Which function is linear? a) f(x) = |7x| + 2 b) f(x) = 1 7x + 2 c) f(x) = 7x − 2 d) f(x) = |7x| − 2

Step-by-step explanation:

The equation of alinear function in slope-intercept form:

m - slope

b - y-intercept

A) f(x) = |7x| + 2  NO because we have absolute value of 7x

B) f(x)=17x + 2   YES, slope = 17 and y-intercept = 2

C) f(x) = 7x - 2   YES, slope = 7 and y-intercept = -2

D) f(x) = |7x| - 2   NO because we have absolute value of 7x

answer: 32.68

step-by-step explanation:

x=2

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
