For every 10 degrees Celsius, degrees Fahrenheit goes up 18, so
10 degrees C is 50
20 degrees C is 68
30 degrees C is 86
40 degrees C is 104
If the line does not have a y int, then it means it does not cross the y axis....that means it is a vertical line.....its x int is (3,0)...so this equation for the line is x = 3
if the line does not have an x int, it means it does not cross the x axis...that means it is a horizontal line...its y int is (0,-4)...so the equation for this line is
y = -4
(-x-14)^2 = x^2 +14x+14x+196
which turns into x^2+28x+196.
hope this helps
and give thanks
The last graph provided is the correct one. With points (-1,-3) (-3,0) (-3,-3)
Add the two speeds together, then divide the two, this gives the average speed. Hope this was helpful!
