Answer:

The answer is √5 .

Step-by-step explanation:

You have to rationalize the fraction in order to get rid of surd in the denorminator by multiplying √3 to both numerator amd denorminator :

\frac{ \sqrt{15} }{ \sqrt{3} }

=  \frac{ \sqrt{15} }{ \sqrt{3} }  \times  \frac{ \sqrt{3} }{ \sqrt{3} }

=  \frac{ \sqrt{15} \times  \sqrt{3}  }{ \sqrt{3}  \times  \sqrt{3} }

=  \frac{ \sqrt{45} }{3}

=  \frac{ \sqrt{9 \times 5} }{3}

=  \frac{3 \sqrt{5} }{3}

=  \sqrt{5}

If f(x)= 3x+1 is reflect across the y-axis; what would the slope &amp; y-intercept be? *
Elden [556K]

Answer: f(x) = -3x + 1

So the slope is -3 and the y-intercept is 1

Step-by-step explanation:

This is because it’s across the y-axis so the y-intercept doesn’t change. Because it’s a reflection the slope just becomes the opposite of what it originally was, so in this case it will be -3

1,-2,3,-4,5... <br><br> what’s the next two numbers in the pattern?
MrMuchimi

Answer:

The two numbers following 1,-2,3,-4,5...  are -6 and 7.

Step-by-step explanation:

index:   1   2   3   4   5 ....

value:    1  -2  3  -4   5

Let the index be n.  Then the first term is a(1), the secon is a(2), and so on.

a(2) = 2*(-1)^(2-1) = 2*(-1) = -2 (correct)

a(3) = 3*(-1)^(3-1)   =  3*(-1)^2 = 3 (correct)

a(4) = 4*(-1)^(4-1)    = 4*(-1)^3 = -4 (correct)

So the general formula for a(n)  is:    a(n)=n(-1)^(n-1)

Thus,

a(5) = 5(-1)^4 = 5

a(6) = 6(-1)^5 = -6

a(7) = 7(-1)^6 = 7

The "next two numbers in the pattern" are -6 and 7.  The first 7 numbers are

1,-2,3,-4,5, -6, 7
