using pythagorean theorem
a^2 + b^2 = c^2
(12x)^2 + (16x)^2 = 10^2
square each term
144x^2 + 256x^2 = 100
combine like terms
400 x^2 = 100
divide by 400 on each side
x^2 = 1/4
take the square root on each side
x = 1/2
Answer: x=1/2

The regular polygons could be used to make regular and semi-regular tessellations are equilateral triangle, square and regular hexagon. Therefore, the correct answers are A, B and D.
A regular tessellation is tessellation made up by using only one type of regular polygon. These are made up of completely congruent regular polygons all that connecting vertex to vertex.
Regular polygons have congruent straight sides. When we slide or rotate a regular polygon, the side of the original figure and the side of its translation will match.
Equilateral triangles, squares and regular hexagons are the only regular polygons that tessellate. Therefore, there are only three regular tessellations.
Therefore, the correct answers are A, B and D.

Answer:
y = x + 1
Step-by-step explanation:
y = mx + b
First, find the y-intercept. This is where the line intersects with the y-axis.
So, 1. -> y = mx + 1
Next, find the slope. For every 1/2 moving to the right, it also vertically increased by 1/2.
(1/2)/(1/2)
= 1 -> y = x + 1
Therefore, y = x + 1

i.e
Thus
Profit = (Cost of the 20 stock after 10 month - Cost of the 20 stock before 10 month ) × Total number of shares .
L.C.M of (4,2) = 4
Profit = 3 × 5
Profit = $15
Therefore the $15 profit would Caroline make .

7 . X + 2y = 4 (move x beside 4, since it's positive it will be negative)
2y = 4 - X (divide terms to 2)
| 2y ÷ 2 = y | 4 ÷ 2 = 2 | -X ÷ 2 = -1/2 (There's always an imaginary 1 beside x, only just x).
y = 2 - 1/2x (rearrange terms)
y = -1/2x + 2
9. -2x + 3y = -6 (move -2x beside -6, since it's negative it will turn into a positive)
3y = -6 + 2x (divide by 3)
y = -2 + 2/3x (rearrange)
y = 2/3x -2
11. 5x - 2y = 14
-2y = 14 - 5x (-2 ÷ -5x is 5/2x, but since numerator and denominator are negative, fraction turns positive)
y = -7 + 5/2x
y= 5/2x - 7
13. 4x + 3y = 12
3y = 12- 4x
y = 4 -4/3x
y = -4/3x + 4
15. x + 3y = -3
3y = -3 -x
y = -1 -1/3x
y -1/3x - 1
There you go!
Just remember those steps and you should be fine :)

Now, to find out how much rope is remaining, we subtract the length used from the total length of 10 meters: 10 - 6 = 4 meters.
Rachel then cuts the remaining rope into pieces of length 0.6 meters each. To find out how many such pieces she can make, we divide the remaining length by the length of each piece: 4 / 0.6 = 6.67.
However, since we cannot have a fraction of a piece, we round down to the nearest whole number. Therefore, Rachel cut 6 pieces of rope, each measuring 0.6 meters, from the remaining 4 meters of rope.
