Answer:
y = -4x - 40
Perimeter = 5x^2 + 6x + 1
Area = 20x^3 + 23x^2 - 2x - 6
Step-by-step explanation:
That's how mafia works
Answer:
m = -4 is the slope
(x1, y1) = (12, 8) is a point on the line
The point-slope form is:
y - y1 = m(x - x1)
y - 8 = (-4)(x - 12)
The slope-intercept form is:
y = 8 + (-4)x + 16
y = (-4)x + 24
The standard form is:
y + (-4)x = 18 multiply both sides by 4
-4x = 18*4
-4x = 72
Step-by-step explanation:
2) Perimeter = 5x^2 + 2x -2
=7x^2 -2
L =49x -2
W=4x+3
49 -2 =47 x 16+3 = 19
A = 47x19
A = 893
P= 47+47+19+19= 132

Answer:
the two numbers are -5 and 1
Step-by-step explanation:
Let x and y be the first number and second number respectively.
According to the question, we can find 2 equations:
2x + 5y = -5
3x + 10y = -5
On solving,
x = -5
y = 1
