Answer: B
Option is B) y-3x=0 represents a proportional relationship between the x and y values
Explanation:
Case 1 = y+4=3x
From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 4 .
Case 2: y-3x=0
From the above equation we can see that if we change the value of x, the value of y changes by proportionality.
Hence the correct option is B.
Case 3 = y+5x=6
From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 6.
Case 4 = y+1/4×x=2
From the above equation we can see that if we change the value of x, the value of y does not changes by proportionality due to the presence of 2.
Answer:
130/81
simplified: 1 49/81
Step-by-step explanation:
I did the math
What is that ? are you joking ?
Answer:
1. x = -15
2. x = 0.25 or x = 1/4
Step-by-step explanation:
1.
8 + 9.8x + 9 = 3.8x - 16 + 3.8x
Simplify both sides
17 + 9.8x = 7.6x - 16
-17 -17
9.8x = 7.6x - 33
-7.6x -7.6x
2.2x = -33
Divide by 2.2
x = -15
2.
-2x - 10 = -14x - 7
+7 +7
-2x - 3 = -14x
+2x +2x
-3 = -12x
Divide by -12
0.25 = x
x = 0.25 or x = 1/4
