Answer:
B. Sometimes.
Step-by-step explanation:
We have been given a statement. We are asked to choose the option that is true for our given statement.
Statement:
If angles are supplementary, then one of the angles is an obtuse angle.
A. Always.
We know that two 90 degree angles are supplementary to each other. We know that a right triangle is not an obtuse angle, therefore, option A is not a correct choice.
B. Sometimes.
Since supplementary angles are not necessarily right angles always, one angle could be obtuse and one could be acute, therefore, option B is the correct choice.
C. Never.
We know that when an obtuse angle and an acute angle add up-to 180 degrees, they are supplementary, ex- .
Since 180 degrees is an obtuse angle, therefore, option C is not a correct choice.
How to solve 7-10: if a coordinate (x, y) is on the line, then f(x) = y.
7. Since x is 6, look at the graph, which shows that y (or f(x)) is 4. (look at picture)
8. Same thing as 7. you will see that f(x) is 15.
9. The other way around. since we know y = 2, looking at the graph shows us that x = 3.
10. Repeat process of 9. x = 10.
How to solve 11 + 12: slope formula (rise-over-run)
11. (14-4)/(12-6) = 10/6 = 5/3.
12. (16-14)/(18-12) = 2/6 = 1/3.
(If possible brainliest is appreciated :D)
