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 $y =-2x+12$

Zoltan has a list of whole numbers, all larger than 0 but smaller than 1000. He notices that every number in his list is either

timama [110]

The largest number of different whole numbers that can be on Zoltan's list is 999

<h3>How to determine the largest number?</h3>

The condition is given as:

Number = 1/3 of another number

Number = 3 times another number

This means that the list consists of multiples of 3

The largest multiple of 3 less than 1000 is 999

Hence, the largest number of different whole numbers that can be on Zoltan's list is 999

Which two values of x are roots of the polynomial below?

Julli [10]

Answer:

B. and C.

Step-by-step explanation:

1. Set the polynomial equal to zero:

x² + 5x + 7 = 0

2. Plug the given values of a, b, and c into the quadratic formula:

$x=\frac{-5+-\sqrt{5^{2}-4(1)(7) } }{2(1)}$

3. Solve the square root:

$x=\frac{-5+-\sqrt{25-4(1)(7)} }{2(1)}$

$x=\frac{-5+-\sqrt{25-28} }{2(1)}$

$x=\frac{-5+-\sqrt{-3} }{2(1)}$

4. Simplify the rest:

$x=\frac{-5+-\sqrt{-3} }{2}$

5. Separate the solutions:

$x=\frac{-5+\sqrt{-3} }{2} , x=\frac{-5-\sqrt{-3} }{2}$

Thus, options B and C are the answers.

hope this helps!
