Answer:
240
Step-by-step explanation:
1 percent=10 dollars
10 percent=100 dollars
=120 dollars in one year
times 2 [2x]=
240
Check:
10 times 10=100 dollars
100+20=120
x2=
120+120 <em>or</em> 120 times 2=
240
Answer:
refer to images
Step-by-step explanation:
plot the first point at y=-2
then use the slope to graph the line
left 1 up one - point left one up one -point
right 1 down 1 - point right 1 down 1 - point
Answer:
The correct option is 3. The image of X is X'(6,2).
Step-by-step explanation:
means the dialation by scale factor 2 and the center of dilation is Z.
If a figure dilated by scale factor k and the center of dilation is (a,b), then

From the given figure it is clear that the coordinates of X are (4,0) and the coordinates of Z are (2,-2), so the coordinates of image are


The image of X is X'(6,2). Therefore the correct option is 3.
820
Explanation: it is .82x (1,000/15,000)
Because you're trying to make them congruent, equal the two expressions to each other.
So, for #10 you would equal them so it would look like this.
2x+2=5x-19
Then you would just go ahead and simplify
2x+2=5x-19
-2x -2x

2= 3x -19
+19 +19

21=3x

3 3
x=7
This means that x should be 7. You can check this just by plugging it in
2x+2
2(7)+2 = 16
5x-19
5(7)-19= 16
Same with #11.
x+8=3x-14

x=11
Check.
x+8
11+8= 19
3x-14
3(11) - 14 = 19
