Can you always put two triangle together to make a rectangle? Explain why or why not.

1 answer:

no, since a rectangle requires 90-degree corners, and every angle inside an equilateral triangle is 60-degrees. The only multiple of 90 that you can make is 180-degrees (or any multiple of it).

Y= 5x + 13 <br> and<br> y= x + 45

arsen [322]

Answer:

x=8 and y=53

Step-by-step explanation:

Given function:

y=5x+13
y=x+45

Find x:

the two equation, the x and are breaked apart..
so find a number that they can both equal to together and has the same y.
multiply by 8..
$5$ · $8=40$

combine the terms for x and 13
$40+13=53$

since x is 8 then if we add 8 with 45 it should be 53...
$8+45=53$

y is:

this means that y=53.

Therefore, x=8 and y=53..

Foci of ellipse of 3x2 + y2 =9

Oksi-84 [34.3K]

Answer:

x=√-1/3 y^2 +3 or x=-√-1/3 y^2 +3

Step-by-step explanation:

Let's solve for x.

3x2+y2=9

Step 1: Add -y^2 to both sides.

3x2+y2+−y2=9+−y2

3x2=−y2+9

Step 2: Divide both sides by 3.

3x^2/3= -y^2+9/3

x^2=-1/3 y^2 +3

x=√-1/3 y^2 +3 or x=-√-1/3 y^2 +3

Hope it helped!
