??
Step-by-step explanation:
Answer:
It has one solution (1,0)
Step-by-step explanation:
y = -2x + 2
y = 4x -4
Substitute the y's
4x - 4 = -2x + 2
Let's move the variables to one side
4x - 4 = -2x + 2
+2x +2x
6x - 4 = 2
Lets move the constant to the other side
6x - 4 = 2
+4 +4
6x = 6
Divide both sides by 6
6x/6 = 6/6
x = 1
Let go back to y = -2x + 2
Substitute the x with 1
y = -2(1) + 2
y = -2 + 2
y = 0
Answer:
x ∈ (-oo ; 3)
Step-by-step explanation:
4x - 7 < 5
4x < 5 + 7
4x < 12
x < 12 : 4
x < 3
x ∈ (-oo ; 3)
A) S = 2410
b) S = 2410÷4= 602.5
I hope you know
180-132+x-6x+12=0
48+x-6x+12=0
48-5x+12=0
60-5x=0
-5x=-60
x=12
