Hi there!  

»»————- ★ ————-««

I believe your answer is:  

\boxed{x=9}

»»————- ★ ————-««  

Here’s why:  

  • We would have to use inverse operations to solve the equation.

⸻⸻⸻⸻

\boxed{\text{Solving the Equation for 'x':}}\\\\-9x+1=-80\\---------\\\rightarrow -9x+1-1=-80-1\\\\\rightarrow -9x=-81\\\\\rightarrow\frac{-9x=-81}{-9}\\\\\rightarrow \boxed{x=9}

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.

Answer:

x = 9

Step-by-step explanation:

first, you would subtract 1 from 80 and get -9x = -81 then you can just divide -81 by -9 or 9 from 81, either way, you'll have x = 9

URGENT!<br> How do you I know if there's 2 possible triangles for an ambiguous case?
ivolga24 [154]

Answer: ?Once you find the value of your angle, subtract it from 180° to find the possible second angle. Add the new angle to the original angle. If their sum is less than 180°, you have two valid answers. If the sum is over 180°, then the second angle is not valid??????

HELP MEEEEEEEEEEE PLZZZZZZ I NEEEEED ANSWER RIGHT NOWWWWW
lara31 [8.8K]

Answer:

Therefore the measure of∠ A is 60.07.

Step-by-step explanation:

Given:

In Right Angle Triangle ABC

∠ B = 90°

BC = 13   ....Side opposite to angle A

AC = 15  .... Hypotenuse

To Find:

m∠A = ?

Solution:

In Right Angle Triangle ABC ,Sine Identity,

\sin A = \dfrac{\textrm{side opposite to angle A}}{Hypotenuse}\\

Substituting the values we get

\sin A = \dfrac{BC}{AC}=\dfrac{13}{15}=0.8666\\\\A=\sin^{-1}(0.8666)=60.065\\\\m\angle A=60.07\°

Therefore the measure of∠ A is 60.07

Dose the infinite geometric series diverge or converge? explain 3+9+27+81
tamaranim1 [39]
The terms will be 3, 9, 27, 81 and so on.

notice, to get the next term, we simply multiply the current one by 3, namely the "common ratio" r = 3.

to make it plain and short, if 0 < | r | < 1, then the series sum will diverge, namely is approaching an explicit value, instead of just going on and on to infinity.

0 < | r | < 1, namely, if the common ratio is between 0 and 1, well a fraction, either negative or positive, only then the serie sum will diverge.  In this case is 3 and 3 is definitely not a fraction in that range.
