Answer:
LM+MN=LN
3x-5+x+7=17
4x=17+5-7
4x=15
x=15/4=3.75
LM= 3x-5=3*3.75-5=6.25
Step-by-step explanation:
C (1,8) and (4,5). To interpret a system of equations when shown a graph, look for the points at which the two function intersect or meet. in this case they meet at both points (1,8) and (4,5)
It says that a piece of one 1.75 ft./s. means 1.75x, and when it says, "how long will it take to transfer you to 280ft," its telling you to plug in 280 to 1.75 which is multiplying 1.75(280),
which the answer is: 490 seconds
Hope it helped :)
Graph both equations on one coordinate plane. Wherever the equations intersect is your answer.
