In this case, the total number of questions in the test is 50. The possible outcome for the question would be answered wrong, answered correctly or not answered. To know the amount of the correct answer, you need to multiply the incorrect with correct/incorrect ratio. The equation would be:
correct answer: 9 answer * 7/3= 21 answer.
Then for this test misty has:
9 incorrect answer
21 correct answer
20 blank/ not answered
You have to use the distance formula
which is:√(x2-x1)+ (y2-y1) (btw the whole equation is under the square root)
√(10- (-4) + (-2)- (-4)
√14+2
√16

There are 60 ( ' ) minutes in 1 degree, and 60 ( " ) seconds in 1 minute.
now, on a Latitude of 42.54°, there are 42° clearly, how much is the 0.54 anyway?
well, we know there are 60 minutes in 1 degree, therefore 0.54 * 60 is how many minutes in 0.54, or 32.4'. So a whole 32' and 0.4 of a minute.
how many seconds in 0.4 minutes? well, there are 60 seconds in 1 minute, thus 0.4* 60, or 24.
L42.54 is then 42° 32' 24".

Answer:
y=-2x-4
Step-by-step explanation:
y-y1=m(x-x1)
y-0=-2(x-(-2))
y-0=-2(x+2)
y=-2x-4+0
y=-2x-4
