Let's find f(x) = 2, which is essentially what the problem is asking, what x corresponds to an output of 2.


Let's solve below:

f(x) = 2

  • Setting up what we know

23x + 4 = 2

  • Substituting in 23x + 4 for f(x) (I'm not sure if this is the correct expression for f(x) due to formatting issues)

23x = -2

  • Subtract 4 from both sides to make a step to isolate x (what we are trying to find)

x = - \frac{2}{23}

  • Divide both sides of the equation by 23 to isolate x

Thus the input is \boxed{x = - \frac{2}{23}}.

Question 1(Multiple Choice Worth 5 points)
Nadusha1986 [10]

Answer: arc\ length =13.19cm

Step-by-step explanation:

You need to use the following formula:

arc\ length=r\theta

Where "r" is the radius and \theta is is the central angle of the arc in radians.

Assuming that that the angle \frac{3\pi }{5} is the central angle of the arc, and knowing that the radius is 7 centimeters, you can substitute values into the formula.

Therefore, you get:

arc\ length=r\theta\\\\arc\ length= (7cm)(\frac{3\pi}{5})}\\\\arc\ length =13.19cm

To solve this problem and calculate the security's equilibrium rate of return, you should sum<span> the security's default risk premium (2.00%),</span> the inflation risk premium (1.75%), the real risk-free rate (3.50%), the security's liquidity risk<span> premium (0.25%) </span><span>and the maturity risk premium (0.85%). So, you have:

Find the value of that makes m ll n.
Alja [10]

Answer: x = 108

Step-by-step explanation: In this problem, we're given a diagram and

we're asked to find the value of x that would make m ll n.

We can see that the angles that are marked in the diagram

are same-side interior angles since they lie on the same side

of the transversal and they lie on the interior of lines m and n.

Therefore, in order for line m to be parallel to line n,

these angles must be supplementary.

In other words, they must add to 180 degrees.

So we can setup the equation x + 72 = 180.

Subtracting 72 from both sides gives us x = 108.

So the value of x that would make line m ll n is 108.
