According to the system:
5 – 7x + 2y² = -10
1 – 5x – 2y = -22
______________
a) No ; (4, 6) is not a solution to the
system. This point does not touch either equation.
b) No ; (6, 4) is not a solution to the system. This point does not touch either equation.
Solutions:
x = ( 122 ∓ 3√101 ) / 25 ≈ 3.674 or 6.086
y = ( -7 ± 3√101 ) / 10 ≈ 2.315 or -3.715
The perimeter of any shape is a measure of the length of the peripheral of that shape.
For a triangle, it is an addition of the length of the 3 sides.
P = a + b + c where a, b, c are the lengths of the individual sides.
p = 10x + 5y = (3x + 4y) + (5x - y) + c
Collecting like terms on the RHS, we have
p = 10x + 5y = 8x + 3y + c
Subtracting 8x + 3y from both sides to give c leaves us with
10x + 5y - (8x + 3y) = c
c = 10x - 8x + 5y - 3y
c = 2x + 2y

Answer:
20
Step-by-step explanation:
(6a + 10) = 130
(6 x 20) + 10 = 130
120 - 10 = 130
130 = 130
