Michelle can run one lap of a cross-country in 1/5 hour. How many laps could she complete in 1 1/3

6

Step-by-step explanation:

She can run a whole lap in 12 minutes.

1 and 30 minutes divided by 12 is 6.

She can run 6 laps in 1 1/3.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
