Answer:

S=45m+15

Step-by-step explanation:

we have

E------>the number of sit-ups

m---->  the time in minutes

S----> the number of sit-ups after drinking the sports drink

E=15m+5 ----> equation A

S=3E ----> equation B

substitute the equation A in the equation B

S=3(15m+5)

S=45m+15

Can someone please help me please I really need help please help
mr Goodwill [35]

Answer:

  • K'(4, -4)
  • L'(8, -4)
  • M'(8, 8)
  • N'(4, 8)

Step-by-step explanation:

Dilation centered at the origin multiplies every coordinate value by the scale factor.

  K(1, -1) ⇒ K' = 4(1, -1) = (4, -4)

  L(2, -1) ⇒ L' = 4(2, -1) = (8, -4)

  M(2, 2) ⇒ M' = 4(2, 2) = (8, 8)

  N(1, 2) ⇒ N' = 4(1, 2) = (4, 8)

  Cos = Adjacent/Hypotenuse

The leg adjacent to angle B is "a". The hypotenuse is "c", so the desired cosine is ...

  cos(B) = adjacent/hypotenuse = a/c
