Answer:

x = 2, y = 5

Step-by-step explanation:

The diagonals of a parallelogram bisect each other, thus

PT = TR and QT = TS

Substitute in values

y = 2x + 1 → (1)

3y = 3x + 9 → (2)

Substitute y = 2x + 1 into (2)

3(2x + 1) = 3x + 9

6x + 3 = 3x + 9 ( subtract 3x from both sides )

3x + 3 = 9 ( subtract 3 from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

Substitute x = 2 into (1)

y = 2(2) + 1 = 4 + 1 = 5

HELP PLS!! <br> Write the inequality shown by the graph
larisa [96]

Answer: y>-2/6+2

Step-by-step explanation:

We know it's greater then so we just need to find the line. Let's look at the Slope, since 0,2 is greater than -6,4 we start there. The y of 0,2 is 2 so we subtract 4 from 2 which is -2 and now we subtract -6 from 0 which is 6 so now we have -2/6 and the intercept is 2 so we now have y=mx+b which is the line in black: y=-2/6+2. But it is greater than so its y>-2/6+2

The number of <img src="https://tex.z-dn.net/?f=x" id="TexFormula1" title="x" alt="x" align="absmiddle" class="latex-formula"> s
Alex777 [14]

Answer:

D. 4

Step-by-step explanation:

Without actually solving the equation, recall that for a=|b|, there are two cases:

\begin{cases}a=b, \\a=-b\end{cases}

In the given equation |x-2|^{10x^2-1}=|x-2|^{3x}, there are two pairs of absolute value symbols.

Since each has two cases, there must be a total of 2\cdot 2=\boxed{4} different equations created.

All four cases are:

\begin{cases}(x-2)^{10x^2-1}=(x-2)^{3x},\\(-x+2)^{10x^2-1}=(x-2)^{3x},\\(x-2)^{10x^2-1}=(-x+2)^{3x},\\(-x+2)^{10x^2-1}=(-x+2)^{3x}\end{cases}

Exponents differ, hence clearly there are four possible solutions to this equation.

You can solve for all four values of x by taking the log of both sides and using a bit of algebra to verify you have four solutions.
