K=1/3

simplify each bracket, put all numbers on the left hand side, equal it to 0 and solve for k

If you start with Malvin’s age, take half of it, increase that result by 5, then divide by 3, and finally double that, you get 8

Kisachek [45]

Answer:

24 years old

Step-by-step explanation:

Let Malvin's age be x.

x / 2
x / 2 + 5 = 5x / 10 [ By taking the L.C.M.]
( 5x / 10 ) * ( 1 / 3 ) = 5x / 30 [ Multiply with the reciprocal of 3 ]
( 5x / 30 ) * 2 = 5x / 15

Now let's solve the equation,

5x / 15 = 8

5x = 8 * 15

5x = 120

x = 120 / 5

x = 24

Therefore, Malvin is 24 years old.

y=5/3x

this is because f(x)=x is one of (identity function) the 12 basic functions and when you multiply it it will shift it on the y axis

If you were to do y=x+5/3 it would make a horizontal shift to the left 5/3

So the unit your on is mostly about knowing the number located in the function that will make the graph shift different ways

Answer: y=5 x=11

abc=def

ab=de <b=<e

17y-8=12+13y 11x-4=117

-13y -13y +4 +4

4y-8=12 11/11x=121/11

+8 +8 x=11

4/4y=20/4

y=5
