The equation has to be set to something otherwise it is just an expression. I will assume that you mean 3x+60=0 in which case x equals negative 20
Y = -1x + b
Plug in equation
-6 = -1(2) + b
-6 = -2 + b, b = -4
Solution: y = -1x - 4
Answer:
<h2>A = 145 cm</h2><h2 />
Step-by-step explanation:
total length = 445 cm (A + B + C)
A = 45 + B
B = C/2
find A
A + B + C = AC
(45 + B) + (C/2) + C = 445
45 + C/2 + C/2 + C = 445
2C = 445 - 45
C = 400/2
C = 200
B = 200/2
B = 100
A = 45 + 100
A = 145
proof:
445 = 145 + 100 + 200
445 = 445 ----OK
