Answer:
f=11
Step-by-step explanation:
If t=7, we can substitute it into the original equation:
f=(2)(7)-3
Simplify:
f=14-3
f=11

Answer:
x = 75°
y = 105°
Step-by-step explanation:
Angle subtended on the circumference of the circle is half of the angle subtended on the center of the circle.
Quadrilateral PQRS is a cyclic quadrilateral.

B
The end behavior of a positive cubic function states that as x approaches infinity, y approaches infinity.
Similarly, as x approaches negative infinity, y approaches negative infinity.
This means that when written in interval notation, the range is (-inf, +inf).
Answer:
-21
Step-by-step explanation:
6(6) + 3(-7(2) -5 )
36 + 3( -14 -5)
36 + 3( -19)
= -21
Answer: $20
Step-by-step explanation:
$500 - $210 = $290
$290 - ($65*2) = $160
$160 - $140 = $20
