First of all, you should know/notice that
You should also know how negative exponents work:
So, if you wanted
the answer would be x=3, but since you want 125 to be at the denominator, the answer is x=-3:
The answer is -1/16 or -0.0625, do you need to see work?
Answer:
9 IS THE ANSWER
Step-by-step explanation:
3*3=9
Answer:
10
Step-by-step explanation:
If you were to use the substitution method to solve the following system, we need to write one of the equation to an <span>expression equivalent to y. Let us say the second equation, we write it as follows:
</span><span>6x – 3y = –3
-3y = -6x - 3
y = 2x + 1
We substitute the equation to the first given equation as follows:
</span><span>2x – 5y = –3
</span>2x – 5(2x + 1) = –3
2x - 10x - 5 = -3
-8x = 2
x = -1/4
y = 2(-1/4) + 1 = 1/2
