Find the 7th term of the arithmetic sequence 5x + 9, 8x + 5, 11x + 1,...

ohaa [14]

Answer:

Step-by-step explanation:

In arithmetic sequence: a₂ - a₁ = a₃ - a₂ {common difference}

$a_1=5x+9\\a_2=8x+5\\a_3=11x+1\\\\\\d=8x+5-(5x+9)=8x+5-5x-9=3x-4\\\\a_n=a_1+d(n-1)\\\\a_7=5x+9+(3x-4)\cdot6\\\\a_7=5x+9+18x-24\\\\a_7=33x-15$

The equation of the line that goes through the point (−10,8) and (−3,-4) can be written in the form y=mx+b

Y_Kistochka [10]

Answer:

m is -12/7 and b is -64/7

Step-by-step explanation:

Use rise over run (change in y / change in x) to find the slope, m:

(-4 - 8) / (-3 + 10)

= -12/7

So, m is -12/7.

Plug in this value and a point into y = mx + b, then solve for b:

y = mx + b

-4 = -12/7(-3) + b

-4 = 36/7 + b

-64/7 = b

So, m is -12/7 and b is -64/7
