What is the x-intercept of the following line y=-2x-1

Mathematics

the x intercept is where the line crosses the x axis or where y=0

so set y=0 and solve for x

0=-2x-1

solve for x

add 2x to both sides

2x=-1

divide by 2

x=-1/2

the x intercept is at x=-1/2, the point is (-1/2,0)

Find (f•g)(1) f(x)= x^2-1 g(x)=sqrt x

Anastaziya [24]

Answer:

Step-by-step explanation:

So we have the two functions:

$f(x)=x^2-1\text{ and } g(x)=\sqrt x$

And we want to find:

$(f\cdot g)(1)$

This is the same as:

$=f(1)\cdot g(1)$

So, let's find f(1) and g(1):

$f(1)=(1)^2-1$

Square:

$f(1)=1-1$

Subtract:

$f(1)=0$

$g(1)=\sqrt1$

Evaluate:

$g(1)=1$

So:

$(f\cdot g)(1)=f(1)\cdot g(1)=0\cdot1$

Multiply:

$=0$

So, our answer is 0.

And we're done!

Describe how to simplify the expression<br> 3^-6<br> 3^-4

Annette [7]

Answer:

For 3^-6 = 1/3^6 = 726 and for 3^-4 = 1/3^4 = 81

Step-by-step explanation:

ARE THE NUMBERS SEPARATED OR THEY ARE TO BE JOIN TOGETHER,IF THERE ARE SEPARATED THE SOLUTION IS GOING TO BE...

3^-6

using law of indices x^-a = 1/x^a

So 3^-6 = 1/3^6

Now find the power of 3^6

which is the same as 3×3×3×3×3×3 = 729

therefore 1/3^6 = 729

For 3^-4

using the above method

3^-4 is same as 1/3^4

which is equal to

finding the nominator

3×3×3×3 = 81

so the answer is 81
