Mell is twice as old as Jerry. If 16 is subtracted from Mell’s age and 16 is added to Jerry’s age, their ages will be equal. Wha
irga5000 [103]

Answer:


Step-by-step explanation:

Let J = Jerry's age

Let M = Mary's age = 2J

 

M - 16 = J + 16

 

Substitute 2J for Mary's age

 

2J - 16 = J + 16

2J - J - 16 = 16

J = 16 + 16

J = 32

 

Jerry is 32.

Mary is twice as old as Jerry.

Mary is 2(32) = 64

Answer:

 y = -1/3x + 3 2/3

Step-by-step explanation:

step 1. find the slope of the given line

y2-y1/x2-x1          2 - 4/ 3 + 3 = - 1 / 3

take the opposite of that and there is your slope

step 2. plug in the values to the following equation using the given point:

y - y1 = m ( x - x1 )          y - 4 = - 1/3 ( x + 1 )

step 3. solve for y

y-4 = -1/3(x+1)

-1/3(x) and -1/3(1)  ----> y-4 = -1/3x-1/3

y-4+4 = -1/3x-1/3+4  ---->  y = -1/3x + 3 2/3

<em>hope this helps. if you need more help lmk in the comments. i am in algebra two so you can trust me. Happy holidays</em>
