What is the slope-intercept form of the linear equation 4x + 2y = 24? Drag and drop the appropriate number, symbol, or variable

Morgarella [4.7K]

The slope-intercept form of the linear equation $4x + 2y = 24$ is $y =-2x+12$

Step-by-step explanation:

We need to write slope-intercept form of the linear equation $4x + 2y = 24$

The standard equation of slope-intercept form is:

$y=mx+b$

Converting given equation in slope-intercept form.

$4x + 2y = 24$

Add -4x on both sides

$2y = -4x+24$

Divide both sides by 2

$y =-2x+12$

So, the slope-intercept form of the linear equation $4x + 2y = 24$ is $y =-2x+12$

Find all solutions of the equation in the interval [0,2pi)

irinina [24]

Answer:

{π/4, 5π/4}

Step-by-step explanation:

Tan theta -1=0 could be rewritten as tan Ф = 1. The tangent function is 1 at Ф = π/4. As the period of the tangent function is π,

tan Ф = 1 will be true for Ф = π/4 + π, or (5/4)π.

The solution set is {π/4, 5π/4}.
