Answer:

3

Step-by-step explanation:

S is a point on line segment RT.

So RS+ST=RT.

(7y-1)+(y+5)=28

Combine like terms:

8y+4=28

Subtract 4 on both sides:

8y=24

Divide both sides by 8:

y=3

1. PLEASE HELP. Consider the matrices-
Alex

Answer:

A - B  =  [  -1  3  ]

             [ -6  2  ]

             [ -4 -10 ]

Step-by-step explanation:

Since Matrix A and Matrix B have the same size, then we can simply perform the operation of subtraction on each position within the matrices to get the resulting subtracted matrix.

A =  [  4  7  ]              B =  [  5  4  ]

      [ -3  8  ]                     [  3  6  ]

      [ -5 -2  ]                    [  -1  8  ]

A - B  =  [ (4 - 5)  (7 - 4) ]

             [ (-3 - 3) (8 - 6) ]

             [ (-5 - -1) (-2 - 8) ]

A - B  =  [  -1  3  ]

             [ -6  2  ]

             [ -4 -10 ]

Cheers.
