1/2*(6*1+7)+11 show the result
fomenos
Well I got 17.5
You would start with                              6x1=6
Then you would add 7:                         6+7=13
Next you would multiply 13 by (1/2):    13(1/2)=6.5
Finally you would add 11 to 6.5:           6.5+11= 17.5

Got a fairly simple looking system of equations, 2k+4y=20, and 3x+6y=30 Don't understand how to prove what values of k provide -
Leya [2.2K]

Answer:

2kx+4y=20 ⇒ kx+2y=10

3x+6y=30 ⇒ x+2y= 10

k is the coefficient of x, so it is the slope of the line

  • when k=1, both equations will be same, then there are many solutions
  • when k=0 there is one solution
  • when k is anything different, then the lines will be parallel, so no solutions
