The slope-intercept form:
m - slope
b - y-intercept
We have the slope m = 4 → 
and point (1, 6). Substitute:
<em>subtract 4 from both sides</em>
<h3>Answer: y = 4x + 2</h3>
The zeros of the given functions are shown on the attached picture.
Answer:
<u>t = t₀ - 3n</u>
Step-by-step explanation:
Let t be the temperature and t₀ be the initial temperature of the day
Let n be the number of hours after the initial temperature ( t₀) was registered
Let -3 be the constant of change of temperature ( In 4 hours it went down 12 degrees)
Now, let's write down the expression that shows the temperature change each hour, this way:
t = t₀ - 3n
After 2 hours
t = t₀ - 3 * 2 = t₀ - 6
After 5 hours
t = t₀ - 3 * 5 = t₀ - 15
After 3 hours and 30 minutes
t = t₀ - 3 * 3.5 = t₀ - 10.5
Answer:
5, 1, 0.2
Step-by-step explanation:
Divide the number by 5 to get the next one.
