Answer:

4x + 9 ≥ 0

Step-by-step explanation:

The inside of the square root, the radicand, cannot be negative.

It can only be zero or positive.

Zero or positive is also described as being greater than or equal to 0.

Set the radicand to be greater than or equal to zero.

Determine the intercepts of the line: -3x-4=-5y-8
Nina [5.8K]

The x-intercept is 4/3 and y-intercept is -4/5

Step-by-step explanation:

Given equation of line is:

-3x-4=-5y-8

To find the x-intercept, we put y=0 in the equation

-3x-4=-5(0)-8\\-3x-4=0-8\\-3x-4=-8\\-3x=-8+4\\-3x=-4

Dividing both sides by -3

\frac{-3x}{3} = \frac{-4}{-3}\\x = \frac{4}{3}

To find the y intercept, we put x=0

-3(0)-4=-5y-8\\-4 = -5y-8\\-5y-8 = -4\\-5y = -4+8\\-5y = 4\\

Dividing both sides by -5

\frac{-5y}{-5} = \frac{4}{-5}\\y = -\frac{4}{5}

Hence,

The x-intercept is 4/3 and y-intercept is -4/5
