Step-by-step explanation:
Needing to find the circumference of a circle you you find that you need to use the equation C=2 π R
C= 28.26
this is how much fence they would need around the garden approximately.
y=−3x+9 slope of this equation is -3 and y-intercept is 9
Plot the y -intercept first which is 9 and mark the points using the slope which is -3. Join the points. So blue line in the graph is y = -3x+9
y=−x−5 slope of this equation is -1 and y intercept is -5
Plot the y -intercept first which is -5 and mark the points using the slope which is -1 . Join the points. So pink line in the graph is y = -x-5
The intersection point of these two lines gives you the solution.
The coordinates of point of intersection (7,-12)
Independent variable (IV): something the scientist can change.
Thus, in this case, the IV can be the weight of the person.
