2. f(x) = 3ǀ2x - 1ǀ + x, what is the output for the input -4?
im stumped pls help

output = 23

Step-by-step explanation:

x = -4

f(x) = 3ǀ2x - 1ǀ + x

f(x) = 3ǀ2(-4) - 1ǀ + (-4)

f(x) = 3ǀ2(-4) - 1ǀ - 4

f(x) = 3ǀ-8 - 1ǀ - 4

f(x) = 3ǀ-9ǀ - 4

f(x) = 3(9) - 4

f(x) = 3(9) - 4

f(x) = 27 - 4

f(x) = 23

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
