The time \(t\) (in hours) needed to produce \(x\) units of a product is modeled by \(t=p x+s .\) If it takes 265 hours to produce 200 units and 390 hours to produce 300 units, what is the value of \(s ?\) (A) 1.25 (B) 15 (C) 100 (D) 125
Use a table of values to graph the equation. Label the \(x \text { -intercept and the } y \text { -intercept. (Review } 4.2,4.3)\) $$y=-9+3 x$$
Use the following information. You are buying 20 dollars worth of bird seed that consists of two types of seed. Thistle seed attracts finches and costs 2 dollars per pound. Dark oil sunflower seed attracts many kinds of song birds and costs 1.50 dollars per pound. Write an equation that represents the different amounts of 2 dollars thistle seed \(x\) and 1.50 dollars dark oil sunflower seed \(y\) that you could buy.
Use a table of values to graph the equation. Label the x-intercept and the y-intercept. $$ y=-x+8 $$
