Answer:
Perpendicular: 4, Parallel: -1/4
Step-by-step explanation:
The slope of a line perpendicular to the given line is the opposite inverse of the slope to the line.
First write the equation of the line in slope-intercept form
-x-4y=7
-4y=x+7
y=-(1/4)x-7/4;
The slope to the line is -1/4; Now find the slope of the perpendicular line;
-(-1/4)^-1 = 4
4
The slope of a line parallel to a line is the same as the given slope;
when we calculated the given slope, it was -1/4
The slope of the line parallel to this line is also -1/4
-1/4
Answer:
64in2
Step-by-step explanation:
3+8+3=14
4+4=8
14x8=112
3x4=12
12x4=48
112-48=64
Answer:
Step-by-step explanation:
This relation (this group of points) is NOT a function. In order to be a function, every x-value (the first number in the pair) can only be paired up with one y-value (only one partner for the x)
In this relation, -6 is paired up with four different y-values (four different partners!)
If you plotted these points on a graph, you would see they are all lined up in a vertical line. If you have learned about the vertical line test, you will see that a vertical line goes through all four points. This set of points fails the vertical line test. To be a function, a vertical line can only touch the points one at a time.
To be a function, every x can only have one y partner.
R = square root of (A/pi)
0.375 is the answer hope this helps
