Flipping over the trigonometric functions of sine, cosine and tangent we have the following respectively
1/cscФ (sinФ), 1/secФ (cosФ) and 1/cotФ (tanФ). These are the identities for which they numerically equal when the numerator and denominator of these fractions are swapped.
The top square is 8. The long rectangle 19.5. The bottom rectangle is 3.
49=-7k is equivalent to D because when you simplify both of them, you get -7=k
Answer:
y = -2.5x + 4
Step-by-step explanation:
Slope intercept form: y = mx + b
Isolate the variable y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 5x from both sides.
5x (-5x) + 2y = 8 (-5x)
2y = 8 - 5x
Next, divide 2 from both sides to isolate the y.
(2y)/2 = (8 - 5x)/2
y = (-5/2)x + (8/2)
y = -2.5x + 4
y = -2.5x + 4 is your answer.
