Answer:
=3/7 × -2/5
=-6 / 35
Step-by-step explanation:
Answer: f(x)-g(x)=2x+5
Step by step:
f(x) = 3x+2
g(x) = x-3
f(x)-g(x) = 3x +2 - (x-3) = 3x + 2-x+3=2x+5
To solve for the last side of the triangle, use the Pythagorean Theorem:
(8)^2 + x^2 = (9)^2
x = sqrt of 17
However, this is a NEGATIVE sqrt 17 because the terminal side is in quadrant 4, meaning that this side is under the X-axis and therefore negative.
Now that you know the side opposite of u in the triangle, do opposite/hypotenuse.
sin u = -(sqrt 17)/9
Answer:
