Please solve and show your work! <3 have a great day! 12x-18y*-90
1 answer:
Simplifying
12x + -18 = 90
Reorder the terms:
-18 + 12x = 90
Solving
-18 + 12x = 90
Solving for variable 'x'.
████████████████████████████████████████████
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + 12x = 90 + 18
Combine like terms:
-18 + 18 = 0
0 + 12x = 90 + 18
12x = 90 + 18
Combine like terms:
90 + 18 = 108
12x = 108
Divide each side by '12'.
x = 9
Hence,
x = 9
Hope this helps! <3

Answer:
(6,-1)
Explanation:
The slope of the line can be calculated using the following formula:
slope =
We are given that:
slope = -0.75
point (x1,y1) is (-2,5)
We will use each of the given points to calculate the corresponding slope, then compare the calculated slope with the given one.
For point (6,-1):
slope =
= -0.75 ........> accepted choice
For point (2,8):
slope =
= 0.75 ........> rejected choice
For point (-5,1):
slope =
= 4/3 ........> rejected choice
For point (1,1):
slope =
= -4/3 ........> rejected choice
Therefore, the first option is the only correct one.
Hope this helps :)
