Answer:
Step-by-step explanation:
you do part a
Equation 1: 4x+y=2
Equation 2: 3x-3y=9
b
Divide equation 2 by 3
x-y=3
add y to both sides
x=3+y
Sbustitute this into equation 1
4(3+y)=2
12+4y+y=2
5y= -10
y= -2
Plug this into equation 1
4x-2=2
x=1
Part c.
Equation 1: 4x+y=2
Equation 2: 3x-3y=9
divide equation 2 by 3
x-y=3
add the two equations
(x-y)+(4x+y)=2+3
5x=5
x=1
Plug this into equation 1
4(1)+y=2
4+y=2
y= -2
For part a just create a table and graph it
Answer:
4
Step-by-step explanation:
5 + 3/1 + 1 =
8/2 =
4/1 =
4
This is because of slope formula which is x-x/y-y
Answer:
havarti? maybe 4 im sorry if its wrong
Step-by-step explanation:
You do 420/4 so therefore it would be 105 miles per square feet of the square.
