Answer:

Neither arithmetic nor geometric

Step-by-step explanation:

Since 99-89.9= 9.1, and 89.9 - 78.8 = 11.1, the sequence is not arithmetic.

Likewise 89.9/99=0.908 and 78.8/89.9 = 0.876 makes it not a geometric sequence

What is -3x^2-4x-4=0

ss7ja [257]

Answer:

<h2>no real solution</h2>

Step-by-step explanation:

$-3x^2-4x-4=0\qquad\text{change the signs}\\\\3x^2+4x+4=0\\\\\text{use the quadratic formula:}\\\\\text{for}\ ax^2+bx+c=0\\\\\text{if}\ b^2-4ac0,\ \text{then an equation has two solutions:}\ x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

$\text{We have}\ a=3,\ b=4,\ c=4.\\\\\text{Substitute:}\\\\b^2-4ac=4^2-4(3)(4)=16-48=-32$

Which equation is equivalent to 2 Superscript 4 x Baseline = 8 Superscript x minus 3?

marshall27 [118]

Answer:

2 Superscript 4 x Baseline = 2 Superscript 3 x minus 9

8^(x-3) = 2^(3x-9)

Step-by-step explanation:

2⁴ × 8^(x - 3)

2⁴ × (2³)^(x-3)

2⁴ × 2^(3x - 9)

Since the bases are same now, powers can be added

2^(4 + 3x - 9)

2^(3x - 5)
