Karyn knits a sweater at an average rate of 1.5 inches per evening. Four days after she first notes her rate, the sweater is 10 inches long. Let L(t) be the length of the sweater t days after having been started. Write the linear equation for L(t) in the slope-intercept form.

Linear equation = R = 0.6L

Step-by-step explanation:

Rate of knitting is directly proportional to Length.

R = KL

K = R/L = 1.5/2.5 = 0.6

Hence linear equation =

R = 0.6L

50x5=$250

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
