Prove that f(x)=x+3/2 and g(x)=2x-3are inverse
goldfiish [28.3K]

Answer:

Proofs

Step-by-step explanation:

f(x) = x +  \frac{3}{2}

y = x +  \frac{3}{2}

x = y +  \frac{3}{2}

x -  \frac{3}{2}  = y

{f}^{ - 1} (x) = x -  \frac{3}{2}

They are not inverse because f^-1(x) = x - 3/2 is not the inverse to g(x) = 2x - 3.

How many triangles can you make with two side lengths of 6 inches that meet at a 50 degree angle.
Sonbull [250]
<h3>Answer: Exactly One Triangle</h3>

======================================================

Explanation:

Recall that by the SAS (side angle side) congruence theorem, if we know that two pairs of sides are the same length and the angles between them are also congruent, then we can conclude the triangles are congruent. This further means that we can only construct exactly one triangle with two side lengths of 6 inches, and they form a 50 degree angle between them. Applying transformations such as rotations, translations, or reflections will not change the triangle.

Side note: This triangle is isosceles because two sides are the same length. It is not equilateral because we would need to have all three angles to be 60 degrees.

Below are the solutions for a variable "x." State the solution that matches the graph below.
Aloiza [94]
We have a number line as indicated in the figure above. From this figure we know that the <em>x-values</em> <em>increase f</em><em>rom left to right</em>. So we need to write the solution<span> that matches the previous graph. Taking a look on the graph we see that x begins in -3 and closes in 8, that is, x <em>takes values from -3 to 8</em>. In a mathematical language this is given by the following statement: 

</span>x \in [-3,8]<span>
