Answer:
(-3, 9)
Step-by-step explanation:
If a point was reflected across the y-axis, then the y-coordinate would change signs (from negative to positive or from positive to negative). Using this, we could find the original point by changing the sign of the y-coordinate. As you may already see, this is really just reflecting the point across the y-axis again. By doing this, you get the point (-3, 9).
The point would be (-3, 9).
I hope this helps. :)
Answer: 71 people per year
Step-by-step explanation:
8210 - 7500 = 710
710 ÷ 10 = 71.
Rate of growth in people per year for those 10 years = 71 people per year.
3. 5mn ( 2m + 6n + 1 )
4. 4a^3b^2c ( 18a^2b - 8c )
5. (X-15)(X+15)
6. -4(y-4.5)(y+4.5)
8. 2X(X-10)(X+10)
i am not sure if no. 8 is right
Answer: D.The domain and range of the function are the same.
Step-by-step explanation: Given function f(x)=-√-x.
The given function is a square root function and we have minus sign in front of x inside square root.
A square root always defined for positive values or 0.
In order to get a positive number or 0 inside square root, let us solve the inequality:
On dividing both sides by -1, the inequality sign would get flip and we get
<h3>Domain:
</h3>
We can see that we have a negative sign in front of square root. So, the value of f(x) would be always a negative number or 0.
<h3>Therefore, range would also be :
.</h3><h3>Therefore, correct option is D option.</h3>
Redville = r
Greenboro = 12r
Total of the two towns = 65
Now we can set up our equation.
r + 12r = 65
13r = 65
13r/13 = 65/13
r = 5
Redville gets 5 inches
