Answer:
Step-by-step explanation:
3/4 x -18 = 1/4 x -4
subtract 1/4 x from each side
3/4 x -1/4 x -18 = 1/4 x- 1/4 x -4
2/4 x - 18 = -4
add 18 to each side
1/2 x -18 + 18 = -4 + 18
1/2 x =14
multiply by 2 on each side
2* 1/2 x = 14 * 2
x =28
Answer:
Quadratic
Step-by-step explanation:
For two lines to be parallel, their slope must be the same.
To find the slope, we can use the form:
For the top line, the change in height (y value) can be seen as a - 0 or simply a, and the change in base is just -b (because our
is just 0, from the origin.
Hence, line 1's gradient is:
Now, we can repeat this process for line 2:
Change in height is -d, change in base is c
Hence, line 2's gradient is:
For the two lines to be parallel, both gradients must be the same:
