Let
A( 5.0,2.8) B( -2.8,5.1)
we know that
The formula to find the distance between two points is equal to
substitute in the formula
therefore
<u>the answer is</u>
the distance between these points is
4x=3(x-6)-2
distribute
4x = 3x-18 -2
combine like terms
4x =3x-20
subtract 3x from each side
x = -20
The boxes checked are right
a) true: In some instances, an irrational number can be added to an irrational number to become rational, but adding a rational number to one will not work
b) false: It only sometimes works
c) true: e.g. square roots --> (√5)² = 5
d) true: a rational number multiplied by any rational number will be rational
e) false: e.g. perfect squares --> √64 = 8
f) true: e.g. √(5/3) = (√5)/(√3) = (√5*√3)/3
