Answer:
D
Step-by-step explanation:
Given
x = 6 - x² ( subtract 6 - x² from both sides )
x² + x - 6 = 0 ← in standard form
Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (+ 1)
The factors are + 3 and - 2, since
- 3 × 2 = - 6 and 3 - 2 = + 1, thus
(x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 2 = 0 ⇒ x = 2
Sum of solutions = - 3 + 2 = - 1 → D
Answer:
if two angles are supplementary angles, then the sum of their angle measures is equal to 180°.
Step-by-step explanation:
the if p statement is called the hypothesis of the conditional statement.
the then q statement of the conditional statement is called the conclusion.
Answer:
x=6 or x=2
Step-by-step explanation:
Step-by-step explanation:
- h(x)=f(x)-g(x)
- h(x)=3^x-3^2x-3^x
- h(x)=3^x(1-3²-1)
- h(x)=3^x(-9)
- h(x)= -27^x
hope it helps.
