For the following system, use the second equation to make a substitution for y in the first equation. 3x + y = 1 y + 4 = 5x What

Debora [2.8K]

Answer:

The answer is A.

Step-by-step explanation:

So we have the two equations:

$3x+y=1\\y+4=5x$

To make a substitution of the second equation into the first equation, we need to isolate the <em>y </em>variable in the second equation. Thus:

$y+4=5x\\y=5x-4$

Now, we can substitute this into the first equation. Therefore:

$3x+y=1\\3x+(5x-4)=1\\3x+5x-4=1$

How to solve this system of equal: x+y+z=1;x^2+y^2+z^2=1

swat32

There are infinitely many solutions.

Algebraically, we can eliminate $z$ and try to solve for $x,y$ :

$x+y+z=1\implies z=1-x-y$

Then

$x^2+y^2+(1-x-y)^2=1$

$\implies x^2+y^2+1-2x+x^2-2y+y^2+2xy=1$

$\implies x^2-x+y^2-y+xy=0$

which is the equation of an ellipse.

kramer

Answer:

A=50 B=40 C=90

Step-by-step explanation:

B is a right angle so its automatically 90 degrees since A=50 and a triangle has to be 180 degrees 90+50= 140, 180-140=40.
