The equation: y = 2x/3 + 4 is a line with infinite values for x. So unless you have a y-value to plug in to find the corresponding x-value all you can do is write the equation in terms of y.
x = 3(y-4)/2
The slope and intercepts on the other hand can be determined from the given equation. y= mx + b is slope-intercept form of a linear equation. "m" is the slope and "b" is the y-intercept. Plug in y = 0 to find the x-intercept.
Average time of a commuter train trip from one town to the city = 77 minutes
Time taken by 1 trip = 71 minutes
Time taken by another trip = 74 minutes
Time taken by 3rd and 4th trip each = 78 minutes
Let us assume the time taken during the 5th trip = x
Then
(71 + 74 + 78 +78 +x)/5 = 77
301 + x = 77 * 5
301 + x = 385
x = 385 - 301
= 84 minutes
So the length of the fifth trip was 84 minutes. I hope the procedure is clear enough for you to understand.
72 triangles will be displayed I believe....
All you do is multiply 2 times 36 and you get 72. Because there are 2 triangles in one square, so 2*36.
Hope this Helps!
Answer:
A property of a function is that it gives one output for an input
if a function gives one output for an input, it is a function and otherwise it is not a function otherwise
here, we can see that we have 2 outputs for the input '6'. therefore, it is NOT a function
