Answer:
Kevin is 6
Step-by-step explanation:
Let k represent Kevin's age now. Then Brendon's age now is (k-3). Two years ago the relationship of their ages was ...
k-2 = 4((k-3) -2)
k -2 = 4k -20 . . . . . eliminate parentheses, collect terms
3k = 18 . . . . . . . . . . add 20-k
k = 6 . . . . . . . . . . . . divide by 3
Kevin is 6 now.
Answer:
{x | x ≤ -20}
Step-by-step explanation:
x + 17 ≤ -3
Subtract 17 from each side
x + 17-17 ≤ -3-17
x ≤ -20
Answer:
( 1.5, 0)
Step-by-step explanation:
1. Find the coordinates ; in this case (7,-2) and (-4, 2)
2. Plug it into the formula (x1 + x2 ÷ 2 ) , (y1 + y2 ÷ 2)
3. ( 7 + -4 ÷2) = 1.5 And ( -2 + 2 ÷ 2) = 0
4. Therefore, the midpoint is ( 1.5, 0 )
