Plz me i need lesson 11: linear functions unit test algebra 1 a, part 2 unit 2: linear functions i cant fail this class plz
the first question is,
for the data in the table, does y vary directly with x? if it does , write an equation for the direct variation.
x | y
8 |28
16 |56
20|70
a.)yes; y=5x
b.)yes; x+20
c.)yes; 3.5x
d.) no; y does not vary directly with x
plz its for connections

Step-by-step explanation:

Divided y by x:

28/8 = 3.5

56/16 = 3.5

70/20 = 3.5

so y = 3.5x

Yes, y varies directly with x; y = 3.5x

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
