Answer:
When you see a formula like this, try to operate, so you will see some identities sooner or later. In this case, we have a substraction identity:
\frac{cos ( \alpha - \beta )}{cos \alpha cos \beta } = \frac{cos \alpha cos \beta + sin \alpha sin \beta }{cos \alpha cos \beta } = 1 + tan α · tan β
Step-by-step explanation:
Answer:
y = -3/4x + 4
Step-by-step explanation:
y = mx + b
-2 = (-3/4)(8) + b
-2 = -6 + b
4 = b
y = -3/4x + 4

Answer: <em><u>
Less Than</u></em></h2>
Step-by-step explanation: 7^2 = 49, but 3^4 = 81. 49 < 81
Answer:
4x - 15
Step-by-step explanation:
Y=12x
Check: 72=12(6)
72=72
y=12x
y=12(10)
y=120
when x is 10 y is 120
