Independent variable (IV): something the scientist can change.
Thus, in this case, the IV can be the weight of the person.
If you are reffering to this dot plot, it would be 13 trees being studied.
Hope you won't be turned off by a correction, but we really need to use the symbol " ^ " to denote exponentiation.
Thus, we have x^2 = 100
Taking the square root of both sides, we get x = plus or minus 10. Verify, please, that both x = -10 and x = +10 satisfy the given equation.
Answer:
x = - 8, x = - 4
Step-by-step explanation:
x² + 12x + 32 = 0 ← in standard form
(x + 8)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 8 = 0 ⇒ x = - 8
x + 4 = 0 ⇒ x = - 4
\left[y \right] = \left[ 81+32\,x\right][y]=[81+32x] being converted to vertex form
