Answer:

3

Step-by-step explanation:

f(-1)g(-1) \text{ is the same thing as } f(-1)\cdot g(-1). \\\text{Therefore, find f(-1) and g(-1)}

f(-1)=(-1)^2-4\\f(-1)=1-4\\f(-1)=-3

g(-1)=3(-1)+2\\g(-1)=-3+2\\g(-1)=-1

Therefore:

f(-1)\cdot g(-1)\\=(-3)(-1)=3

Answer:
amount of nuts = 2 pounds
amount of dried fruit = 4 pounds

Explanation:
We are given that x is the amount of nuts and y is the amount of dried fruit.
We are also given that:
1- Hunter needs to make 6 pounds of trail mix. This means that:
x + y = 6
This can be rewritten as:
x = 6 - y .........> equation I
2- x costs $4 per pound, y costs $3.5 and Hunter can spend a total of $22. This means that:
4x + 3.5y = 22 ..........> equation II

Substitute with equation I in equation II and solve for y as follows:
4x + 3.5y = 22
4(6-y) + 3.5y = 22
24 - 4y + 3.5y = 22
24-22 = 4y-3.5y
2 = 0.5y
y = 4 pounds

Substitute with y in equation I to get the value of x as follows:
x = 6-y
x = 6-4
x = 2 pounds

Hope this helps :)

What is three fourths the square of b
lana [24]
Simplifying it would make it 3/4b^2. I can't write it down the correct way, but it's three over four times b squared. Unless it's a square root, then things would be different.
