Ur question makes no sense what so ever? what di u mean ?

**Answer:**

**Step-by-step explanation:**

y - 7 = -4(x - 0)

y - 7 = -4x + 0

y = -4x + 7

**Answer:**

k = d + 3

k - 2 = 4( d - 2 )

**Step-by-step explanation:**

Let k be Kevin's age and Let d be Daniel's age.

Given : Kevin is 3 years older than Daniel.

i.e. Age of Kelvin = Age of Daniel+ 3

i.e. In terms of variables , k= d+3 (1)

Two years ago,

Age of Kelvin = k-2

Age of Daniel = d-2

Since Two years ago ,Kevin was 4 times as old as Daniel.

i.e. In terms of variables : k -2 = 4 x (d-2)

k-2=4(d-2) (2)

From (1) and (2) the system of equations represents this situation are

k = d + 3

k - 2 = 4 ( d - 2)

You would do, 4,200 over 8,000 equals x over 500,000 and then

x*8000=4200*500000

8000 = 2100000000

divide

x= 262500
