Given:

The system Mx+Ny=P has a solution (1,3) where Rx+Sy=T; <span>M, N, P, R,S and T are non-zero real numbers.

Solve for M, N, R, P, S, T:

M +3N = P
R + 3S = T

The given choices should simplify to the equations above. 

A) Mx +Ny = P
     7Rx + 7Sy = 7T
     7(Rx + Sy) = 7T
     Rx + Sy = T
remarks: CORRECT

B) (M+R)x + (N+S)y = P +  T
    Rx + Sy = T
     Mx + Rx + Ny + Sy = P + T
     Mx + Ny + T = P + T
     Mx + Ny = P
remarks: CORRECT

C) Mx + Ny = P
    (2M - R)x + (2N - S)y = P - 2T
    2Mx - Rx + 2Ny - Sy = P - 2T
    2(Mx + Ny) - (Rx + Sy) = P - 2T 
    2P - (Rx + Sy) = P - 2T
remarks: INCORRECT

What is the result of converting 6 inches into centimeters
svetlana [45]

The conversion rate is 1 inch = 2.54 cm. So for this, we will have to multiply 6 times 2.54 to get the length in centimeters.

6 x 2.54 = 15.24

6 inches equals 15.24 cm.

Hope that helps!

Answer:

  (a) not proportional

  (b) k = 7/8

Step-by-step explanation:

When a linear equation is of the form ...

  y = mx + b

with b ≠ 0, the relation is NOT PROPORTIONAL.

__

If b=0, so the equation is of the form ...

  y = kx

then the relation IS PROPORTIONAL. The constant of proportionality is k.

__

(a) Not proportional

(b) Proportional with k = 7/8
