Answer:

They are neither.

Step-by-step explanation:

Graph both equations using either a graphing calculator or doing it by hand.

Observe the behaviors of the lines; Perpendicular lines bisect each other at a perfect 90 degree angle, while parallel lines never touch each other and are symmetrical.

Answer:

Neither

Step-by-step explanation:

We need to transform one of the equations into its slope-intercept form:

y + 2/5x = 8

Subtract 2/5x from both sides:

y = -2/5x + 8

y = -5/2x - 7

Graphing both lines, they do intersect at point (-7.14, 10.86), but they are not parallel, nor are they perpendicular from each other. By definition, perpendicular lines must appear to be perpendicular (that is, they intersect at a 90° angle).

Looking at the attached graph (where the purple line is y = -2/5x + 8), their lines do not form a 90° angle.

Therefore, the correct answer is neither.

Hey I really need help on this question please

Dmitry_Shevchenko [17]

A circle’s standard form of an equation is:
(x-h)^2 + (y-k)^2 = radius^2

Plug in h and k immediately because that is something you automatically know. H and k are derived from the center of the circle. The center of the circle is (h,k). Don’t get tripped up though, your center of a circle has negative coordinates. When you have two negatives, they become positive.

So now you have:
(x+4)^2 + (y-2)^2 = radius^2

So figure out what the radius is. Use the distance formula to find out. You have a change of 5 from -4 to 1 in x. You have a change of 2 from 2 to 4 in y. Distance formula has the distance as the square root of x distance squared and y distance squared. That would mean that the distance/radius is equal to the square root of (25 + 4). 5 squared is 25 while 2 squared is 4.

The radius of the circle is equal to the square root of (29). However, looking back at the circle equation the radius should be squared for the equation. Square root of 29 squared gets you 29.

Plug that in and you get:
(x+4)^2 + (y-2)^2 = 29
