Answer: False

<u>Step-by-step explanation:</u>

In order for lines to be perpendicular, their slopes must be opposite reciprocals.

y=-\dfrac{5}{2}x+4\qquad \rightarrow \quad m=-\dfrac{5}{2}\\\\\\y=\dfrac{5}{2}x-3\qquad \rightarrow \quad m=\dfrac{5}{2}

Their slopes are opposites (opposite signs). \checkmark

Their slopes are NOT reciprocals (fractions flipped) X

Congruent means same so the equation is
5x+24=9x-17
Subtract 5x on both sides
24=4x-17
Add 17 to both sides
41=4x
Divide by 4

Solve for x if 10/4x-3 = 2​
Marysya12 [62]

Answer:

We need to solve this equation:

\frac{10}{4x}-3=2

We pass -3 to the right summing:

\frac{10}{4x} = 2 + 3

\frac{10}{4x}=5

We pass the 4x that is dividing to the right multiplying:

10 = 5*4x

10=20x

We pass the 20 of the right to the left dividing:

\frac{10}{20}=x

x=\frac{1}{2}

Now, we know x=\frac{1}{2}, so we can verify:

\frac{10}{4*\frac{1}{2}}-3 = 2

\frac{10}{2}-3=2

5 - 3 = 2 TRUE
