-4x - 11 = 2(x - 3x) + 13
-4x - 11 = 2x - 6x + 13
-4x - 11 = -4x + 13
-4x + 4x = 13 + 11
0 = 24...incorrect......no solutions for this problem
Answer:
13.4 x 2 = <em>26.8</em>
<em>12.5</em>
HYPOTENUSE:
10^2 + 12.5^2 = 256.25
Square root of 256.25 = around 16
which would equal 256
<em>16 </em>is your hypotenuse.
26.8 + 12.5 + 16 = 55.3 is your perimeter
Y - 3x = -8
y = 3x - 8...slope here is 3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -1/3.
y = mx + b
slope(m) = -1/3
(3,2)...x = 3 and y = 2
now we sub and find b, the y int
2 = -1/3(3) + b
2 = -1 + b
2 + 1 = b
3 = b
so ur perpendicular equation is : y = -1/3x + 3
