Answer:
2 > x is your answer.
Step-by-step explanation:
Isolate the variable x. Add 10x & subtract 20 from both sides.
56 (-20) - 10x (+10x) > 20 (-20) + 8x (+10x)
56 - 20 > 8x + 10x
Simplify.
56 - 20 > 8x + 10x
36 > 18x
Isolate the variable x. Divide 18 from both sides
(36)/18 > (18x)/18
36/18 > x
2 > x
2 > x is your answer.

Answer: The answer is 2 > x.
Step-by-step explanation:
Hi, to solve this expression we have to isolate the variable:
56-10x>20+8x
First we have to subtract 20 from both sides of the expression:
56- 10x -20 > 20 + 8x -20
-10x +56 -20 > 8x +20-20
-10x +36 > 8x
Then, we have to add 10x from both sides.
10x -10x +36 > 8x +10x
36 > 18x
Finally, we have to divide by 18 each side:
36/18 > 18x/18
2 > x
In conclusion, the answer is 2 > x.

Answer:(-6,-5)
Step-by-step explanation:
The slope is -2/3
Table 1
Table 2
Neither table
Table 1
X 3 4.5 7 Y 7.5 11.25. 17.5
Table 2
X 1.5. 8 13. Y 3. 12. 19.5
Answer:
You can tell if it has direct variation by finding the slope and inserting it and the coordinates into point slope form.
You can find the slope by putting both sets of coordinates into the equation
y - y / x -x , where the first y and x are from one set of coordinates, and the next two are from the other set.
(7.5 - 3) / (11.25 - 4.5)
4.5 / 6.75
The slope is 2/3
Next, input the slope and the origin (0,0) into point-slope form.
y - y = m (x - x) Substitute.
y - 3 = 2/3 (x - 4.5) Distributive Property.
y - 3 = 2/3x - 8/15 Add 3 to both sides.
y = 2/3x + 37/15 Simplify.
y = 2/3x + 2 2/15
So you know that the line does not go through origin, because its y-intercept is 2 2/15.
For the second one do the same things.
y -y / x - x
(3 - 1.5) / (12 - 8)
1.5 / 4
3/8
y - y = m ( x - x )
y - 3 = 3/8 (x - 12)
y - 3 = 3/8x - 24/8
y = 3/8x - 0
y = 3/8x
So the second one goes through the origin because its y-intercept is 0. The answer is Table 2 has direct variation.
