You will need 10 CAT6 cables for wiring computers in a new office. A local computer store sells them for $4.00 each plus 6% sale

s tax. You can order them from an Internet shopping site that offers them for $3.50 each plus $5.95 shipping and no sales tax. The Internet store offers free shipping when you order a box of 12 for $40.00. Which of the following is the best deal?

Store=10*4*1.06=$42.40

Internet=10*3.5+5.95=$40.95

And if you order an extra two to cancel out shipping...

Internet=$40.00

So the box of twelve is the best deal as it costs less than the other two options and gives you two spare cables. :P

If the x-intercept (–68, 0), and the y-intercept (0, –34), what is the equation?
stealth61 [152]

y = - \frac{1}{2} 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 = \frac{-34-0}{0+68} = \frac{-34}{68} = - \frac{1}{2}

the y-intercept = (0, - 34 ) ⇒ c = - 34

y= - \frac{1}{2} x - 34
