Based on the graph, the sales manager published a report in May 2020 claiming that so far in 2020, the group had met its goal of doubling sales.
Is this conclusion correct? Why or why not?
OA
Yes, the conclusion is correct because each of the 2020 sales bars is at least twice as high as the 2019 sales bars, showing that
the sales are at least doubled.
OB.
OC.
Yes, the conclusion is correct because the advertising campaign was designed to double sales.
No, the conclusion is not correct because the graph shows only the first four months of the year.
No, the conclusion is not correct because the y-axis does not begin at zero, so the relative size of the bars does not represent
the ratio of 2020 sales to 2019 sales.
OD.
No, the conclusion is not correct because the y-axis does not begin at zero, so the relative size of the bars does not represent the ratio of 2020 sales to 2019 sales.
What is a graph?
A graph can be described as a pictorial representation of data. A graph is made up of a y-axis and the x-axis. The y-axis must begin at zero.
Examining the given graph, the y-axis does not begin at zero. Also, the length of the bars in 2020 is not twice then length of the bars in 2019.

Answer:
#8 - 52°, #9 - 29°
Step-by-step explanation:
8. The two angles added together are a straight line, so they sum up to 180 degrees.
x + (2x + 24°) = 3x + 24° = 180°
3x + 24° = 180°
3x = 156°
x = 52°
9. Similar to #8. "Supplementary" means they add up to 180° (whether they are actually next to each other or not).
So, 4x + (2x + 6°) = 180°
6x + 6° = 180°
6x = 174°
x = 29°
Hope this helps. Get some rest. Zzzzz :)

Which of the following functions has two zeros at (−4, 0), (1, 0), and a y-intercept at (0,−2)?
Solve for x in the figure below
Answer:
x = 20
Step-by-step explanation:
5x - 21 = 2x + 39 (corresponding angles are congruent)
Collect like terms
5x - 2x = 21 + 39
3x = 60
Divide both sides by 3
3x/3 = 60/3
x = 20
