Answer:
cos60° = 
Step-by-step explanation:
Using the cofunction identity
• cos(90 - x)° = sinx°, hence
sin30° = cos(90 - 30)° = cos60° = 
Answer:
Use the equation mx+b=y
mx represents the slope and b represents the y intercept.
So, this would mean the equation is : 1/2x + -7 = y
Answer:
-7.
Step-by-step explanation:
Fractions are division! If you don't know what a quotient is, It is basically a more complicated way of saying "find the answer by dividing." So we always divide the numerator (top number) by the denominator (bottom number). So we get 14÷-2 and we can see that -2 is a negative number, so remember that a positive times or divided by a negative is always a negative number. So therefore we get -7 as our quotient.
