X - 4y = 2.....multiply by -3
3x + 2y = 6
-------------
-3x + 12y = -6 (result of multiplying by -3)
3x + 2y = 6
------------add
14y = 0
y = 0
3x + 2y = 6
3x + 2(0) = 6
3x = 6
x = 6/3
x = 2
solution is (2,0).....so the graph that has the two lines intersecting (crossing) at (2,0) is gonna be ur graph
Do 224x8
This would equal 1792.
He traveled 1792 miles.
I hope you understand. :-)
Answer:
|−∣=7
Explanation:
∣−∣
= |(-2-5)|
= |-2-5|
= | -7|=7
Exponent of a number says how many times.
2³
The 2 is the base number, while the little 3 is the exponent.
2³ = 2 x 2 x 2 = 8
Basically, you would just have to do two, three times.
Very time when you get the hang of it !!
Answer:
f(2) =8
Step-by-step explanation:
f(2) Is when n=2
f(2) = -5 *f(2-1) -7
f(2) = -5 *f(1) -7
We know that f(1) = -3
f(2) = -5 *-3 -7
= 15 -7
= 8
