Plz which relationship is always correct for the angles p, q, and r of triangle abc? a triangle abc has angle abc labeled as q, angle bca labeled as r, and the exterior angle at a labeled as p. a. p + r = q b. p + q + r = 180 degrees c. p + q + r = 90 degrees d. q + r = p

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.

Simone claims the initial value and y-intercept are the same thing on a graph. is she correct? if you know that a line has a slope of and a y-intercept of 7, what is the equation for that line in slope-intercept form?

The border line of the linear inequality 4x + 7y < 5 is dotted true or false?
