Hello,
{x=y-3
{x+3y=13;
{x=y-3
{y-3+3y=13;
{x=y-3
{4y=13+3;
{x=y-3
{4y=16;
{x=y-3
{y=16:4=4;
{x=4-3=1
{y=4;
{x=1
{y=4
the solution to the system of equations is (1,4)
Bye :-)
Density is the correct answer.
Answer:
-38.4
Step-by-step explanation:
Multiply both sides by 6 to get rid of the /6 then you would get z alone
1. 21,150
2. 2.5193
3. 27.98
4. 11,100
Answer:

Step-by-step explanation:
points on the line:- (-4,-5)&(6,4)
slope= 4+5/6+4= 9/10
y-4=9/10(x-6)
y=9x/10-54/10+4
y=9/10 x-7/5
