When a value causes a denominator in a fraction to be equal to zero, the correct response is: This fraction is undefined.

What value makes the equation −5=4−3x/4−3x undefined?(1 point)

−4/3
3/4
−3/4
4/3

To determine the value that makes the equation \(-5 = \frac{4 - 3x}{4 - 3x}\) undefined, we need to analyze the denominator \(4 - 3x\).

The expression is undefined when the denominator is equal to zero:

\[ 4 - 3x = 0 \]

To solve for \(x\):

\[ 3x = 4 \]

\[ x = \frac{4}{3} \]

Therefore, the value that makes the equation undefined is \(\frac{4}{3}\).

Solve the equation for the variable k: 30/k+1=4 .(1 point)

10
1/6
6
1/10

To solve the equation \(\frac{30}{k} + 1 = 4\) for the variable \(k\), follow these steps:

  1. Subtract 1 from both sides:

    \[ \frac{30}{k} = 4 - 1 \]

    \[ \frac{30}{k} = 3 \]

  2. Multiply both sides by \(k\) to eliminate the fraction:

    \[ 30 = 3k \]

  3. Divide both sides by 3 to solve for \(k\):

    \[ k = \frac{30}{3} \]

    \[ k = 10 \]

So the solution for \(k\) is 10.

What is the value for the variable f in 17/3f−1 =1 ?(1 point)

5
4
3

To solve the equation \(\frac{17}{3f} - 1 = 1\) for the variable \(f\), follow these steps:

  1. Add 1 to both sides of the equation: \[ \frac{17}{3f} = 1 + 1 \] \[ \frac{17}{3f} = 2 \]

  2. Multiply both sides by \(3f\) to eliminate the fraction: \[ 17 = 2 \cdot 3f \] \[ 17 = 6f \]

  3. Divide both sides by 6 to solve for \(f\): \[ f = \frac{17}{6} \]

Since \(\frac{17}{6}\) does not match any of the provided options (6, 5, 4, 3), it appears there may have been a misunderstanding of the equation.

To check, let’s go back and confirm:

The original equation is: \[ \frac{17}{3f} - 1 = 1 \]

This rearrangement and solving produce \(f = \frac{17}{6}\).

If you meant the equation is supposed to be \( \frac{17}{3f} = 2\) without the \(-1\), then:

  • Multiply both sides by \(3f\) first as shown, gives \(17=6f\), leading to \(f = \frac{17}{6}\).

Please clarify if there's an alternate equation or if there's a different approach to solving, as standard calculations yield \(f = \frac{17}{6}\), which simplifies to approximately 2.83, not one of the provided answers.
