Answer:
(-1.5, 9) becomes (-1.5 ,-9)
Step-by-step explanation:
When we reflect across the x axis, the x coordinate stays the same, the y coordinate becomes the opposite (x,y ) becomes (x,-y)
(-1.5, 9) becomes (-1.5 ,-9)
The distance between the ship and the light house is 139.28 km.
Solution:
The given image shows, it is right triangle.
Height = 50 km
Base = 130 km
Hypotenuse = ?
Using Pythagoras theorem,
<em>In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.</em>
Taking square root on both sides, we get
Hypotenuse = 
Hypotenuse = 139.28 km
The distance between the ship and the light house is 139.28 km.
<u><em>Commutative:</em></u>
93 + (68 + 7) ⇒ (68 + 7) + 93
<u><em>Associative:</em></u>
93 + (68 + 7) ⇒ (93 + 68) + 7
<u><em>Identity:</em></u>
93 + (68 + 7) + 0 ⇒ 93 + (68 + 7)
Answer:
The answer to your question is L = 10 in , M = 9 in ; S = 5 in
Step-by-step explanation:
Data
longest side = 5 + x in
medium side = 4 + x in
shortest side = x
Perimeter = 24 in
Process
1.- Write and equation to solve this problem
Perimeter = longest side + medium side + shortest side
Substitution
24 = (5 + x) + (4 + x) + x
Simplification
24 = 5 + x + 4 + x + x
24 = 9 + 3x
24 - 9 = 3x
15 = 3x
x = 15/3
x = 5
2.- Calculate the lengths of the side
Longest side = 5 + 5 = 10 in
Medium side = 5 + 4 = 9 in
Shortest side = 5 in
