Y intercept : (0,-15)
X intercept : (3,0)
Slope : (0 - (-15)) / (3-0) = 15 / 3 = 5

Answer:
- -2.2(6) +1.8(4) . . . temperature change
- 42 °C
Step-by-step explanation:
At the end of the first 6 hours, the temperature change was ...
(-2.2 K/h)(6 h) = -13.2 K
The change in the next 4 hours was ...
(1.8 K/h)(4 h) = 7.2 K
Then the total change over the 10-hour period was ...
(-2.2)(6) +(1.8)(4) . . . . . expression for temperature change
This evaluates to -13.2 +7.2 = -6.
__
The final temperature is the sum of the initial temperature and the temperature change:
final temperature = 48 °C -6 °C = 42 °C
_____
<em>Additional comment</em>
When temperature is measured on the Celsius scale, a change of 1 degree is called a kelvin (K).
Answer:
Well for constructing your gonna need a compass and measure the length of the line your constructing and a drawing is just a free draw without a compass perpendicular lines are straight on both sides

is ..................................b.3
Answer:
x > -3
Step-by-step explanation:
–3x + 6 < 15
Subtract 6 from each side
–3x + 6-6 < 15-6
-3x < 9
Divide each side by -3, remembering to flip the inequality
-3x/-3 > 9/-3
x > -3
