Y=-1/4x-5 and 2x+8y=56 determine if paralllel ,nethier or perpendicular

Dominik [7]

Answer:

Parallel

Step-by-step explanation:

In the slope-intercept form (y=mx +c), the coefficient of x tells us the slope of the line.

2x +8y= 56

Let's rewrite this equation into the slope-intercept form.

8y= -2x +56

Dividing both sides by 8:

$y= - \frac{2}{8} x + \frac{56}{8}$

$y = - \frac{1}{4} x + 7$

Slope= -¼

y= -¼x -5

Slope= -¼

Since both lines have the same slope, they are parallel to each other.

Vladimir [108]

Answer:

Step-by-step explanation:

the formula for radius is

$r=\sqrt{\frac{v}{\pi h } }$

so. 500 divided by pi times 10. then square root your final answer. cool. let's get started.

3.14*10 is 31.4, you can do that without thinking.

500/31.4=15.92

$\sqrt{}$ 15.92= 3.99, or just 4

the radius is four.
