Answer:
Step-by-step explanation:
A proportional relationship is depicted by the changes in one variable with respect to the other.
Let us test the values
Assume x = 2, 3 and 4 for all options
A) y + 4 = 3x,
y= 3x - 4
If x = 2, y = 2
if x = 3, y = 5
If x = 4, y = 8
B) y − 3x = 0
y = 3x
If x = 2, y = 6
If x= 3, y = 9
If x = 4 , y = 12
C) y + 5x = 6
y = 6-5x
If x = 2, y = -4
If x = 3, y = -9
If x = 4, y = -14
D) y + 1/4x = 2
y = 2 - 1/4x
If x = 2, y = 15/8
If x = 3, y = 23/12
If x = 4, y = 31/16
equations B and C represents a proportional relationship between the x and y values. A change in x always results to a corresponding and proportional change in y

Answer:
Last choice is correct.
Step-by-step explanation:
Given that ∠C=90°, ∠B=30°, c=10
We know that sum of all angles in a triangle is 180 degree.
∠A+∠B+∠C=180°
∠A+∠30°+∠90°=180°
∠A+∠120°=180°
∠A=60°
Now we can use sin or cos whichever applicable to find missing sides
2b=10
b=5
Similarly
a=8.6602
Hence last choice is correct.
Answer:
<h2> 40in^3</h2>
Step-by-step explanation:
Step one:
given data
dimension of the box
lengh= 5 in
width= 2 in
height =4 in
Required
the volume of the box
the expression for the volume is
V=L*W*H
V=5*2*4
V=40 in^3
Hence the volume of sand the box can take is 40in^3
