<span>Evaluate ƒ(–3) for ƒ(x) = –5x2 + 2x –1.
</span>ƒ(x) = –5x2 + 2x –1
First, Substitute x by -3 in the formula of the function and calculate as follows.
ƒ(-3) = –5x2 + 2x –1
Apply the Order of Operations.
ƒ(-3) = –5(-3)^2 + 2(-3) –1
Simplify
ƒ(-3) = –5(9) + 2(-3) –1
ƒ(-3) = –45 -6 –1
ƒ(-3) = -52
Therefore, The function of ƒ(–3) for ƒ(x) = –5x2 + 2x –1 is -52
Answer:
c is the answer because it's the answer
Step-by-step explanation:
I don't know how to explain
To determine the distance between the forest ranger and the fire, simply use the trig. ratio
Let the distance between the forest ranger and the fire
we have: angle theta = 18 degree
adjacent=350 and opposite = x
The best trig. ratio to use is:
Answer:
The axis of symmetry will be at 1
Step-by-step explanation:
The middle of -3 and 5 will be the axis :)
-3, -2, -1, 0, 1, 2, 3, 4, 5
-2, -1, 0, 1, 2, 3, 4
-1, 0, 1, 2, 3
0, 1, 2

Answer:
Part A:
I have attached the graph of this system of inequalities.
Part B:
Plug in (8,10) into both equations
10 > 3(8) + 10
10 > 24 + 10
10 > 34
This is false!
10 < (-3/4)(8) - 1
10 < (-3)(2) - 1
10 < -6 - 1
10 < -7
This is also false!
So, (8,10) is not included in the solution area for the system.
