Answer:

f=-\frac{5}{3}

Step-by-step explanation:

-\frac{3}{4}f=\frac{5}{4}

(4)-\frac{3}{4}f=(4)\frac{5}{4}

-3f=5

\frac{-3f}{-3}=\frac{5}{-3}

f=-\frac{5}{3}

Pls I need help this
Citrus2011 [14]

Answer:

the third side is 4.

Step-by-step explanation:

Using  Pythagorean theorem of a^2 + b^2 = c^2 for right triangles, substitute

the numbers to show (\sqrt{65})^{2} + b^{2} = 9^{2} and solve for b. The square root and square cancel each other out, so you get 65 + b^{2} = 81.

Subtract 65 from both sides to get b^{2} = 16.

Then take the square root of both sides to get b = \sqrt{16} which equals 4.

Help please! What is the answer ?
kupik [55]

Answer:

x < -3 or x > 3

second answer choice

Step-by-step explanation:

 The symbol "∨" between p and q represents a disjunction and can be replaced with the word "or" to turn p ∨ q into p or q.

Plug in x < -3 in for p and x > 3 for q, and now you have:

x < -3 or x > 3

which is the same as the second answer choice.

So, the answer is x < -3 or x > 3, or the second answer choice.

I hope you find my answer helpful.
