John baked 12 cakes, 50 muffins, and 42 pastries on friday. his goal for saturday is to bake 3 times as many of each item. if represents his production for friday, which matrix represents his production for saturday?

X_sat   =

Step-by-step explanation:

Let,

x = number of cakes produced

y = number of muffins produced

z = number of pastries produced

Friday

x = 12

y = 50

z = 42

X =production

X_friday =  =

His goal for Saturday is to bake 3 times as many of each item

X_sat = 3*X_friday

X_sat  = 3*  

X_sat   =   

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
