Answer: option first, f(0)=g(0) is true statement.
Explanation:
Since, According to the given graph, for the given function f(x), values of f(0)=-2 and f(-2)=4
While, for the given function g(x), values of g(0)=-2 and g(-2)=-4
So, we can say that f(0)=g(0)=-2
But, f(-2)≠g(-2), f(0)≠f(-2) and f(-2)≠g(0)
Thus, f(0)=g(0) is true.
Answer:
1. Fixed cost is $800
2.Cost of 25 bags is $1025
3. (170,2300)
Step-by-step explanation:
Given
Solving (a): Fixed cost
From the question, fixed cost is when x = 0;
Substitute 0 for x in
<em>Hence, the fixed cost is $800</em>
Solving (b): Cost of making 25 items
Here; x = 25
Substitute 25 for x in
<em>Hence, the cost of 25 bags is $1025</em>
<em></em>
Solving (c): Domain and Range where Maximum cost = $2300
Here; c(x) = 2500
Substitute 25 for c(x) in
Subtract 800 from both sides
Divide both sides by 10
The domain and range of a function is in form of (x,c(x))
<em>Hence, the domain and range is (170,2300)</em>
Answer:
<em>x </em>= -5
Step-by-step explanation:
You have to work backwards.
53 + 7 = 60
60 ÷ 12 = 5
Add the negative »»» -5
Answer:
I think the answer is 12
Step-by-step explanation:
Because Jo made $3 6 times so you multiply that by what Lelia makes. So 2 x 6 = 12?
So to find the zeros you need to break down the problem into two sets of parenthesis. So you need to figure out what two numbers multiply to get -5 and when added give you -4. Start by writing the factors of 5.
1,5 so now you have the two numbers, since the answer has to be negative we need to figure out which one needs to be negative so that when we add them we get -4
-1+5=4
1+-5= -4
Now that we have that we can see our factors are 1 and -5 so we write it like this
(X+1)(x-5)
To find our zeros we take each parenthesis and set them equal to zero
X+1=0
X-5=0
Now solve
X=-1
X=5
These two numbers are where the parabola will touch the x axis. Now you need to graph the point they give you. That’s I’ll be the center of the parabola. Next put a dot on (-1,0) and (5,0). Now to figure out which way to draw the parabola you just look at the sign in front of the x^2 on the original equation. Since there’s no negative sign your parabola will open upwards. Hope this helps
