The graph shows the volume of oil (L litres) in a tank at time t seconds. a)find the gradient of the graph b)explain what this g

Alisiya [41]

Answer/Step-by-step explanation:

a. Using two points on the line (0, 2) and (4, 12), find the gradient:

Gradient = ∆y/∆x = (12 - 2) / (4 - 0) = 10/4 = 2.5

Gradient = 2.5

b. The gradient, 2.5, represents the unit rate. That is, the volume of the oil in the tank per second.

i.e. 2.5 litres per second

c. The value, L = 2 represents the y-intercept, which is the starting value or initial volume of oil in the tank at 0 secs.

Can somebody number the problem and work it out for me thanks and btw it’s solving system by graphics

adoni [48]

Answer:

Solutions are (3,1) and (4,2)

Step-by-step explanation:

Graph is shown in the attached sheet

Given are two systems of equations and we have to solve them using graph

For graphing let us first prepare table for x and y.

1) $y=\frac{-2x}{3} +3:\\y=2x-5$

I line II line

x 0 4.5 3 x 0 2.5 3

y 3 0 1 y -5 0 1

The two lines intersect at (3,1)

Hence solution is (3,1)

--------------------------------------------

2) $y=\frac{x}{2} \\-6x+3y=-18$

I line II line

x 0 2 4 x 0 6 4

y 0 1 2 y 3 0 2

The two lines intersect at (4,2)

Hence solution is (4,2)
