<span>3(x + 5) = 3 · x + 3 · 5</span>
Formula of the sum of the 1st nth term in a Geometric Progression:
Sum = a₁(1-rⁿ)/(1-r), where a₁ = 1st term, r = common ratio and n= rank nth of term (r≠1)
Sum = (-11)[1-(-5⁸)] /[(1-(-5)]
Sum = (-11)(1- 390625)/(6)
SUM = 716,144
The answer would be:
y=-\frac{2}{1}x-4
Hope this helps
In a direct proportion, the equation can be set up as
y = kx
k = y/x
k = 6/20
k = 0.3
Get all the x terms on one side, and the w on the other.
Add 37x on both sides to get 56x+rx=w.
Use the distributive property backwards to get x(56+r)=w.
Divide by 56+r on both sides to get x=w/(56+r)
