Subtract the following polynomials, then place the answer in the proper location on the grid. write the answer in descending powers of a.

subtract: 11a2 + 42a - 6 from 14a 2 - 24a + 7.

let w represent lizette's walking speed. then her running speed is w+6. the relationship between speed, time, and distance is

  distance = speed × time

lizette ran for 1.5 hours, then walked for 3 hours. her total distance is

  (w+6)·1.5 + w·3 = 18

  4.5w + 9 = 18 . . . simplify

  4.5w = 9 . . . . . subtract 9

  w = 2 . . . . . . divide by 4.5

lizette's walking speed is 2 mph; her running speed is 8 mph.

the slope-intercept form:

m - slope

b - y-intercept

we have the slope m = -3 and the y-intercept b = 1. substitute:

it is a linear function. we need only two points to plot the graph.

select two values of x. put them in the line equation and calculate the values of y.

for x = 0:

for x = 1:
