Answer:

D. x² - 3x + 1

Step-by-step explanation:

let

f(x) = x² + 1

g(x) = 3x

find:  f-g

f-g = f9x) - g(x)

    = x² + 1 - 3x

    = x² - 3x + 1

therefore, D is the answer

Tangent this equation: <img src="https://tex.z-dn.net/?f=63%28b-1%29%2B7%3D7%289b-8%29" id="TexFormula1" title="63(b-1)+7=7(9b-8
timurjin [86]

Answer: True for all <em>b</em>.

Step-by-step explanation: To tangent a equation, find if the variable is true.

1. Add 56 to both sides.

63b - 56 + 56 = 63b - 56 + 56 = 7

2. Simplify.

63b = 63b

3. Simplify again for your answer.

0 = 0

Hence, both sides are equal.

Let me know if you have any questions.

Z=Xm+n-p,solve for x
timama [110]

z=xm+n-p

We need to isolate x to one side I will do that on the left side so it looks cleaner, therefore I will first flip the equation.

xm+n-p=z

Now move the n and p to the right side

xm=z-n+p

x=(z-n+p)/m

Hope this helped, if you have any questions about this just comment and I will come answer.

Find the measure of the missing angles in the triangle below round your answer to the nearest degree
navik [9.2K]

Answer:

a. 40°

b. 21°

Step-by-step explanation:

a. Reference angle = θ

Opposite = 5

Adjacent = 6

Apply TOA:

Tan (\theta) = \frac{Opp}{Adj}

Tan (\theta) = \frac{5}{6}

\theta = Tan^{-1}(\frac{5}{6})

\theta = 40 (nearest degree)

b. Reference angle = x

Opposite = 5

Hypotenuse = 14

Apply SOH:

Sin (x) = \frac{Opp}{Hyp}

Sin (x) = \frac{5}{14}

x = Sin^{-1}(\frac{5}{14})

x = 21 (nearest degree)
