Answer:
- The function is a linear function.
- The function changes at a constant rate.
Step-by-step explanation:
The degree of x is 1, so the function is a linear function.
The coefficient of x is -90, a constant rate of change that is negative, so the function is <em>decreasing</em>.
Answer:
<h2>D= 3.9 miles</h2>
Step-by-step explanation:
Given data
speed v= 13 miles per hour
time taken t= 20min to hour 0.3 hours
the distance D
We know that the relationship between speed, time, and distance
speed=distance/time
13=D/0.3
(the expression above describes the relationship between distance, speed, and time)
making D subject of formula we have
D= 0.3*13
D= 3.9 miles
hence the distance is 3.9miles
Answer:
(- 1, 3)
Step-by-step explanation:
To find the y- coordinate, substitute x = - 1 into the equation
y - 3 = 2(x + 1) ( add 3 to both sides )
y = 2(x + 1) + 3 ← substitute x = - 1
y = 2(- 1 + 1) + 3 = (2 × 0) + 3 = 0 + 3 = 3
To write down notes while you are in the class because I find it easier to explain it to yourself. You can use flashcards or study your textbook. I find the first suggestion best.
