Answer:
Infinitely many.
Step-by-step explanation:
3x + 2y = 4
-6x - 4y = -8
Note that the second equation is obtained from the first by multiplying the first one by -2. Thus the graph of the 2 equations is the same line and there are infinitely many solutions.
taking 2 to the other side ⇒
= 5 x 2
3x=10
taking 3 to the other side ⇒ x =
x = 3.34
Answer:
g
Step-by-step explanation:
Answer:
Neither parallel nor perpendicular
Step-by-step explanation:
To tell whether two lines are parallel or perpendicular, look at their slopes.
Parallel lines will have the same slope. This isn't the case since the first line has a slope of 1 and the second has a slope of -1.
Perpendicular line have slopes that are negative inverses of the other. This also isn't the case for these two lines. Although the slopes have opposite signs, the numbers aren't inverses.
The two lines are neither parallel nor perpendicular.
Answer:
40,000
Step-by-step explanation:
You want to start with the exponent and then multiply afterward in both of the equations.
8 x 10^-2:
10^-2 = 0.01
0.01 x 8 = 0.08
2 x 10^-6:
10^-6 = 0.000001
0.000001 x 2 = 0.000002
Obviously, you can see the relationship between 8 and 2 in the division. Now, you just divide 0.08 by 0.000002 and you get 40,000.
