Step-by-step explanation:

b(n) = b(1) + (n-1) d, where d is the difference,

d = 13-(-5) = 18

b(n) = (-5) + (n-1)(18)

= -5 +18n -18

b(n) = 18n -23

.......... is the slope zero
Eddi Din [679]

Answer:


Step-by-step explanation:

OK... You have to use this formula: <u>Y2 - Y1</u>

                                                          X2 - X1

  • -2 represents X1
  • 7 represents Y1
  • 2 represents X2
  • -5 represents Y2    

<u>Y2 - Y1</u>

X2 - X1

<u>-5 - 7</u>

2 - - 2

<u>-12</u>

-2

Simplify by dividing both -12 & -2 by 2: <u>-6</u>

                                                                 -1

It's either <u>-6</u> or it's just -6 by itself... Really sorry if I'm wrong...

                -1

10. A weight hangs on a spring. The vibration period of that weight is the time in which it makes a complete cycle in motion. Su
Alenkinab [10]

The vibration period of the spring will be 0.2 seconds

<em><u>Explanation </u></em>

The relationship between the vibration period "T" (in seconds) and the weight "w" (in kilograms) is given by...

T= 2\sqrt{\frac{w}{200}}

Given that, the weight(w) = 2.0 kilograms

So, <u>plugging w = 2.0</u> into the above equation, we will get...

T= 2\sqrt{\frac{2.0}{200} } \\ \\ T= 2\sqrt{\frac{1}{100} }\\ \\ T= 2*\frac{1}{10}\\ \\ T= \frac{1}{5}=0.2

So, the vibration period of the spring will be 0.2 seconds.

What are some ways we can tell that 7x + 2 is not equivalent to 9x?
vlabodo [156]

Answer:

To determine if two fractions are equivalent, cross multiply. To cross multiply, you multiple the numerator of the first fraction by the denominator of the second. Then you multiply the denominator of the first fraction by the numerator of the second. If the two numbers are equal, the fractions are equivalent
