Answer:
single solution : (4 ; 6)
Step-by-step explanation:
hello :
4x-y=10.....(1)
y=2x-2.....(2)
put the value for y in (1) :
4x-(2x-2)=10
4x-2x +2 = 10
2x=8
x=8/2 =4
but : y = 2x-2
so : y =2(4)-2=6
single solution : (4 ; 6)
The correct answer is the first choice

Answer:
x₂ = - 3
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to
m =
with (x₁, y₁ ) = (9, 9) and (x₂, y₂ ) = (x₂, - 1)
m = , that is
= ( cross- multiply )
5(x₂ - 9) = - 60 ( divide both sides by 5 )
x₂ - 9 = - 12 ( add 9 to both sides )
x₂ = - 3
