Since -1 is less than or equal to -1 you input it into the first equation.
-3•(-1) -4
3-4
-1
the answer is -1 good luck
You are given two points that could be plotted on a graph (1,-5) and (4,1). The formula for slope is y2-y1/x2 -x1
When plotted into the points it would look like 1-(-5)/4-1= 6/3
6/3=2. So, the slope for these two points is 2.
Given :
The equation below can be used to determine I (simple interest) on a loan as follows :
...(1)
P is principal, r the rate of the loan, t is the length of the loan in years.
We need to find the equation to solve in terms of r. We can find the value of P.
Dividing both sides of equation (1) by rt. So,

So, P can be solved as :
.
