Alexander and his children went into a grocery store and he bought $6 worth of bananas and peaches. Each banana costs $0.60 and each peach costs $1.50. He bought a total of 7 bananas and peaches altogether. graphically solve a system of equation in order to determine the number of banana, x, and the number peaches ,y, Alexander bought. please graph.

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
