Write the values that make the denominators zero. then solve the equation?
Olin [163]

Answer:

  denominators are zero for x=1

  there is no solution

Step-by-step explanation:

We suspect your equation is supposed to be ...

  10/(5x -5) +1/5 = 2/(x -1) . . . . . parentheses are required on denominators

The denominators will be zero for x=1.

This version of the equation has no solution. It simplifies to ...

  2/(x-1) + 1/5 = 2/(x -1)

  1/5 = 0 . . . . . subtract 2/(x-1) from both sides

There is no value of x that will make this equation true.

_____

<em>Alternative interpretation</em>

The way your equation is written, it must be interpreted according to the order of operations to be ...

  (10/5)x -5 +1/5 = (2/x) -1 . . . . x=0 makes the denominator zero

  2x -3.8 = 2/x

  2x^2 -3.8x = 2 . . . . multiply by x

  2(x^2 -1.9x +.95^2) = 2 +2(0.95^2)

  (x -0.95)^2 = 1.9025

  x = 0.95 ± √1.9025 ≈ {-0.4293, 2.3293}

Those 2 questions I need help with . find sec θ and tanθ
Zielflug [23.3K]

STEP - BY - STEP EXPLANATION

What to find?

The the value of secθ.

Given:

(4, 3)

⇒(x, y) = (4, 3)

Step 1

Draw a sketch.

Step 2

Substitute the values into the trig. ratio formula below.

tan\theta=\frac{opposite}{adjacent}

From the sketch above, opposite = 3 and adjacent = 4

tan\theta=\frac{3}{4}

Step 3

Find the value of the hypotenuse side using Pythagoras theorem.

let h be the hypotenuse side.

\begin{gathered} h^2=4^2+3^2 \\  \\ =16+9 \\  \\ =25 \\  \\ h=5 \end{gathered}

Hence, hypotenuse = 5

Step 4

Substitute the values into the formula below:

\begin{gathered} cos\theta=\frac{adjacent}{hypotenuse} \\  \\ =\frac{4}{5} \end{gathered}

But,

sec\theta=\frac{1}{cos\theta}=\frac{1}{\frac{4}{5}}=\frac{5}{4}

ANSWER

secθ= 5/4

tanθ=3/4
