1) They are carnivores and hunt for food.
2) They are herbivores and eat plants.
3) Some (like the ant) make food by farming.
Answer:
When ordering three or more fractions from least to greatest, compare two fractions at a time. It is helpful to write a number in a circle next to each fraction to compare them more easily.
Answer:
see below
Step-by-step explanation:
a) 2(x - 1) = 4 (x + 2)
Distribute
2x-2 = 4x+8
Subtract 2x from each side
2x-2x-2 = 4x-2x +8
-2 = 2x+8
Subtract 8 from each side
-2-8 = 2x+8-8
-10=2x
Divide each side by 2
-10/2 = 2x/2
-5 =x
b)(3 - x) (x + 2) = 0
We can use the zero product property
3-x = 0 x+2= 0
3-x+x=0+x x+2-2=0-2
3=x x=-2
Answer:
Minimum cost is $12427.85
Step-by-step explanation:
The unit cost C is given as:
where x is the number of cars made.
To determine the minimum cost, C(x), first we determine the minimum value of the quadratic expression
When a>0, C(x) will attain minimum value at the point determined by .
Comparing with the general form of a quadratic expression
a=0.3, b=-66, c=14571
Minimum Value occurs at
Therefore, the Minimum Cost, C(x) occurs at the point x=39.6
Substituting x=39.6 into C(x)
C(39.6)=
The Minimum cost is $12427.85
Answer:
Choose some points for x to find its y, the f(x).
To find its inverse, switch the x and y coordinates.
y = 3x + 1
y = 3(-3) + 1
y = -8
f(x) (-3, -8)
f⁻¹(x) (-8, -3)
y = 3x + 1
y = 3(-2) + 1
y = -5
f(x) (-2, -5)
f⁻¹(x) (-5, -2)
y = 3x + 1
y = 3(-1) + 1
y = -2
f(x) (-1, -2)
f⁻¹(x) (-2, -1)
y = 3x + 1
y = 3(0) + 1
y = 1
f(x) (0, 1)
f⁻¹(x) (1, 0)
y = 3x + 1
y = 3(1) + 1
y = 4
f(x) (1, 4)
f⁻¹(x) (4, 1)
y = 3x + 1
y = 3(2) + 1
y = 7
f(x) (2, 7)
f⁻¹(x) (7, 2)
y = 3x + 1
y = 3(3) + 1
y = 10
f(x) (3, 10)
f⁻¹(x) (10, 3)
