The expression which is not equivalent to other three is dt = r
What is an expression?
Numbers, symbols and operators grouped together that show the value of something.
Given are the four expressions, d = rt, dt = r, d /t = r, d/r = t
2) dt = r
d = r/t
3) d/t = r
d = tr
4) d/r = t
d = rt
Hence, we can say the expression dt = r is unequal to the other three.

Step-by-step explanation:
-8(2)-[3(-5)-(-1)+4(2-6)]+4(-7)
opening the brackets
-8(2)-[-15+1+4(-4)]+4(-7)
-8(2)-[-15+1+4(-4)]+(-28)
-8(2)-[-15+1+(-16)]-28

Final answer:
The equation y = -3x - 1 represents a straight line with a slope of -3 and y-intercept of -1. The graph will be a line falling to the right and crossing the y-axis at -1.
Explanation:
The question asks which graph represents the equation y = -3x - 1. This is a linear equation, where the coefficient of 'x', -3 here, gives us the slope of the line, and the constant, -1 here, gives us the y-intercept. A slope of -3 means for each step of 1 increase in x, the value of y decreases by 3. The y-intercept is the point where the line intersects with the y-axis, in this case at y = -1.
A graph representing this equation will be a straight line with a slope of -3 (indicating the line falls as we move along the positive x-axis) and will cut the y-axis at y = -1.

So now we have a simpler version to work with.
To further simplify, we can divide both sides by
Now, we can work it out to find the completely simplified inequality, which would simply be
n < 4
The character '<' represents that the number being represented by the variable is less than the number that follows that character. On a proper number line, this is represented by an open circle above the number on the right of the inequality with an arrow pointing the same direction on the number line that the point of the inequality symbol is facing.
If that doesn't make sense, imagine the inequality symbol as the head of an arrow.
<====<<
So the arrow would be pointing to the left, with an open circle above the 4. The only choice listed that represents this is the second option down.
Option B is your correct answer choice.
Hope that helped! =)
