The slope, if you have a graph, is the angle the line is going down so look at this graph:
Answer: C
Step-by-step explanation:
We know that A and D will not be the correct answers. For A, it's only one 90 angles, but the questions said that has two angles. For D, it's two angles : 90 and 12, but in the question, 12 is the length, not the angle.
The correct answer is C.
The population would grow 1309 people (total 39,809)
Like fractions are fractions that have the same denominator. In option D, both denominators are 7. Therefore, they are like fractions.
