Answer:
±2sqrt(10) = x
Step-by-step explanation:
40 - x^2 = 0
Add x^2 to each side
40 - x^2+x^2 = x^2
40 = x^2
Take the square root of each side
sqrt(40) = sqrt(x^2)
±sqrt(40) = x
±sqrt(4) sqrt(10) = x
±2sqrt(10) = x
Answer:
50/100, simplified to 1/2
Step-by-step explanation:
50% means half of 1.
1/2=.5 which is half of 1.
1=100%
.5=50%
1/2=50%
Answer: C) I think?
Step-by-step explanation:
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

Remember that the denominator cannot be equal to zero
so
The value of x cannot be equal to x=-2
<em>Simplify the numerator</em>
----> by difference of squares
substitute

simplify

The domain is all real numbers except the value of x=-2
The y-intercept is the point (0,-6) ---> value of y when the value of x is equal to zero)
The x-intercept is the point (2,0) ---> value of x when the value of y is equal to zero)
therefore
The graph in the attached figure
