Answer:
-5
Step-by-step explanation:
60 because y is substituting for 1 and if a number is 2y that means it is 2 because you multiple 2 and 1.
Answer:
y = 7 - 2x
Step-by-step explanation:
Note that:
y = height of the candle
x = hours
The candle starts at 7 inches, and can only grow smaller as it is burnt. It also burns in a constant 2 inches per hour. Note that it is "2 inches per hour, or 2 * h (h = hour). It is also burning, or taking away, from the original, or 7. Therefore, y = 7 - 2x is your answer.

Answer:
Part A: equations B and D are true
Part B: expression B is equal to tan(g)
Step-by-step explanation:
In the given triangle, sin(g) = cos(h) and cos(g) = sin(h).
___
Part A
Based on the above, selection B is true.
Based on the above, the equation of D becomes: sin(h)+sin(g) = sin(g) +sin(h), which is true.
Selections B and D are true
___
Part B
Based on the above tan(g) can also be written ...
tan(g) = cos(h)/sin(h) . . . . . corresponds to selection B
