7 0

Answer:

2

Step-by-step explanation:

f(x) = 1 / x

f(1/2) = 1 / (1/2)

Reciprocal of 1/2 is 2, since you flip numerator and denominator:

f(1/2) = 2

What is the length of side x?
Vinil7 [7]

Answer:

x = 3

Step-by-step explanation:

In a 30-60-90 triangle the side between 60 and 90 degree angle is  a, the side between 30 and 90 degree angle is  a√3, and the hypotenuse is 2*a.

Given that the side that is supposed to be  a is currently √3, we know that the missing side x must be:

a√3    (We know that a, in this case, is √3, so substitute)

x = (√3) * (√3)

x = 3

Need help with this question asap pleasee
tresset_1 [31]

Answer:

The second choice is correct

Step-by-step explanation:

Here, we want to get the correct statement

As can be seen, while 2 is the angle at the circumference, 1 is the angle at the center

Mathematically, we know that angle at the center is two times the angle at the circumference

Thus,

m1 = 1/2 (m2)

or m2 = 2 * m1

Solve the system for x:<br> 6x - 5y = 8<br> 2x + 9y = 24
Gennadij [26K]

Answer:

x = 3

Step-by-step explanation:

\left \{ {{6x-5y=8} \atop {2x+9y=24}} \right.

I'm going to use the method of elimination by multiplying the second equation by -3:

\left \{ {{6x-5y=8} \atop {-6x-27y=-72}} \right.

Then I can eliminate x:

-32y = -64

To solve for y, I'd simply divide:

y = 2

Because I now have y = 2, I'll just plug in 2:

6x - 5(2) = 8

6x - 10 = 8

6x = 18

x = 3

Hopefully I helped :)
