Answer:
i.e. relation between speed-distance-time is one such situation that can be modeled using graph
Step-by-step explanation:
There are many real world examples that can be modeled using graph. Graphs are represented on co-ordinate planes, so any real world example that can be represented by use of linear equation can be represented onto a graph.
One such example, is speed-distance-time relation. Uniform speed can be represented on a graph as shown in figure.
So, the equation for speed is represented by equation as follows:
So, if we take distance on y axis and time on x axis with points as (distance,time)
(0,0) ==> 
(1,2) ==> 
(2,2) ==> 
the following points 0,0.5,1 will be plotted on graph. Similarly, more values can be plotted by assuming values for distance and time.
7*y - 5*(4-2y) = 7y - 20 +10y = 17y-20 = 31,
y =3, x = -2.
Weird 20 min without answer!
Answer:
(a). Function 1
(b) Function 2
(c) Function 1,2 and 4
Step-by-step explanation:
Find the equation for all functions;
function 1: y= 2x+1
function 2: y= -2x+3
function 3: y= 5x-2
function 4: y= -4x-4
for answer of (a) y= mx+c
c is intercept. so function 1 has closest intercept to 0
for (b) the greatest y intercept is function 2
for(c) slope is m: we have function 1, 2 and 4
First, let's find out how many 5/6 pound bags he can fill with one 2 pound bag.
2 ÷ 5/6
2 × 6/5
2.4
He can fill 2.4 bags with one 2 pound bag.
Now, we just need to multiply 2.4 by a number that will make it a whole number.
We'll use guess and check.
2.4 × 2 = 4.8
2.4 × 3 = 7.2
2.4 × 4 = 9.6
2.4 × 5 = 12
12 is a whole number.
This means that Chad needs to buy 5 of the 2 pound bags to fill 12 of the 5/6 pound bags, and he will have not peanuts leftover.
