An advertising agency increased their fees to an $80 setup fee plus $4 for every advertisement. Write a rule for the new fee. Write ordered pairs for the fees for 10, 20, 30, and 40 advertisements. y = 80 + 4x (10, 120), (20, 160), (30, 200), (40, 240) y = 80 + 4x (120, 10), (160, 20), (200, 30), (240, 40) y = 80 + 4 + x (120, 10), (160, 20), (200, 30), (240, 40) y = 80 + 4 + x (10, 120), (20, 160), (30, 200), (40, 240)

When using the linear combination metho e linear combination method to solve a system of linear equations, the four options are:

]supplementary angles are two angles that add up to . • complementary angles are two angles that add up to degrees. • adjacent angles share a and a • congruent angles have the measure. • an triangle has one angle that is greater than 90 degrees. • a triangle with angles 45°, 45°, and 90° would be a triangle

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
