Answer:

X=18.5

Y=37

Step-by-step explanation:

DOB=16° because it's a vertical pair. Because COF is 90°, that means 4x+16 is also 90.

4x+16=90, subtract 16

4x=74, divide by 4

x=18.5

Because EOA is 90°, and you know DOB is 16°, you can set 2y+16 equal to 90 as well.

2y+16=90, subtract 16

2y=74, divide by 2

y=37

Answer:

x=18.5\° and y=37\°

Step-by-step explanation:

Givens:

  • AB and CD are straight lines. Which means all angles on those lines must sum 180°.

\angle AEO = 90\°, \angle AOC = 16\°, \angle FOB = 4x,  \angle COF = 90\°, by given.

Now, 16\° + 90\° + 2y=180\°, by defintion of straight lines and supplementary angles.

Then, we solve for y

2y=180-106\\y=\frac{74}{2}\\ y=37\°

Now,

\angle BOD = \angle AOC = 16\°, by vertical angles definiton.

Then,

90\°+4x+16\°=180\°, by defintion of straight lines and supplementary angles.

Then, we solve for x

4x=180-106\\x=\frac{74}{4} =18.5\°

Therefore, the solutions are x=18.5\° and y=37\°

Suppose h(x)=3x-2 and j(x) = ax +b. Find a relationship between a and b such that h(j(x)) = j(h(x))
sergejj [24]

Answer:

\displaystyle a = \frac{1}{3} \text{ and } b = \frac{2}{3}

Step-by-step explanation:

We can use the definition of inverse functions. Recall that if two functions, <em>f</em> and <em>g</em> are inverses, then:

\displaystyle f(g(x)) = g(f(x)) = x

So, we can let <em>j</em> be the inverse function of <em>h</em>.

Function <em>h</em> is given by:

\displaystyle h(x) = y = 3x-2

Find its inverse. Flip variables:

x = 3y - 2

Solve for <em>y. </em>Add:

\displaystyle x + 2 = 3y

Hence:

\displaystyle h^{-1}(x) = j(x) = \frac{x+2}{3} = \frac{1}{3} x + \frac{2}{3}

Therefore, <em>a</em> = 1/3 and <em>b</em> = 2/3.

We can verify our solution:

\displaystyle \begin{aligned} h(j(x)) &= h\left( \frac{1}{3} x + \frac{2}{3}\right) \\ \\ &= 3\left(\frac{1}{3}x + \frac{2}{3}\right) -2 \\ \\ &= (x + 2) -2 \\ \\ &= x \end{aligned}

And:

\displaystyle \begin{aligned} j(h(x)) &= j\left(3x-2\right) \\ \\ &= \frac{1}{3}\left( 3x-2\right)+\frac{2}{3} \\ \\ &=\left( x- \frac{2}{3}\right) + \frac{2}{3} \\ \\ &= x  \stackrel{\checkmark}{=} x\end{aligned}
