Answer:
x = 10
Step-by-step explanation:
X = 10 because if you look at the 28 and 14, 14 is half of 28 so the ratio is 1:2 which would also work for the 20 so the answer is 10
Answer: n > 6.85
Step-by-step explanation: So the orignal question was 13 < 4n – 14.4 and you want to know how to solve it.
13 < 4n – 14.4
27.4 < 4n (You add 14.4 to both sides to get n by itself)
27.4/4 < 4n (You divide both sides by 4 to get just n)
6.85 < n (This is because 27.4/4 is 6.85)
I hope this helps

Answer:
D.
Step-by-step explanation:
If the slope is in a straight, horizontal line, it means the slope is 0. Horizontal goes from left to right, or sideways.
Now, substitute the coordinates (4, -4) to each of the equations below, it has to make sense: Remember: (x, y)
a. y = 1/4x
Sub: -4 = 1/4(4)
-4 = 1?
Incorrect
b. y = x - 4
Sub: -4 = 4 - 4
-4 = 0?
Incorrect
c. y = -x + 8
Sub: -4 = -1(4) + 8
-4 = -4 + 8
-4 = 4?
Incorrect
d. y = -1/2 - 2
Sub: -4 = -1/2(4) - 2
-4 = -2 - 2
-4 = -4?
Correct
In conclusion, d is the correct answer to this problem.
