For the 1 first problem you have to do additive inverse where the subtraction sign is and then combine all the z's and then combine the normal numbers and then put plus sign in between
Answer:
174 feet below sea level
Step-by-step explanation:
y is the number of minutes so you can multiply 14 by 9
14*9 is 126
then you add 126 to -300
126 + (-300) is essentially 126 - 300 and that is -174
the submarine was at 174 feet below sea level
-6 because for every value (x,y) there is another value (-x,y) so for the value (6,0) there must also be a value (-6,0). That is what the definition of y-axis symmetry is, it is also known as being an "even" function if it has this type of symmetry. Look at the graph of y=(x^2)-36 to see how this works.
