Answer:
y = x/4 + 5
Step-by-step explanation:
Solve for y:
20 - 4 y = -x
Hint: | Isolate terms with y to the left-hand side.
Subtract 20 from both sides:
-4 y = -x - 20
Hint: | Solve for y.
Divide both sides by -4:
Answer: y = x/4 + 5
Step-by-step explanation:
Yes, one pair of opposite sides could measure 10 inches. and the other pair could measure 13 inches
Answer:

Step-by-step explanation:
The depth function is:

After 3 minutes, a submarine had descended to −320 feet.
This means that
. So


After 8 minutes, the submarine had descended to −420 feet.
This means that
. So


From the first equation:

So





And

So

Answer:
{0, 3, 12}
Step-by-step explanation:
Put the domain values in the function and evaluate. The result is the range values.
y = 3{-2, -1, 0}^2 = 3{4, 1, 0} = {12, 3, 0}
For the given domain, the range is {0, 3, 12}.
_____
<em>Additional comment</em>
Neither the domain nor range values need to be put in any particular order. However, it is often convenient for them to be arranged from least to greatest.
