3 yards and 16 inches=124 in
Answer:
A=124 in
D=124 in
E=124 in
A function associates a value from a set (domain) one and only one value from another set. IE, from the same x value you can have only one y. So pick a ruler and scan each graph parallel to the Y axis. If you touch the blue line in two points, that's not a function.
Answer:
= 16
Step-by-step explanation:
1/5 of 20 = 4
so,
4/5 of 20 = 16
Check the picture below.
to graph a LINEar equation, since it's just a line and for a line all you need is two points and draw away, simply pick two random "x" values to get the "y" values and plot those two points.
for y = -x + 2
if we choose x = 0, then y = -0 + 2 => y = 2, that gives us the point (0 , 2)
if we choose x = 2, then y = -2 + 2 => y = 0, that gives us the point (2 , 0)
graph it and we get the blue line.
for the 2nd equation
![y = \cfrac{2}{3}x-1\hspace{5em}\underline{x=3}~\hfill y=\cfrac{2}{3}(3)-1\implies y=2-1\implies y=1 \\\\\\ ~\hfill \boxed{(3~~,~~1)} \\\\\\ ~\hspace{9.5em}\underline{x=0}~\hfill y=\cfrac{2}{3}(0)-1\implies y=-1 \\\\\\ ~\hfill \boxed{(0~~,~~-1)}](https://tex.z-dn.net/?f=y%20%3D%20%5Ccfrac%7B2%7D%7B3%7Dx-1%5Chspace%7B5em%7D%5Cunderline%7Bx%3D3%7D~%5Chfill%20y%3D%5Ccfrac%7B2%7D%7B3%7D%283%29-1%5Cimplies%20y%3D2-1%5Cimplies%20y%3D1%20%5C%5C%5C%5C%5C%5C%20~%5Chfill%20%5Cboxed%7B%283~~%2C~~1%29%7D%20%5C%5C%5C%5C%5C%5C%20~%5Chspace%7B9.5em%7D%5Cunderline%7Bx%3D0%7D~%5Chfill%20y%3D%5Ccfrac%7B2%7D%7B3%7D%280%29-1%5Cimplies%20y%3D-1%20%5C%5C%5C%5C%5C%5C%20~%5Chfill%20%5Cboxed%7B%280~~%2C~~-1%29%7D)
graph it and we get the red line
notice, those points are in those lines, and to graph a LINE, all you need is two points.
