Answer:R=3.6
Step-by-step explanation:
R=k/A
When R=12, A=1.5
12=k/1.5
k=1.5×12
k=18
To determine R when A =5
R=18/5
R=3.6
Answer:
An equation is linear if its graph forms a straight line. This will happen when the highest power of x is 1. Graphically, if the equation gives you a straight line then it is a linear equation. Else if it gives you a circle, or parabola, or any other conic for that matter it is a quadratic or nonlinear equation.
To solve this, add 17 to both sides:
x = -25 + 17
x = -8
C
The first binomial can have an x factored out, resulting in (x-7) and the second binomial can have a 7 factored out, resulting in (x+3)
