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

step-by-step explanation:

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
