The correct option is D ....
Step-by-step explanation:
Angle is ending at the point = (-3, -4)
Signs of both x and y are negative therefore it is in the third quadrant.
To find the the tangent of an angle we have to find the ratio of the length of the opposite side to the length of the adjacent side.
In this question the opposite side of the angle is of 4 units and the adjacent side of the angle is 3 units.
tanθ = y/x
tanθ = -4/-3
tanθ = 4/3
Thus the correct option is D ....
Answer:
f(x)+41 f(-10)=7
Step-by-step explanation:
Answer:
She didn't put the sign's in the proper place, it should be ( x + 3 ) ( x - 7 )
Step-by-step explanation:
( x - 3 ) ( x + 7 ) = x² + 7x - 3x - 21 = x² + 4x - 21
( x + 3 ) ( x - 7 ) = x² - 7x + 3x - 21 = x² - 4x - 21
