13+2=15+1=16 that is the answer
Answer:
slope is 2 or 2/1 and y intercept is -7
Step-by-step explanation:
y=mx+b
mx= slope
b= y intercept
X2, or 2X or X times 2, or X•2.

Answer:
The width which gives the greatest area is 7.5 yd
Step-by-step explanation:
This is an application of differential calculus. Given the area as a function of the width, we simply need to differentiate the function with respect to x and equate to zero which yields; 15-2x=0 since the slope of the graph is zero at the turning points. Solving for x yields, x=7.5 which indeed maximizes the area of the pen
