Set up a proportion.
Let x = the number of students in 29970 who speak 3 or more languages.
285/19 = 29970/x Cross multiply
285 x = 19 * 29970
285x = 569430
x = 569430/285
x = 5415 students speak 3 languages.
Anything multiplied by 0 will always equate to 0.
That means the two numbers are 8 and 0.
(0 × 8 = 0)

The picture attached has the table that repfesents the linear function to find the equation.
Answer:
Explanation:
A<em> linear function</em> is characterized by a constant slope and a unique y-intercept.
Let m be the slope and b the y-intercept of a linear function. Then, s<em>lope-intercept</em> equation has the form:
Using any two pair of points (x,y) from the table you can determine the values of m and b.
The table is:
x 0 1 2 3 4
y -6 4 14 24 34
You know that it is a linear function because for constant increases of the x-values (1 unit in the table) there is a constant increase of the y-values (10 in the table).
The slope, m, is calculated as:
- m = [change in y] / [change in x] = Δy / Δx = [14 - 4] [2 - 1] = 10
As said, you could have used any two points to calculate m,
The y-intercept, b, is the value of the function, y, when x = 0.
- From the table you can observe that when x = 0, the value of y is - 6; so b = - 6.
Thus, the equation of the linear function represented in the table in slope-intercept form is:
Ok because it only wants 3 significant digits your just take 103 and times it by the decimal form of 1.67% which is .0167 to get 1.720, now add that to 103 and multiply by .0167 again to get the populations after the second year(Use the population at that year to multiply by .0167). Do the same for the 3rd, 4th and 5th years and you should end with 112 million people.
