What is an expression for the sale price of a bracelet that has been discounted 20% from its
sticker price? evaluate the expression for a sticker price of $40. use the variable for the sale
price and for the sticker price.
a. = - 0.2; $32
b. = + 20; $840
c. = + 0.2; $40
d. = - 0.8; $8

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11
