Answer:
$8190
Step-by-step explanation:
So we know that were putting away $2 each month from our allowance.
Jan-$2
Feb-$4
March-$8
April-$16
Ok so we already put away 4 months of our allowance from 12. So we need 8 more months to count how much.
So lets add: 2 + 4 + 8 + 16=30
Now we need to figure out how much in May and so on.
May- 16x2=32
June-32x2=64
July-64x2=128
August-128 x 2=256
September-256 x 2=512
October-512 x 2=1024
November-1024 x 2=2048
December-2048 x 2=4096
In total to add:
2 + 4 + 8 + 16 + 32 +64 + 128 + 256 + 512 + 1024 + 2048 + 4096 = 8190
Hope this helps :)

Answer:
∠ 2 = 104°
Step-by-step explanation:
- 8x - 48 = 9x + 275 [ alternate angles are equal ]
-8x - 9x = 275 + 48
-17x = 323
x = -19
9x + 275 = 9 × -19 + 275
= - 171 + 275
= 104°
∠ 2 = ( 9x + 275 ) [vertically opposite angles ]
∠ 2 = 104°
Answer:
y = 2x + 3
Step-by-step explanation:
As we go from (9,7) to (13,5), x increases by 4 and y decreases by 2. Thus, the slope of line p is m = rise/run = -2/4, or m = -1/2.
A line perpendicular to p will have a slope that is the negative reciprocal of the slope of p: -1 / {-1/2}, or m = 2.
One example of such a perpendicular line is y = 2x + 3. Here I borrowed the slope m and invented the y-intercept, b.
Is it rotated clockwise or counterclockwise?
- If clockwise, the coordinates of S are (4, -2).
- If counterclockwise, the coordinates of S are (-4, 2).
