Monisha decides to join a gym for a minimum of one month to train for a triathlon. The gym charges a joining fee of $100 and a monthly fee of $37. If x represents the number of months that Monisha is a member of the gym, the equation below can be used to determine C, her total membership fee for that duration of time: 100 + 37x = C Monisha has allocated a maximum of $285 to spend on her gym membership. Which number line shows the possible number of months that Monisha can be a member of the gym? A number line shows numbers from 0 to 12 in increments of 1. The portion of the line from 1 to 5 is bold with shaded circles at 1 and at 5 A number line shows numbers from 0 to 12 in increments of 1.

Your group will consist of yourself and four other friends or family members. call them A, B, C, D and E or similar. For each subject record the length of their forearm from elbow to wrist. record this number in inches and then convert it to cm. This measurement will be recorded as the x coordinate. For each student record the length of their height in feet and inches, then convert this measurement to cm. This measurement will be the subjects Y coordinate. Write each subject measurements as ordered pair. Plot all ordered pairs on a grid and convert it axes measurements to cm.Select two of the ordered pairs on your grid that seem to follow an upward trend and draw in a line connecting them.Upload the grid only as an attachment to your post.Using two ordered pairs you selected, show us how to plug them into the slope formula to find the slope of your line.Using one of your points and your slope plug them into the point slope formula and show us how to find the equation to your line .Write the equation in slope intercept form.using your equation answer question 6, Suppose a crime scene investigator uncovers a partial skeleton and identifies a bone as a human ulna ( the ulna is one of two bones in the forearm and extends from elbow to wrist) If the length of the bone is 12 in, estimate the height of the person before death.
