The number three that is being added to the fraction goes on the x axis determiner where you start. The u use the fraction and -3 is the y and -2 or two is the x
8a+12b because you multiply 2 by each number. For example 4a times 2 is 8a and 6b times 2 is 12b
Hope that helped :)
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.
Answer: 7 hours
Explanation: We can use the equation 93=9h+30 to represent the problem.
When we solve for h with (93-30)/9, we get 7 hours.
