2) x=5 it is this because first u distribute the -2 to both the x and the +1 which gets you -2x-2=-12 then you add 2 (you add because you have to do the opposite of subtracting when you need to isolate the variable) to both sides to isolate 2x so you are left with 2x=10 then to get x all by itself you divide 2 to both sides so you are left with x=5
3) x=6 it is this because first you have to add 8 to both sides because you are doing the opposite to subtracting to get 7x alone so you get 7x=18+4x then you subtract 4x from both sides and get 3x=18 then divide 3 to both sides and you get x=6
4) a=2 it is this because first you distribute 3 into 6a and +12 which gets you 18a+36 , so you new equation will be 18a+36+4a=80 then you combine like terms so you combine 18a and 4a and you add them together to get 22a so your new equation is now 22a+36=80 then you subtract 36 from both sides to isolate 22a you are now left with 22a=44 then you divide 22 to both sides which leaves you with a=2
SORRY THIS IS A LOT! I TRIED TO EXPLAIN THE BEST I CAN! HOPE THIS HELPS :) have a nice day !
Answer:
y = (-1/2)x
Step-by-step explanation:
As we go from (-4, 2) to (6, -3), x (the "run") increases by 10 and y (the "rise") decreases by 5. Thus, the slope of the line connecting these two points is m = rise / run = m = -5/10, or m = -1/2.
We adapt the slope-intercept form as follows: y = mx + b becomes
2 = (-1/2)(-4) + b, or
2 = 2 + b. Therefore, b must be 0. The desired eequation is y = (-1/2)x.
Answer:

Answer:
Step-by-step explanation:
Find the dimensions of the kitchen, convert to feet
- 5 in * 20 = 100 in = 100/12 ft = 25/3 ft
- 4 in * 20 = 80 in = 80/12 ft = 20/3 ft
<u>The area is</u>
- 25/3 * 20/3 = 500/9 = 55.56 ft² (rounded)
