Do you have any options of the equivalent expressions or is it just a plan question that you just asked?

For this case we have that by definition of power properties we have to:

a ^ {- b} = \frac {1} {a ^ b}

So, we can write 6 ^{- 3}as an equivalent expression:

6 ^ {-3} = \frac {1} {6 ^ 3}

We know that, by definition:

a ^ nrepresents the multiplication of "a" n times.

So, we have:

6 ^ 3 = 6 * 6 * 6\\6 ^ {- 3} = \frac {1} {6 ^ 3} = \frac {1} {6 * 6 * 6}

Answer:

6 ^ {- 3} = \frac {1} {6 ^ 3} = \frac {1} {6 * 6 * 6}

Need some help with this question!
Veronika [31]
1. solve for x in first to just find nterms of y

x=12-y
sub that for x in other one
first divide that one by 2 to make it easier
2x-y=18
2(12-y)-y=18
24-2y-y=18
24-3y=18
minus 24 both sides
-3y=-6
divide -3
y=2

D is answer




2.
find intersection of x+y=5 and -2x+3y=6
or easiers, just test the intersections
wait, they all intersect in the same place
this is super easy
pick ANY point that is in that reigon and see if it is true

A, if we pick lets say (5,5)
that is false for x+y<5
not A

B
pick (10,0)
false for first one
not B

C
pick (0,0)
true for first
false for 2nd
not C


D. pick (-10,0)
true for first
true for 2nd


answer is D


answer is D for both questions

Help with the step by step
Nataliya [291]

Step-by-step explanation:

First, distribute the -4 to the parenthesis:

24a-22=-4+24a

Add 22 to both sides:

24a-22+22=-4+22+24a

Simplify:

24a=18+24a

Subtract 24a from both sides:

24a-24a=18+24a-24a

Simplify:

0=18

hope this helps :)
