Kelly tells you that when variables are in the denominator, the equation one over two plus three over x equals three over four b

ecomes unsolvable. Kelly explains, "There is a value for x that makes the denominator zero, and you can't divide by zero." Demonstrate to Kelly how the equation is still solvable and explain your reasoning.

1/2 + 3/x = 3/4
multiply everything by x
1/2x + 3 = 3/4x...subtract 1/2x from both sides
3 = 3/4x - 1/2x
3 = 3/4x - 2/4x
3 = 1/4x...multiply both sides by 4
4 * 3 = x
12 = x

Does anyone knows how to do that? <br> I need to solve for x
vesna_86 [32]

Answer:

x=17°

Step-by-step explanation:

Because the diagonal lines are marked with arrows, we know that they are parallel. The two angles that are marked with measures are same-side interior angles. Same-side interior angles of parallel lines are supplementary, meaning that the sum of their measures is 180°.

Now, with all of this information, we can set up the following equation and solve for x:

115+4x-3=180

112+4x=180 (Simplify LHS by combining like terms)

112+4x-112=180-112 (Subtract 112 from both sides of the equation to isolate x)

4x=68 (Simplify)

\frac{4x}{4}=\frac{68}{4} (Divide both sides of the equation by 4 to get rid of x's coefficient)

x=17° (Simplify)

Hope this helps!

A function is a special relationship where each input has a single output.
therefore :
A is not a function; x=0;  ⇒y₁=3; y₂=4
C is not a function; x=2;⇒ y₁=1; y₂=8
D is not a function; x=1;⇒y₁=2, y₂=-3

only B is a function; each input has a single output.
