Average national teachers salaries can be modeled using the equation y=9.25(1.06)^n , where y is the salary in thousands of doll
kiruha [24]
y=9.25(1.06)^{n}
Plug in n to find y.
n would be 50 because 2020-1970=50.

Use order of operations to solve.
y=9.25(1.06)^{50} \\ y=9.25(18.42) \\ y=170.39

Since y is the salary in thousands, multiply 170.39 by 1000.
170.39*1000=17039

A teacher can expect to have about $17,039 as a salary in the year 2020.

Which is the equation of a line that passes through the points (1,4) and (-1,1)
horsena [70]

Answer:

The equation of the line is y = 3/2x + 5/2

Step-by-step explanation:

To find the equation of this line, start by using the two points with the slope formula to find the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (4 - 1)/(1 - -1)

m = 3/(1 + 1)

m = 3/2

Now that we have the slope, we can use that and either point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - 4 = 3/2(x - 1)

y - 4 = 3/2x - 3/2

y = 3/2x + 5/2
