I got 6x+3
The three equations are:
(2x-6) + (3x+1) + (x+8) =perimeter
2x+3x+x/1x=6x
-6+1+8= 3
The slope of a line perpendicular to another line has a
slope which is the negative reciprocal of that line or:
m1 = -1/m2
First, we convert the given equation into slope-intercept
form of a line: y = mx + b
8x + 15y = 12
15y = -8x + 12
y = (-8/15) x + 0.8
m1 = -8 / 15
Therefore the slope of the perpendicular line is:
m2 = 15 / 8
Since the perpendicular line crosses the point (11, 17), therefore
using the slope formula:
m = (y2 – y1) / (x2 – x1)
15 / 8 = (y2 – 17) / (x2 – 11)
1.875 (x2 – 11) = y2 – 17
1.875 x2 – 20.625 = y2 – 17
y2 = 1.875 x2 – 3.625
y = (15/8) x – 3.625
multiplying both sides by 8:
8y = 15x – 29
rewriting in standard form:

Answer:
X must be a number more than 3
X could be 5
Step-by-step explanation:
If x was 5, -3+5 would equal 2. This is a positive number.
If we said that X was a negative number such as -4, it would not work because -3-4=-7. That means that X equals -7. This is not a valid answer as it is a negative number.
This was just a guess, please check.
Answer:
Step-by-step explanation:
diameter = length of the box = 2p - 4 = 2(p - 2)
radius r = 2(p-2)/2 = p - 2
Area of the box occupied by container = πr² = 22/7 * (p-2)²
Answer:
1. 146 2. 4
Step-by-step explanation:
9^2 * 2 - 4^2
81 * 2 - 16
162 - 16
146
2 * (10 - 2) / 2^2
2 * 8 / 4
16 / 4
4
Hope this Helps!!!
