Substitute all x's:

a. -6 - 7 = -6 + -7 = -13. Choice A is wrong
b. -9 + 8 = -1. Choice B is wrong
c. -36 + 8 = -26. Choice C is wrong
d. 1/2(-6 - 6) = -6. Choice D is correct.

-6 - 6 = -6 + -6 = -12
-12 / 2 = -6

The answer is choice D.

Hope this helped☺☺

What is the 7th term in the geometric sequence described by this explicit formula?an = –3 • (3)(n – 1)
I am Lyosha [343]

Answer:

7th term = -2187


Step-by-step explanation:

The formula for nth term of a geometric sequence is given by:

a_n=a*r^{n-1}

Where

  • a is the first term,
  • r is the common ratio,
  • n is the nth term (term number)

Since the question gives us the formula and wants to know 7th term, we just plug in 7 into n:

a_n=(-3)*(3)^{n-1}\\a_n=(-3)*(3)^{7-1}\\a_n=(-3)*(3)^6\\a_n=-2187

5. x2 +5x-4<br> Discriminate
ikadub [295]

Answer:

<em>D = 41</em>

Step-by-step explanation:

y = ax² + bx + c

The discriminant D = b² - 4ac tells the types of roots the equation has.

If D < 0 , then quadratic equation has no real roots, has two imaginary roots.

If D = 0 , then quadratic equation has one real root.

If D > 0 , then quadratic equation has two distinct real roots.

~~~~~~~~~~~~

x² + 5x - 4

a = 1, b = 5, c = - 4

<em>D </em>= 5² - 4(1)(- 4) = 25 + 16 =<em> 41</em>
