Answer:

No, it doesn't.

Solve the above equation for y .

y 2= 1 - x

y = + √(1 - x) or y = - √(1 - x)

For one value of x we have two values of y and this is not a function.

15. 3x - 2y = -2
3x - 3x - 2y = -3x - 2
   -2y = -3x - 2
      -2    -2
   y = 1.5x + 1

y - y₁ = m(x - x₁)
y - 3 = ⁻²/₃(x - (-2))
y - 3 = ⁻²/₃(x + 2)
y - 3 = ²/₃(x) - ²/₃(2)
y - 3 = ⁻²/₃x - 1¹/₃
   + 3 + 3
   y = ⁻²/₃x + 1²/₃

Is the sequence geometric? if so what is the common ratio/answers 2,-4,-16,-36/

VLD [36.1K]

Answer:

We conclude that the sequence 2, -4, -16, -36,... is not a geometric sequence.

Step-by-step explanation:

Given the sequence

2, -4, -16, -36,...

A geometric sequence has a constant ratio 'r'.

Let us compute the ratio of all the adjacent terms

$\frac{-4}{2}=-2,\:\quad \frac{-16}{-4}=4,\:\quad \frac{-36}{-16}=2.25$

It is clear that the ratio is not constant.

Thus, the given sequence is not a geometric sequence.

Therefore, we conclude that the sequence 2, -4, -16, -36,... is not a geometric sequence.

Solve 2x² - 11x + 5 = 0.

goldenfox [79]

Answer:

x=1/2, x=5

Step-by-step explanation:

2x^2-11x+5=0

Factor them

(x-0.5)(x-5)

x=0.5 or 1/2

x=5
