<span>y = -3x + 4
x + 1/3y = 4/3
Substitute the first expression into the second equation for y:
</span>x + 1/3(-3x + 4) = 4/3
x - x + 4/3 = 4/3
4/3 = 4/3
Answer;
All real numbers are solutions.
Hope this helps.
Answer:
a=42°
b=138°
Step-by-step explanation:
the sum of angles on a triangle is 180°
so
18+120+a=180
138+a=180
a=180-138
a=42
a+b=180 because a ans b are linear pair of angles.
Definiton:A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
a=42 from before
it means that b=180-42=138
