Answer:
0.23 centimeters per hour
Step-by-step explanation:
Answer:
2y = 3x - 8
y = 3/2x - 4
Work
-2x + 5(3/2x - 4) = -9
-2x + 15/2x - 20 (+20) = -9 (+20)
-4/2x + 15/2x = 11
11/2x * (2/11) = 11 (2/11)
x = 2
3(2) - 2y = 8
6 (-6) - 2y = 8 (-6)
-2y = 2
y = - 1
final answer:
x = 2
y = -1

Answer: 1560 = 30(52) + b
Step-by-step explanation:
Based on the information given in the question, the straight line passes through two points which are (40, 1200) and (52, 1560). Then, the equation if the straight line will be:
y - 1560 = (1200 - 1560)/(40 - 52) (x - 52)
y - 1560 = (-360)/(-12) (x - 52)
y - 1560 = 30(x - 52)
Lets put the value of x to be 0.
y - 1560 = 30(x - 52)
y - 1560 = 30(0 - 52)
y - 1560 = -30(52)
Therefore, 1560 = 30(52) + b
