For this case we have the following definition:
A real number can be a rational number or an irrational number.
The rational numbers are those that can be expressed as the quotient of two integers, such as 3/4, -21/3, 5, 0, 1/2, while the irrational numbers are all the others.
Between 0.1 and 0.11 we have:
Rational number: 105/1000 = 0.105
Irrational number: 01057685429832687
Its C because both 5x and 2x have the same x at the end and their both considered like terms. so the answer would be C and if it was to be solved 5x+2x= 7x and 7+7x would be the final answer. since the 7 with no x has no x, it wouldnt have to be solved or simplified
Advertising is x and revenue is y
(0,2)(2,6)
slope = (6 - 2) / (2 - 0) = 4/2 = 2
y = mx + b
slope(m) = 2
(0,2)...x = 0 and y = 2
now we sub and find b, the y int
2 = 2(0) + b
2 = b
so ur equation is : y = 2x + 2
spends 10 mill on advertising.....so x = 10
y = 2x + 2
y = 2(10) + 2
y = 20 + 2
y = 22.....so the revenue (y) of the company is 22 (million)
Median:
The median in this set is the 5th term.
Therefore the median in this set is 23.
The answers are in slope-intercept form, so you can see that the slope (coefficient of x) is only correct for choices b and c.
When you substitute x=3/2 into those equations, you find that b gives y=6 (correct) and c gives y=0 (incorrect).
The appropriate choice is ...
... b.) y = 2x+3
