The rule for a rotation by 90 about the origin is <span>(x,y)→(−y,x<span>)
so
</span></span><span>(-6,-2) ---> (2, -6)
(-3,1) </span> ---> (-1,-3)<span>
(-1,1) </span> ---> (-1,-1)<span>
(2,-4)</span> ---> (4, 2)
Well, since the decimal is not terminating (not rational) it cannot be put into a fraction.
A. all inherited traits of an organism.
Genes are something you inherit from a family and are passed on. Sometimes you might skip your parents and inherit a trait from a another past relative.
Answer:
x = 18 , y = 45
Step-by-step explanation:
The angle vertically opposite 4x - 7 is congruent to it and forms a same- side interior angle with 6x + 7.
Same- side interior angles sum to 180° , then
6x + 7 + 4x - 7 = 180 , that is
10x = 180 ( divide both sides by 10 )
x = 18
Then
6x + 7 = 6(18) + 7 = 108 + 7 = 115
6x + 7 and 3y - 20 are vertically opposite angles and are congruent , so
3y - 20 = 115 ( add 20 to both sides )
3y = 135 ( divide both sides by 3 )
y = 45
Since there are 5 pens total, and three of those pens are blue, the probability for both pens being blue is 3/5.
(just like if the black pens were being chose the probability would be 2/5, since there are 5 pens total and 2 black pens.)<span />
