I don't understand what you're saying. If you mean rounding, it would be rounded to 80-60, which would equal 20.

Answer:

325 miles and 77 dollars

Step-by-step explanation:

First, create equations. Let x equal the miles driven. The first plan expression is 38 + 0.12x and the second plan expression is 51 + 0.08x. Setting these equal and solve for x: 38 + 0.12x = 51 + 0.08x -> 0.04x = 13 -> x = 325 miles.

The cost is found by substituting it into any of the expressions: 51 + 0.08(325) = 77 or 38 + 0.12(325) = 77

Answer:

$x = \frac{15}{4}$

Step-by-step explanation:

b) set up equations so they are equal to each other,

$2x - 2 = - 3x + 12$

$5x = 14$

$x = \frac{14}{5}$

this is when f(x)=g(x) so our approximation was close.

c)solving it graphically is nearly impossible because the solution can be any value around the intersection. only way to be sure is to solve it symbolically.
