C.
This is correct because it multiplies the numbers shown above correctly.
Answer: Reflection across = -2; clockwise rotation
Step-by-step explanation: To get this answer, you first must work out the other answers. If you reclect across the x-axis and rotate 90 degrees clockwise, you'll find the shape to be in almost the exact same place it was before.
The third choice is illogical, because if you reflect over the y-axis, the shape is nowhere near where you need it to be, and rotating it 90 degrees counterclockwise is gonna bring it back to where you started.
The fourth option is the same as the third yet this time the clockwise rotation will bring you down to the negative y's, which is the opposite of where you need to be.
Therefore, that is why the first option is the better one to choose. Reflecting the shape over x = -2 is going to give you the correct orientation you needed for the 90 degree rotation.
I hope this helps!
First let's reduce the feet to miles
there are 5280 feet in a mile therefore
26400 feet=5 miles
31680 feet=6 miles
Jet A(the first jet) descends 5 miles in 96 miles
Jet B(the second jet) descends 6 miles in 120 miles
We can compare these as fractions to see which is steeper. This can be viewed as slope and the origin (0,0) is the airport.
slope: 6/120=?=5/96
1/20=?=5/96
Now we know that 5/100 =1/20 so 5/96 must be bigger than 5/100 because you are dividing by a smaller number.
so 1/20<5/96
So Jet B is descending steeper than Jet A.
As for linear model, I don't exactly know what your teacher means but I think I actually used the linear model when I'm thinking of steepness as slope in the coordinate plane, I will include a picture.
In this extremely zoomed out graph, you can see the blue line is just slighly higher than the red line(slope as in explanation is way easier to tell) this could be seen as the linear model) :) Hope it helped!
