Answer:
(1, 2)
Step-by-step explanation:
Given the equation of the lines x + 2y = 5 and 2x - 3y = -4
First we need to make x the subject of the formulas
For x+2y = 5
x = 5 - 2y ... 1
For 2x - 3y = -4
2x = -4+3y
x = (-4+3y)/2 ... 2
Equate 1 and 2
5 - 2y = (-4+3y)/2
2(5-2y) = -4+3y
10 - 4y = -4+3y
-4 -3y = -4-10
-7y = -14
y = 14/7
y = 2
Substitute y = 2 into 1
x = 5 = 2y
x = 5 - 2(2)
x = 5 - 4
x = 1
Hence the point where the lines meet will be at (1, 2)
Answer:
10 m
Perimeter = 24 m
Step-by-step explanation:
( Hypotenuse )² = 6² + 8²
= 36 + 64
= 100
= 10 x 10
( Hypotenuse )² = 10²
Hypotenuse = 10 m
Perimeter is the sum of all sides in a triangle.
Perimeter = 6 + 8 + 10 = 24 m
