Al13 EO3 TSW6 Linear Eq. Ye Rin. Shelby. TSW 6. Linear Equation, Solving!!. Using a Table as a Check. Long. 400 students take Spanish and has been increasing 20 students per year. 98 students take German and has been decreasing 5 students per year.
Al13 EO3 TSW6 Linear Eq.
taking Spanish (400)
Number taking German (98)
Students taking Spanish will be five times than students taking German in two years!!
Using a Graph as a Check
Use a diagram.
Gazelle caught in 20 seconds
If the gazelle is closer to the cheetah than x feet, the cheetah can catch the gazelle
If the gazelle is farther away than x feet, the gazelle is in the safety zone
Distance Gazelle runs in 20 sec.
Gazelle’s starting distance from cheetah
Distance cheetah runs in 2o seconds
Gazelle’s distance = 73 x 2o (feet)
Gazelle’s starting distance from cheetah = x (feet)
Cheetah’s distance = 88 x 20 (feet)
73 x 20 + x = 88 x 20
