4b - 6c = 11
c + b = 12
4c + 4b = 48
10c = 39
c = 3.9
b = 12 - 3.9
b = 8.1
Answer:
Part A: 2k(2c2+5(2)-8c-20)
Part B: sorry i don't know how to do this part
Step-by-step explanation:
Part A, you divide each number by 2 first so you get a simplified version of each number. Then, you will quickly realize that the varible k is similar in all of the numbers then you remove that and put it with the 2 outside the (). Hope you understood my explination.
Answer:
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
By definition, the slopes of perpendicular lines are negative reciprocals.
Given the line:
We know that a line perpendicular to this line must have this slope:
Since that line goes through the point (8,2), we can substitute the slope 1 and these coordinates into and solve for "b":
Therefore, the equation of this line is:
