Answer:
Step-by-step explanation:
1) 2x -y = 1 -------1
3x - y = -6 ------2
Subtract eqn 2 from eqn 1
-x = 1--6 = 7
x = -7
Put x= -7 in eqn 1
2*-7-y = 1
-14-y = 1
- y = 15
y = -15
2) 4x +2y = 10------1
y = 4x + 2--------2
Put eqn 2 in eqn 1
4x + 2 ( 4x+ 2) = 10
4x + 8x + 4 = 10
12x = 6
x = 6/12 = 1/2
Put x = 1/2 in eqn 2
y = 4* 1/2 + 2= 2 + 2
= 4
3) 6x - y = 2------1
y = 3x + 4---------2
Put eqn 2 in eqn 1
6x - (3x +4) = 2
6x - 3x - 4 = 2
3x = 6
x = 2
y = 3*2 + 4 = 6 + 4
= 10
Answer:
D) -5/3
Step-by-step explanation:
(Points on the graph): (6, 10) and (12, 0)
Slope:
m=(y2-y1)/(x2-x1)
m=(0-10)/(12-6)
m=(-10)/6
m = -5/3
Answer:
11.327
Step-by-step explanation:
Answer:
6, 12, 18,
Step-by-step explanation:
u didn't said the numbers but here is the explanation
6÷2=3
6÷3=2
12÷3=4
12÷2=6
18÷2=9
18÷3=6
It means that 15 times another number equals to your equation.
