Answer:
BC=4
Step-by-step explanation:
Use the distance formula
4
V(x) = (2x - 3)/(5x + 4)
The domain is all Real numbers except x = -4/5, because if x = -4/5 the denominator would be zero and you cannot divide by zero.
{x | x ∈ R, x ≠ -4/5}
w(x) = (5x + 4)/(2x - 3)
similarly, x ≠ 3/2
so, {x| x ∈ R, x ≠ 3/2}

Step-by-step explanation: how many points in each one??
Answer:
x=9
Step-by-step explanation:
side opposite to 90 degree is hypotenuse(longest side of a triangle) . And other two are the legs of the triangle.
using pythagoras theorem
a^2 + b^2 = c^2
12^2 + x^2 = 15^2
144 + x^2 = 225
x^2 = 225 - 144
x^2 = 81
x =
x = 9
Answer:
Yes
Step-by-step explanation:
The law of cosines relates the three sides of a triangle with the cosine of the angle opposite one of them. It is useful for finding an angle of the triangle when only the side lengths are given, as here.
