Given f(x) = 3/2x - 5 and g(x) = x^2 + 2x solve for g(-2)

g(-2) = 0

Step-by-step explanation:

Given

g(x) = x^2 + 2x

we have to find value of g(-2)

to get that we

need to x = -2 in g(x)

g(x) = x^2 + 2x

g(-2) = (-2)^2 + 2*(-2) = 4 -4 = 0

Thus,  g(-2) = 0

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.
