

If f(x) = 2x2 + 5x - 8 and f(x) = -10,<br> which of the following could be a<br> value for x?<br> -2

alexdok [17]

Answer:

x = -2 or x = -1/2

Step-by-step explanation:

We can just set up an equation where the quadratic is equal to -10, and then solve the equation:

$2x^2+5x-8=-10\\2x^2+5x+2=0\\\\$

Now, factor:

$(2x+1)(x+2) = 0\\x=-2 \text{ or } x=-1/2$
