Answer:
1
Step-by-step explanation:
(3/2) + 2M = (7/2)
(7/2) - (3/2) = 2M
2 = 2M
M = 1
Answer:
Domain = (-5,1,3)
Range = ( -4,-2,0,2,4)
This is not a function
Step-by-step explanation:
Domain = (-5,1,3)
Range = ( -4,-2,0,2,4)
Since one x value gives two points for y
this is not a function
<h3>que cada diarepe s it t </h3>
First you want to know what y or x is i chose y for this on
so the equation i'm going to use is -2x-5y=3
i want to solve for y
-2x-5y=3
+2x +2x
-5y=2x+3
/-5 /-5 /-5
y=-2/5x+-3/5
Now that i solved for y we substitute our answer into the next equation to solve for x like this:
3x+8y=-6
3x+8(-2/5x+-3/5)=-6
3x+ -3.2x+-4.8=-6
-0.2x+-4.8=-6
+4.8 +4.8
-0.2x=-1.2
/-0.2 /-0.2
x=6
After you know what x is you substitute it in for any of the equations that we started with. I picked 3x+8y=-6 to find y.
3x+8y=-6
3*6+8y=-6
18+8y=-6
-18 -18
8y=-24
/8 /8
y=-3
Since we know what x and y are we substitute it with any of the equations that we started with. i picked -2x-5y=3
-2*6-5*-3=3
-12- -15=3
3=3
so our solution (6,-3) works
