Intersection means elements both have. Both sets have -1 but they have nothing else in common so the intersection is {-1}
Union means combining the sets so {-1, 1, 2, 3, 7} Note that I only wrote 1 twice. No duplicates allowed!
Answer:
Rewriting the expression 
with a rational exponent as a radical expression we get ![\mathbf{\sqrt[9]{3} }](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Csqrt%5B9%5D%7B3%7D%20%7D)
Step-by-step explanation:
We need to rewrite the expression with a rational exponent as a radical expression.
The expression given is:
First we will simply the expression using exponent rule 
As we know 2 and 18 are both divisible by 2, we can write
Now we know that ![a^\frac{1}{9}=\sqrt[9]{a}](https://tex.z-dn.net/?f=a%5E%5Cfrac%7B1%7D%7B9%7D%3D%5Csqrt%5B9%5D%7Ba%7D)
Using this we get
![=\sqrt[9]{3}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B9%5D%7B3%7D)
So, rewriting the expression with a rational exponent as a radical expression we get
Answer:
6,000,000.005
Step-by-step explanation:
The correct answer in [standard form] is 6,500,000
one million= 1,000,000
six million= 6,000,000
one thousandth= .001
five thousandth= .005
6,000,000.005
Word Form: Six million and five thousandth
Answer:x = 12
Step-by-step explanation:
The equation One-half x + 3 = two-thirds x + 1 is expressed as
x/2 + 3 = 2x/3 + 1
The first step would be to to find the lowest common multiple of the left hand side of the equation and the right hand side of the equation and multiply the left hand side of the equation and the right hand side of the equation by the lowest common multiple. The lowest common multiple is 6. Therefore,
x/2 × 6 + 3 × 6 = 2x/3 × 6 + 1 × 6
3x + 18 = 4x + 6
4x + 6 = 3x + 18
Subtracting 3x and 6 from the left hand side of the equation and the right hand side of the equation, it becomes
4x - 3x + 6 - 6 = 3x - 3x + 18 - 6
x = 12
Answer:
The answer is y= -4x-14
Step-by-step explanation:
y= 1/4x - 7 (-2, -6)
y=1/4x - 7
y=mx+b
y=-4/1x+b
-6=-4(-2)+b
-6=8+b
-8 -8
-14=b
