1. x+y=-3 (or, x = -y-3)

2. x*y=-54

Use equation 1 to substitute for x in equation 2:

(-y-3)*y = -54

y2+3y = 54

y2 + 3y - 54 = 0

Factor&solve:

(y+9)(y-6)=0

y = {-9,6}

(x,y)={(6,-9),(-9,6)}

6 & -9

union means to group the given sets. where as intersection means to pick out the common elements from the given sets.

if set a has 1,2,3 elements and B has 1,2,3,4,5. then its union will have 1,2,3,4,5 as its elements. and its intersection will have 1,2,3 as its elements.

A map scale of 1 to 5000 would show about a mile of city in a foot of map space. That is good enough to show the typical 10 - 16 streets per mile found in many cities.

A scale of 1 to 500000 would show 100 miles in a foot wide map. You could show Baltimore and Washington on the same page. This would not allow showing any small or medium sized streets.

To answer this question we need to first convert 1 km in miles and then 4 minutes into hours.

First 1 mile = 1.6 km

So 1 km / 1.6 = 0.625 miles (approximately)

Now 60 minutes = 1 hour

So 4/60 = 1/15 of an hour

Since speed = distance/time we have

Speed = 0.625/1/15 = 9.375 miles per hour.

There are 100 yards between end zones on a football field. Each yard is equal to 3 feet so there are 300 feet between end zones. 1500 feet divided by 300 feet is 5, so 1500 feet is the length of 5 football fields.

In mathematics, the cardinality of a set is a measure of the "number of elements of the set". For example, the set A = {2, 4, 6} contains 3 elements, and therefore A has a cardinality of 3. There are two approaches to cardinality - one which compares sets directly using bijections and injections, and another which uses cardinal numbers.
