I’m going to say A
Sorry if I’m wrong
40 ÷ 6 = 6.66 recurring 7 people are likely to have flu symptoms
The only 'small number' that I know that would affect the answer is an exponent that looks like ³ so the problem would be x³+x
remember that x³=x times x times x
if x=3 then
3³+3=27+3=30
Answer:
See attached picture. :)
Step-by-step explanation:
Simply look at the given x values in the table and whatever x equals in the table, put that value in the equation. For example, y = -x + 7. In the table x value, 0 is given, so the equation will now be y = 0 + 7. So y = 7 and so forth.
To graph, you take the given x value, 0, and the y value you solved for, 7. Your point on the graph would be (0 , 7). Continue repeating these steps till you complete the table and your graph. :)
The enclosed shape is that of a trapezoid. The area of a trapezoid is the product of the height of it (measured perpendicular to the parallel bases) and the average length of the two parallel bases. The formula is generally written ...
... A = (1/2)(b₁ + b₂)·h
Here, the base lengths are the y-coordinates at x=4 and x=9. The height is the distance between those two x-coordinates: 9 - 4 = 5.
You are expected to find the y-values at those two points, then use the formula for the area of the trapezoid.
You can save a little work if you realize that the average of the two base lengths is the y-coordinate corresponding to the average x-coordinate: (9+4)/2 = 6.5. That is you only need to find the y-coordinate for x=6.5 and do the area math as though you had a rectangle of that height and width 5.
Going that route, we have
... y = 2(6.5) - 1 = 13 - 1 = 12
Then the trapezoid's area is
... A = 12·5 = 60 . . . . square units.
