For the linear system :

r+t = 20 and 5(r+t) = 150

If you sub in the first equation into the second, you will get: 100 = 150, which is incorrect

It means the system does NOT have solutions.

Answer will be the last choice

Explain how proving to triangles congruent can help prove parts of the triangle congruent.
nydimaria [60]

Answer:

CPCTC - Corresponding Parts of Congruent Triangles are Congruent

Step-by-step explanation:

When two triangles are congruent, this means they have the same shape and the same size. To have the same shape, each angle must be congruent. To have the same size, each side length must be congruent. When you know two triangles are congruent you can say each corresponding part of congruent triangles is congruent. This is known as CPCTC.

If {4x-3y=17 and 2x-5y=-11 then y=?
anyanavicka [17]
You need to solve this "system of linear equations."  In other words, find a point (x,y) that satisfies both 4x-3y=17 and 2x-5y=-11.

Try solution by elimination.  Multiply the 2nd equation by -2 to obtain -4x+5y=22.  Add this result to the 1st equation.  I'd suggest you write this out to see what is happening.  

 4x-3y=17

-4x+10y=22
----------------
        7y=39.  Solving for y, we get y=39/7 (a rather awkward fraction).

Now find x.  To do this, substitute 39/7 for y in either of the given equations.  Solve the resulting equation for x.

Write your solution in the form (x, y):  ( ? , 39/7).

Determine whether the point (2, 0) is a solution to the system of equations. Explain
vodomira [7]

Answer:

(2,0) IS NOT a solution to the system of equations because at that point the lines do not intersect. At (2,0) there's not even a line
