No cause if I helmet cost $42 , 7 helmets will be $294.
$42 = 1 helmet
$? = 7 helmets
cross multiply = 42 × 7 = $294
Answer:
Step-by-step explanation:
Given

Determine the quotient
See attachment for complete process.
First, divide 125x^3 by 5x
Write 
at the top
Multiply 
by
Subtract from 125x^3 - 8
i.e.
Step 2:
Divide 50x^2 by 5x
Write 
at the top
Multiply by
Subtract from 50x^2 - 8
i.e.
Step 3:
Divide 20x by 5x
Write 
at the top
Multiply by
Subtract from 20x - 8
i.e.
Hence:
The general equation of a line is expressed as y = mx + b where m is the slope of the line and b is the y-intercept. The y-intercept is the value of y when the graph crosses the y- axis. Consequently, it is the value of y when x is zero. The slope is the rate of change of y with respect to the change in x. It is calculated from the ratio of the difference of two y values and the difference of the corresponding x values. Given the points would result to a line, we can determine those elements for the line as follows:
b = 36
m = (y2 - y1) / (x2 - x1)
m = (27 - 36) / (3 -0) = -3
So, the equation of the line would be y = -3x + 36.
