A linear equation has 1 for all exponents on the placeholders
aka the equation is first degree (aka the hightest exponent on placeholders=1) so
it is linear
y = -
x - 34
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 68, 0 ) and (x₂, y₂ ) = (0, - 34 )
m =
=
= - 
the y-intercept = (0, - 34 ) ⇒ c = - 34
y= -
x - 34
For example, if the question is to simplify square root x^7, you do 7/2=3......1
so the answer would be x^3 times square root x
Answer: 10 bags
Step-by-step explanation:
First we must calculate the field area. Assuming it is a rectangle then its area equals the product of its length times its width

You use 8 pounds of fertilizer per 1,000 square feet
So the amount of fertilizer you should use is:

As the fertilizer comes in bags of 50 pound then you need

Since you can not buy 9.2 bags then we round up to the next whole number.
Finally you need 10 bags of fertilizer
