10 instead of 5 because 5 is only for a half hour
Not an equation for those 2 points, but rather "the equation of the line thru (4,6) and (-4,0).
6 - 0
Slope? m = ----------- = 6/8 = 3/4
4 -(-4)
Equation? Start with y = mx + b. Then 6 = (3/4)(4) + b, or 6 = 3 + b. b = 3.
The desired equation is y = (3/4)x + 3.
Answer:
b
Step-by-step explanation:
There are three groups of people: 25 years old and younger, between 25 to 50, and 50 years old and older. Their fractions must equal to 1 because these three together form the whole.
1 = 1/3 + 2/7 + x
where x is the fraction for people ages 25 to 50 years old
x = 8/21
So, the actual number of people ages 25 to 50 years old is:
84(8/21) = 32 people
I’m pretty sure it should be cos + cos
