Given: RS = 3x - 16 ST = 4x - 8 RT = 60 Solve for RS.

1 answer:

8 0

RT = RS + ST
60 = 3x -16 + 4x -8
60 = 7x - 24
84 = 7x
84/7 = 7x/7
12 = x

RS = 3x - 16
RS = 3(12) - 16
RS = 36 - 16
RS = 20

1. $y=7x-1$

2. $y=3x+b$
 Sub (1, -5) into equation to find 'b'
$-5=3(1)+b$
$-8=b$

$y=3x-8$

3. $x=-7$

4. $y=4$
