Which number is the common difference of the sequence -92,-74,-54,-38,-20?

2 answers:

8 0

The common difference if there is one is the constant difference that occurs between any term and the term before it.... in this case:

There is no common difference,

dx=18,20,16,18 the difference or velocity is not constant...

d2x=2, -4,2 the acceleration is not constant...

d3x=-6,6 the thrust is not constant

Now we might be tempted to say that:

d4x=12 and say that that is constant and we COULD make a quartic equation fit all the data points, but without further data points in the sequence there is no mathematical proof that the quartic equation would produce accurate data points outside of the range given...

And solving a system of five equations for five unknowns is tedious for such a problem...a^4+bx^3+cx^2+dx+e=y

0.25 (y-4)+0.07=0.22y-0.05 (60)

Georgia [21]

First, let's use distributive property and expand this equation:

0.25 (y-4)+0.07=0.22y-0.05 (60)
0.25y - 1 + 0.07= 0.22y - 3

Now, isolate the values of y and solve!

0.25y - 1 + 0.07= 0.22y - 3
0.25y - 0.22y = 1 - 0.07 - 3
0.03y = -2.07
y = -69

Hope this helps!

Determine whether the ordered pair (1, 1) is a solution of the inequality. y ≤ -3x+1

solong [7]

-------------------------------------------------------------------------------------------------------------

Answer: $\textsf{(1, 1) is NOT a solution of the inequality}$

-------------------------------------------------------------------------------------------------------------

Given: $y \le-3x + 1$

Find: $\textsf{Determine if (1, 1) is a solution of the inequality}$

Solution: In order to determine if (1, 1) is a solution we need to plug in 1 for the x values and 1 for the y values and see if the equation evaluated to true.

Plug in the values

$y \le-3x + 1$

$1 \le-3(1) + 1$

Simplify

$1 \le-3 + 1$

$1 \le-2$

As we can see the expression states that 1 is less than or equal to -2 which is false therefore (1, 1) is NOT a solution of the inequality.
