At a carnival, food tickets cost $2 each and ride tickets cost $3
each. A total of $1,240 was collected at the carnival. The number
of food tickets sold was 10 less than twice the number of ride
tickets sold.
The system of equations represents x, the number of food tickets
sold, and y, the number of ride tickets sold.
2x + 3y = 1240
x = 2y - 10
How many of each type of ticket were sold? - Answer 180 food
tickets and 350 ride tickets
Graph the function y = |8 - 2x| + 3. Which is a point on the
function? - Answer (6.2, 7.4)
Using only the values given in the table for the function, f(x) = x3
- 3x - 2, what is the interval of x-values over which the function is
decreasing? - Answer (-1,1)
The graph of f(x) = is reflected over the y-axis. Use the graphing
calculator to graph this reflection. Which list contains three points
, that lie on the graph of the reflection? - Answer (-81, 9), (-36, 6),
(-1, 1)
The formula for density is given by , where p is density, M is mass
and V is volume. If a substance has a mass of 27.82 grams and a
volume of 3.6 ml, what is the most accurate density of the
substance in g/ml? - Answer 7.73
The perimeter of a rectangular pool is more than 62 meters, and
the width is at least 10 meters less than the length. Which system
of inequalities represents the possible length in meters, l, and the
possible width in meters, w, of the pool? - Answer w ≤ l - 10
2l + 2w > 62
Hiroto solved the equation 6 - 4|2x - 8| = -10 for one solution. His
work is shown below.
6 - 4|2x - 8| = -10
-4|2x - 8| = -16
|2x - 8| = 4
2x - 8 = 4
2x = 12
x=6
