<span>110.40 x.065 = $7.17600 in sales tax
total cost is 110.40 +7.17600 = </span>117.57600
The desired answer is probably that
2x + 1 = 67
is the equation that can be used to solve the problem. In this case, x represents the smallest integer.
_____
I like to work problems in consecutive integers by considering their average. Here, it is 67/2 = 33.5. The two consecutive integers whose average is 33.5 are 33 and 34, the solution to the problem. For this, the first equation applies, where x is the value halfway between the two integers. (This answer (2x=67) would likely get marked wrong by your computer grading system.)
Answer:
neither
Step-by-step explanation:
if you put those coordinates on a graph it would be curved and not be linear
X cannot be negative, so the first option and the third option are out.
when x = 1, f(x) = -1; when x = 4, f(x) = -2 and when x = 9, f(x) = -3. Hence the last option.
