Gerald purchased 55 paving stones to use in his garden. the graph shows points representing the number of stones left to place at several different times while gerald is working. a function graph of a line segment having three points (0,55), (3,40) and (7, 20) with an x axis of zero to twelve hours and a y axis of zero to sixty paving stones left select from the drop-down menus to complete the equation, in standard form, that represents the relationship between the number of paving stones left to place, y, and the time, x, gerald has spent working. x + y =

The slope of the equation can be solve by:

 m = (20 – 55)/(7 – 0) = -5

using one point (0, 55) to solve the equation:

y – y1 =m ( x – x1)

y -55 = -5( x – 0)

5x +y = 55

Gerald can finish his job when y = 0 it is when x = 11 hrs

it will be a cylinder. with a diameter of 8 and 4 single pieces high

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
