How do i solve the equation 9+t/12=-3?

t=-144

Step-by-step explanation:

t in (-oo:+oo)

t/12+9 = -3 // + 3

t/12+3+9 = 0

1/12*t+12 = 0 // - 12

1/12*t = -12 // : 1/12

t = -12/1/12

t = -144

t = -144

Step-by-step explanation:

Isolate by the t on one side of the equation.

First, subtract 9 from both sides.

Solve.

Then, multiply by 12 from both sides.

Solve.

Multiply.

The correct answer is t=-144.

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.
