If Malcolm has driven 418 miles which is rounded to 420, and he has driven 384 miles which is rounded to 380, he has driven around 800 miles so far. Then you would subtract 800 from 1,273 you would get around 470 miles. That means Malcolm has 470 miles left to drive.
The slope-point form: y - y₁ = m(x - x₁).
The slope-intercept form: y = mx + b.
We have:
and the point (-5, 7)
therefore
The correct answer is C.
14%p can be written as 0.14p, since 14%=14/100=0.14.
Adding this to p means paying 100% of p plus an additional 14%. This would be equivalent to paying sales tax on a purchase.
