its an example of quadratic
Answer:
-1/8
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Since BD and AE are parallel lines, then
∠BDC = ∠AED ( corresponding angles ), thus
4x - 5 = 97 - 2x ( add 2x to both sides )
6x - 5 = 97 ( add 5 to both sides )
6x = 102 ( divide both sides by 6 )
x = 17, hence
∠AED = 97 - 2x = 97 - (2 × 17) = 97 - 34 = 63°
∠BDE and ∠AED are same side interior angles and are supplementary, thus
10y - 3 + 63 = 180
10y + 60 = 180 ( subtract 60 from both sides )
10y = 120 ( divide both sides by 10 )
y = 12 → D
The double bar graph shows the number of imports and exports for a company in a certain week.
On how many days was the number of exports greater than the number of imports?
Answer: From the given double bar graph, we clearly see:
Number of imports for a company on Monday = 15
Number of exports for a company on Monday = 7
Number of imports for a company on Tuesday = 18
Number of exports for a company on Tuesday = 9
Number of imports for a company on Wednesday = 14
Number of exports for a company on Wednesday = 14
Number of imports for a company on Thursday = 15
Number of exports for a company on Thursday = 6
Number of imports for a company on Friday = 9
Number of exports for a company on Friday = 19
From the above information, we clearly see that only on Friday the number of exports are greater than number of imports. Therefore, there is only 1 day when the number of exports greater than the number of imports.
Hence the option D. 1 is correct
