Solve this system of linear equations. Separate
Tems11 [23]

Answer:

(-7,-4)

Step-by-step explanation:

There are 2 different ways to solve a system of equations and the one I'm going to show you will work for all systems.  To start we will solve one of the equations for either X or Y it doesn't matter which one so I will choose the second one.  Divide both sides by negative 4 and you will have the solved equation.  x=1+2y Now we know what x equals so we can plug "1+2y" into the other equation where we see an X and we will get -8(1+2y)=24-8y and since we only have one variable now we can solve to get what Y is.  The first step is distributing -8-16y=24-8y now lets put the Y's together on one side and the numbers together on the other -32=8y and just divide both sides by 8 to get the value of Y -4=y  Now that we have Y we can plug -4 into either equation as Y to get the value of X I will use the second equation.  -4x=-4-8(-4) and solve for X -4x=-4+32  -4x=28  x=-7 So now we have x and y and we can write it as out solution (-7, -4)

I hope this helps and please don't hesitate to ask if there is anything still unclear!

ABC is not an acute triangle what is the first step of indirectly proving this statement
dmitriy555 [2]

Answer:

Assume ΔABC is an acute triangle.

Step-by-step explanation:

Given the triangle ABC.

We have to tell the first step of indirect proving ΔABC is not an acute triangle.

An indirect proof, also known a proof by contradiction. When we use indirect proof method, we assume the opposite of our theory to be true and then by applying our assumed theory we contradict the given statement which proves our supposition is wrong. In other words, we assume our theory is false.

Hence, our first step is to

Assume ΔABC is an acute triangle.

Third option is correct.

50 POINTS !!<br><br><br> PLEASE HELP !! ILL GIVE BRAINLIEST TO THE RIGHT ANSWERS.
Artyom0805 [142]

Answer:

12

Step-by-step explanation:

Use the pythagorean theorem (a^2+b^2=c^2). A and b are the two legs of the triangle, and c is ALWAYS the hypotenuse. Plug in the values for a and c

a^2+b^2=c^2

5^2+b^2=13^2

25+b^2=169

b^2=144

b=12
