Because Sam is 19, and is 6 years older than Mia 19-6=13 so Mia is 13. Mia is also 3 years younger than Alice so Alice’s age= 13+3=16 so Alice is 16
Answer:
y= -3/4x+3
Step-by-step explanation:
3x+4y=12 first step is to isolate the variable
-3x -3x subtract 3x on both sides
4y=-3x+12
/4 /4 divide both sides by 4
y= -3/4x+3
Well the equation would be 4x +22= y. I don’t see a graph but if you give me a sec I will get back to you
To find out if a triangle is a right triangle, you can use the Pythagorean theorem(which can only be used for right triangles):
a² + b² = c² (c is the hypotenuse or the longest side) And you can plug in the side lengths into this equation. If they are the same number on both sides, it is a right triangle, if they are different numbers it is not a right triangle.
6.) a² + b² = c²
(4√3)² + (11)² = (13)²
(16(3)) + 121 = 169
48 + 121 = 169
169 = 169 It IS a right triangle
7.) a² + b² = c²
(5)² + (2√14)² = (9)²
25 + (4(14)) = 81
25 + 56 = 81
81 = 81 It IS a right triangle
8.) a² + b² = c²
(6)² + (√49)² = (√82)²
36 + 49 = 82
85 = 82 It is NOT a right triangle
9.) a² + b² = c²
(13)² + (2√39)² = (16)²
169 + (4(39)) = 256
169 + 156 = 256
325 = 256 It is NOT a right triangle
