Hello, I believe the answer you are looking for is:
- When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent.
Answer: -3
Step-by-step explanation: using the mathematical process
4-(4/4)-6=
4-1-6= -3
Answer:
Step-by-step explanation:
On this one you would eliminate the ones that are negative or that go into a negative. Which would be A,C, and E. The rest that are left are zero or positive. B for example is a zero because eventually there will be no candle. D would be the same in some way, the students will eventually leave the school. Finally F, the temperature would be increasing.
Answer - B,D,F

Answer:
<em>Multiply the bottom equation by -3/2 then add the equations.
</em>
<em>Multiply the top equation by-3. then add the equations
</em>
<em>
</em>
Step-by-step explanation:
Given the simultaneous equation
2x- 6y=6 ... 1
6x - 4y = 2 ... 2
To eliminate a variable, we have to make the coefficient of one of the variable to be the same.
Multiply equastion 1 by -3
-6x+18y= -18
6x - 4y = 2
Add the result:
-6x + 6x + 18y-4y = -18+2
18y-4y = -18+2
14y = -18
y = -9/7
Another way is to Multiply the bottom equation by -3/2 then add the equations.
Multiplying equation 2 by -3/2 will give;
6x(-3/2) - 4y(-3/2) = 2(-3/2)
-9x + 6y = -3
Add to equation 1;
2x- 6y=6
-9x + 2x + 0 = -3+6
-7x = 3
x = -3/7
Hence the correct two options are;
<em>Multiply the bottom equation by -3/2 then add the equations.
</em>
<em>Multiply the top equation by-3. then add the equations
</em>
