X is 6.11431
so 6.1 rounded to nearest tenth
Answer:
Part 1) 
Part 2) 
Part 3) 
Step-by-step explanation:
we know that
The equation of the line into slope intercept form is equal to

where
m is the slope
b is the y-intercept
Part 1) we have
(10,-3) (5,-2)
<u><em>Find the slope</em></u>
The formula to calculate the slope between two points is equal to
substitute
<em>Find the value of b</em>
we have

substitute in the equation
and solve for b



substitute

Part 2) we have
(6,2) (7,5)
<u><em>Find the slope</em></u>
The formula to calculate the slope between two points is equal to
substitute
<em>Find the value of b</em>
we have

substitute in the equation
and solve for b



substitute

Part 3) we have
(4,4) (-7,4)
<u><em>Find the slope</em></u>
The formula to calculate the slope between two points is equal to
substitute
This is a horizontal line (parallel to the x-axis)
The y-intercept b is equal to the y-coordinate
<em>therefore</em>
The equation of the line is

Answer:

Step-by-step explanation:
Using the Quotient rule:

We can subtract the exponents of x and y:

Step-by-step explanation:
7 students were in the van so 187 - 7 = 180. 180 ÷ 4 = 45, there were 45 students on each bus. Not sure if this makes total sense, hope it helps
X decreased by the square of nine
x - 9^2 = x - 81
