What is the common difference d of the sequence nine -8 -25 -42 -59

Answer:

The common difference d in the given sequence is -17

Step-by-step explanation:

We need to find the common difference d of the following sequence 9 -8 -25 -42 -59

We have a₁ = 9

and a₂ = -8

The formula used is: a_n=a_1+(n-1)d

By putting values we can find the value of d

We have n=2, a₂ = -8, a₁ = 9 and we need to find d

a_n=a_1+(n-1)d\\a_2=a_1+(2-1)d\\-8=9+d\\d=-8-9\\d=-17

So, the common difference d in the given sequence is -17

Step-by-step explanation:

<u><em>Definition of: Coefficient</em></u>

A number used to multiply a variable.

<u><em>Example:</em></u> 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.

Variables with no number have a coefficient of 1.

<u><em>Example</em></u>: x is really 1x.

<em><u>coefficients:</u></em>

3<em>x⁴</em>+ 5<em>x²</em> + 1<em>x</em>

<u><em>sum of the coefficients:</em></u>

3 + 5 + 1

8 + 1

Write an equation in slope intercept form for the line that passes through (2,-2) and is parallel to y=-5/2x+5
DENIUS [597]

y=mx+b\\y=x-2

<em>Only y= x - 2 intercepts x-axis at 2 and y-axis at -2. Thus meaning that they intercept oppositely.</em>

<em>Find if both graphs are parallel, that means the equation must be false.</em>

<em />x-2=-\frac{5}{2}x+5<em />

<em>Multiply whole equation by 2 to get rid of the fractional 2.</em>

<em />2x-(2)(2)=-\frac{5}{2}(2)(x)+5(2)\\ 2x-4=-5x+10\\2x-4+5x-10=0\\7x-14=0\\7x=14\\x=2<em />

<em>Well, that doesn't seem to be parallel. This is called one solution answer. Both graphs intercept at (2,0). There are no linear graphs that intercept at (2,-2) except for y = x-2 so there are no graphs with (2,-2) that are parallel to the equation y = -5x/2+5 </em>
