In which quadrants do solutions for the inequality y is greater than one fifth times x plus 3 exist? i and ii i, ii, and iii i, iii, and iv all four quadrants

The solutions of the inequality exist in quadrants I,II and III

Step-by-step explanation:

we have

The solution of the inequality is the shaded area above the dashed line

The slope of the dashed line is positive (m=1/5)

The y-intercept of the dashed line is (0,3)

The x-intercept of the dashed line is (-15,0)

using a graphing tool

see the attached figure

The solutions of the inequality exist in quadrants I,II and III

THE CORRECT ANSWER IS  I,II, AND III

Step-by-step explanation: CALCUlista is correct

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.
