The <em>correct answer</em> is:
f(x) = -10x², f(x) = 2x², and f(x) = 0.5x²
Explanation:
For a quadratic in standard form, f(x) = ax²+bx+c, the value of a describes the width and direction of the parabola. If a is positive, the parabola is open upward. If a is negative, the parabola is open downward.
If a < 1, a fraction or decimal, the graph is wider than the parent function f(x)=x². If a > 1, the graph is narrower than the parent function f(x)=x². The larger the value of a is (a > 1), the narrower the graph is. This makes the function with the decimal value of a the widest; the remaining graphs are in order of the value of a, least to greatest.
You can also approach it this way:
28 flowers times n = 3444
so n = 123
11 x 123 = roses, 17 x 123 = tulips.
Those 2 products should add up to 3444.
36 x 10 = 6 x 6 x 2 x 5 = 3 x 2 x 3 x 2 x 2 x 5
3 x 3 x 2 x 2 x 2 x 5
Answer:
Ty covered the least distance per min.
Step-by-step explanation:
Who covered the shortest distance per minute, or who rode his bike most slowly?
Andre's rate: (750 m) / (3 min) = 250/3 m/min
Rick's rate: (800 m) / (4 min) = 200 m/min
Ty's rate: (950 m) / (5 min) = 190 m/min
Ty was the rider who covered the least distance per minute; his rate was the slowest.
