What a coincidence that I just did this in my math class today. A function is a relation in which no 2 different ordered pairs have the same first coordinate. They are allowed to have the same second coordinate. So the third option is correct.
Answer:
x = 5
m∡B = 66°
Step-by-step explanation:
these two angles are same-side interior angles, which are supplementary
8x + 74 + 2x + 56 = 180
10x + 130 = 180
10x = 50
x = 5
m∡B = 2(5) + 56 = 66°
Answer:
C 4.5 the two triangles in the diagram are similar.
Step-by-step explanation:
Since, the two triangles in the diagram are similar.
Therefore,
The percentage for both the cases would be 100% and 35% respectively
x * 5 - 17 = -8
Simplify the equation.
5x - 17 = -8
Add 17 to both sides of the equation.
5x = 9
Divide both sides by 5.
x = 1.8
