1.7 Literal Equations video practice

What defines a literal equation?

• An equation that only contains numbers.

• An equation that contains only one variable.

• An equation that is all variables or has more than one variable, solved for one.

• An equation that always results in a numerical answer.

What is the first step to solve the equation 3x - 4y = 12 for y?

• Divide both sides by -4.

• Add 4y to both sides.

• Subtract 3x from both sides.

• Add 12 to both sides.

When the equation 3x - 4y = 12 is solved for y, what is the resulting equation in slope-intercept form?

• y = -3x + 12

• y = (3/4)x - 3

• y = 3x - 12

• y = (-3/4)x + 3

To solve the formula V = l * w * h for w, what operation should be performed?

• Divide both sides by l and h.

• Multiply both sides by l and h.

• Subtract l and h from both sides.

• Add l and h to both sides.
