Answer:
The graph of image and preimgae is shown below.
Step-by-step explanation:
From the given figure it is noticed that the vertices are A(-2,2), B(5,2), C(5,0), D(0,0), F(0,-2) and G(-2,-2).
It is given that figure ABCDFG is rotated by positive 90° about the origin (0,0).
Positive means counter clockwise and negative means clockwise.
If a figure is rotated by counter clockwise 90° about the origin (0,0), then
The vertices of image are
The graph of image and preimgae is shown below.
Answer:
C
Step-by-step explanation:
Both of the y= make upward parabolas
It is also going into the positive direction so it is
If there are x red marbles initially then 1/5 is a probability in it's lowest form cancelled down from:
<span>1/5 = x/5x </span>
<span>so there are 5x total marbles, x red and 4x blue. </span>
<span>Add 5 new red and the new probability is: </span>
<span>(x+5)/(5x+5) = 1/3 </span>
<span>3x+15 = 5x+5 </span>
<span>2x = 10 </span>
<span>originally there were: </span>
<span>x = 5 red </span>
<span>4x = 20 blue </span>
<span>marbles. </span>
<span>*************** </span>
<span>there are now: </span>
<span>x+5 = 10 red </span>
<span>4x = 20 blue </span>
<span>marbles.
hope it helps</span>
