Answer:

x=5,y=6

Step-by-step explanation:

given,  6x+2y=42................(1)

           -6x+12y=42..............(2)

adding (1) and (2)

                  6x+2y-6x+12y=42+42

                   14y=84

                     y=\frac{84}{14}

                       y=6,

y=6 put in equation (1)

6x+2times{6}=42

6x=42-12=30

x=\frac{30}{6}

x=5

A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. He started at
antiseptic1488 [7]

Answer:

W = 6t + 90

Step-by-step explanation:

Given :

Starting weight = intercept = 90 kg

Weight gained after 8 months = 138 kg

Using the slope intercept relation ;

We can obtain the rate of change, slope ;

y = mt + c

m = slope ; t = time after t months ; c = intercept

y = weight gained after 8 months

138 = 8m + 90

138 - 90 = 8m

48 = 8m

m = 48 / 8

m = 6

Hence, slope intercept equation equals :

W = 6t + 90
