-2 = g - 9 solve equation
jekas [21]

OK.  Hold on tight.  Here we go.
Remember ... the "solution" is the number that 'g' must be
in order to make the equation a true statement.

The original equation:   You said that  -2 = g - 9

Now, let's add  9  to each side:             7 = g .

Given: 1; -5; -13 ; -23 ; ...<br><br> Derive a formula for the nth term in the pattern.
mylen [45]

Answer:

  f(n) = -n^2 -3n +5

Step-by-step explanation:

Suppose the formula is ...

  f(n) = an^2 +bn +c

Then we have ...

  f(1) = 1 = a(1^2) +b(1) +c

  f(2) = -5 = a(2^2) +b(2) +c

  f(3) = -13 = a(3^2) +b(3) +c

__

Here's a way to solve these equations.

Subtract the first equation from the second:

  -6 = 3a +b . . . . . 4th equation

Subtract the second equation from the third:

  -8 = 5a +b . . . . . 5th equation

Subtract the fourth equation from the fifth:

  -2 = 2a

  a = -1

Then substituting into the 4th equation to find b, we have ...

  -6 = 3(-1) +b

  -3 = b

and ...

  1 = -1 +(-3) +c . . . . . substituting "a" and "b" into the first equation

  5 = c

The formula is ...

  f(n) = -n^2 -3n +5

Describe how you would use the Distributive Property to simplify (39 × 5). (2 points)
alexandr402 [8]
Use of distributive property will be
(30 x 5) + (9 x 5)

21. the error for x - 28 = 375 is not 347 is because the student subtracted both sides by 28. 347 - 28 is 319 not 375. One must add 28 to both sides of -28 and 375. The -28 and 28 is zero. 375 + 28 = 403.

22. The next three terms are 0.93, 1.02, and 1.11. The rule in the number pattern is one must add 0.09.

Ben walks 500 meters from his house to the corner store. He then walks back toward his house, but continues 200 meters past his
lbvjy [14]

Answer:1.2 m/s

Step-by-step explanation:

Total distance covered is 500+500+200 m so the average velocity is given by

V = distance/time

V=1200/(17*60)

V=1.176 m/sec
