Test statement #1.
f(x) = -0.3(x - 5)² + 5
This is the equation of a parabola with vertex at (5,5).
Therefore the function is symmetric about x=5.
The statement "The axis of symmetry is x=5" is TRUE.
Test statement #2.
f(x) is defined for all real values of x.
The statement "The domain is {x | x is a real nuber} is TRUE.
Test statement #3.
As x -> -∞, f(x) -> -∞.
f(5) = -0.3*(5-5)^2 + 5 = 5
Therefore f(x) is creasing over (-∞, 5) is TRUE.
Test statement #4.
As x -> +∞, f(x) -> -∞.
Therefore the curve is concave downward., and it has no minimum.
The statement "The minimum is (5,5)" is False.
Test statement #5.
The maximum value of f(x) occurs at the vertex because the curve is concave downward.
The statement "The range is {y | y≥5}" is False.
Answer:
The first three statements are True. The last two statements are False.
13+14=180°
12x-22+9x-29=180
21x-51=180
x=11
m<2=m<14
m<2=70°
5/2 which is 2 1/5 if you convert all of the answers
Can you please retype the equation for line r? I don’t understand
