Roy and Sam start solving the equation as follows.

denpristay [2]

Answer:

The correct option is D.

Step-by-step explanation:

The given equation is

$-3x+4=5x-6$

According to the addition property of equality $a=b$ and $a+c=b+c$ are equivalent equations.

Use addition property of equality, add 3x on both the sides.

$-3x+4+3x=5x-6+3x$

$4=8x-6$

Therefore Sam's work is incorrect because he make calculation mistake.

According to the subtraction property of equality $a=b$ and $a-c=b-c$ are equivalent equations.

Use subtraction property of equality, subtract 5x from both the sides.

$-3x+4-5x=5x-6-5x$

$-8x+4=-6$

Therefore Roy's work is correct because he used subtraction property.

Option D is correct.

The following table shows the cost for a person to go to the 4 - H Fair to go on a certain number of rides: Develop an equation

PtichkaEL [24]

In order to develop an equation, let's use the slope-intercept form of the linear equation:

$y=mx+b_{}$

Using the points (3, 13.5) and (5, 18.5) from the table, we have:

$\begin{gathered} (3,13.5)\colon \\ 13.5=3m+b \\ (5,18.5)\colon \\ 18.5=5m+b \end{gathered}$

Subtracting the second and the first equation:

$\begin{gathered} 5m+b-(3m+b)=18.5-13.5 \\ 2m=5 \\ m=2.5 \end{gathered}$

Now, finding the value of b:

$\begin{gathered} 13.5=3m+b \\ 13.5=7.5+b \\ b=13.5-7.5 \\ b=6 \end{gathered}$

So the equation that represents this table is y = 2.5x + 6

Looking at the options, the correct one is E (none of the above).
