Factor out the common term 2
2(2x + y) = -2
Divide both sides by 2
2x + y = -1
Subtract 2x from both sides
<u>y = -1 - 2x</u>

Answer:
6384
Step-by-step explanation:
14*19*6*4= 6384
area means multiply.
Answer:
The red one/bottom one. x>-8
Step-by-step explanation:
Subtract 7 giving you 16. Divide by negative 2 which gives you -8, but since your dividing by a negative you have to flip the sign. The Answer is x>-8. The Sign points which way you have to shade, the answer is which point you shade at, and the opened circle means that it is NOT equal to that answer but it is bigger. Closed circle if it is equal to. ;)
Answer:
Geometry! Nice!
Step-by-step explanation:
This is very simple. In a nutshell, base angles in a isosceles triangle are equal.
Thus:

Time to solve!

Now that we have found the x-value, all we need to do is input it back in for one of the angles.

Moving on, there is a rule in geometry that states that the sum of all angles in triangles is equal to 180, no matter what.
All that has to be done is just multiply 50 by 2, add y in for our third angle, and set that equal to 180.

After all that, the measure of the third angle in the triangle is 80 degrees (make sure to include degrees in your answer).
Stay safe, and wear a mask!
