The speed limit in the school parking lot is 15 miles per hour. nannette drove into school at a speed of 19 miles per hour. by how many miles per hour did nannette exceed the speed limit?

4 miles per hour.

Step-by-step explanation:

In order to calculate this you just need to withdraw from the speed at which Nannette was driving in the school parking lot the speed limit:

Excess of speed: Nannettes speed-speed limit

Excess of speed: 19 mph-15mph

Excess of speed:4 mph

So now we know that she was driving 4 miles over the speed limit.

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

x = 12

y = 1

for the points!
