Answer:

see explanation

Step-by-step explanation:

To obtain the first 5 terms substitute n = 1, 2, 3, 4, 5 into the rule

a_{1} = \frac{1+1}{1} = 2

a_{2} = \frac{2+1}{2} = \frac{3}{2}

a_{3} = \frac{3+1}{3} = \frac{4}{3}

a_{4} = \frac{4+1}{4} = \frac{5}{4}

a_{5} = \frac{5+1}{5} = \frac{6}{5}

crimeas [40]

Answer:

(10, –1)

Step-by-step explanation:

[1]XXXX3y=−12x+2

[2]XXXXy=−x+9

While it is not technically necessary, I find it easier to clear the fractions before actually beginning; so multiplying [1] by 2

[3]XXXX6y=−x+4

Substituting (from [2]) (−x+9) for y in [3]

[4]XXXX6(−x+9)=−x+4

Simplifying

[5]XXXX−6x+54=−x+4

[6]XXXX5x=50

[7]XXXXx=10

Substituting (from [7]) 10 for x in [2]

[8]XXXXy=−10+9=−1

70% of a number is 98.
Reika [66]
Let 70% of X = 98

70%.x = 98

(70/100).x = 98

0,7x = 98

x = 98/0,7

x = 140


Then, 90%x = 90%.140

= 0,9.(140)

= 126

The answer to this question is Letter D)


I hope this has helped.

The graph of which function is decreasing over the interval (–4, ∞)? f(x) = (x + 4)2 + 4 f(x) = –(x + 4)2 + 4 f(x) = (x – 4)2 –
kow [346]

Your post would be clearer if you'd please put each function on its own line:


f(x) = (x + 4)2 + 4

f(x) = –(x + 4)2 + 4

f(x) = (x – 4)2 – 4

f(x) = –(x – 4)2 – 4


Also, use "^2" to denote "squaring." x2 has no meaning.


f(x) = (x + 4)^2 + 4 has a parabolic graph with vertex (-4,4). It increases steadily once x is greater than -4. Reject this choice.


f(x) = –(x + 4)^2 + 4 has a parab. graph with vertex (-4,4) also. It decreases steadily once x is greaster than -4. This is the answer.


Analyze the other 2 possible answers in the same way, please.
