Answer:
B. 36°
Step-by-step explanation:
According to the sum of angles of triangles, in a triangle, the three interior angles always add to 180°: A + B + C = 180°.
We are given two angles, so we must solve for the third so their sum is 180.
65 +79 + x = 180. Add.
144 + x = 180. Subtract 144 from both sides.
x = 36.
Therefore, the missing angle is 36°.

Answer: the solution to the inequality is -3 < x < 4. Graphically, this should be (2)
Step-by-step explanation:Note that x^2 - x - 12 factors to (x - 4)(x + 3) < 0, so we have:
(x - 4)(x + 3) < 0.The only way for (x - 4)(x + 3) to be negative is if x - 4 and x + 3 have opposite signs. This only occurs when:
(i) x - 4 < 0 AND x + 3 > 0
==> x < 4 AND x > -3; both occur when -3 < x < 4.
(ii) x - 4 > 0 and x + 3 < 0, which cannot happen at the same time.

Get x by itself.
Answer:
To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect. The two lines intersect in (-3, -4) which is the solution to this system of equations. I hope this helped!
