Answer:
B is the answer that is incorrect and must be rejected.
Step-by-step explanation:
A trapezoidal shape need not have a line of symmetry to be a trapezoid.
Answer:
20
Step-by-step explanation:
use slope formula, y² - y¹ / x² - x¹
you'd get 2,400 / 120
divide that and you end up with 20.

Answer:
- exponent: -3
- coefficient: 4
Step-by-step explanation:
The coefficient of a term is its constant multiplier. The exponent is the power to which the base is raised.
The term 4·b^(-3) has an exponent of -3, a base of b and a coefficient of 4.
The exponent is -3; the coefficient is 4.
Since Cindy has 26 nickels at the start, this would translate as the y-intercept. Or the value of y when x is zero. In this case, when she has no rolls of nickels, she would still have 26. Since each roll has 40 nickels each, the function that models the number of nickels Cindy will have is
f(r) = 40r + 26
If she can only afford 10 rolls, then the maximum number of nickels Cindy will have is:
f(10) = 40(10) + 26 = 426 nickels
