Part a: explain why the x-coordinates of the points where the graphs of the equations y = 2^−x and y = 8^x+4 intersect are the solutions of the equation 2^−x = 8^x+4. part b: make tables to find the solution to 2^−x = 8^x+4. take the integer values of x between −3 and 3. part c: how can you solve the equation 2^−x = 8^x+4 graphically?

Part A: They intersect at 2^−x = 8^x+4 since the two graphs are equal therefore they give out the points where they meet / intersect.

Part B:

when x = -3

8 = 1/512 + 4 False

when x = -2

4 = 1/64 + 4 Closest

x ≈ -2

Part C:

Plot 2^-x

Plot 8^x + 4

Find the intersection points on the graph

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

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.
