-3x + 4y = 95 x + 5y = 38

7 0

We can solve this by elimination, in order to do this we need to multiply the bottom equation by three to cross out the X

(x+5y=38)3 3x+15y=114

-3x+4y=95
3x+15y=114

then add the two equations together and the X will cancel out

19y=209
----- -----
19 19

y=11

then plug that in into one of the equations

x+55=38
-55 -55

x= -17

your answer is (-17,11)

two stores sell the same computer for the same orginal price. store a advertises that the computer is 25% off the orginal price.

Gnoma [55]

That means that the discounts are the same
therfor 25% of original=180
multiply both sides by 4 or divide both sides by 0.25
original=720

the equation is
0.25 times original=180

and the original price is $720

Can someone please help and explain how to use the Pythagorean Theorem to prove a triangle is a right triangle.

marin [14]

Hi there!

For the Pythagorean Theorem, basically you just need to apply this formula: a^2 + b^2 = c^2

And then find the root of the hypotenuse.

For example,

15^2 + 8^2 = the hypotenuse^2

Which equals, 225 + 64 = 289

Square root of 289 = 17

Please mark me brainliest if this helps!

Have a wonderful day!
