The scale of the drawing is 1 cm to 10 feet. This means, every 1 cm of the drawing represents 10 feet in actual.
The trees are 5.2 cm apart in the drawing. So according to the given scale, they will be 5.2 x 10 = 52 feet apart in actual.
So actual bushes be planted at a distance of 52 feet.
        
             
        
        
        
Answer:
A. First equation by -2
Step-by-step explanation:
if you multiply the first equation by -2, the -4y cancels 4y
  
        
             
        
        
        
Answer:
6 and 8
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
Given this,
(3x)² + (4x)² = 10²
9x² + 16x² = 100
25x² = 100
Divide both sides by 25
x² = 4
x = 2
Substitute this into 3x and 4x.
3x = 3 * 2 = 6
4x = 4 * 2 = 8
Thus, the answer is 6 and 8
 
        
             
        
        
        
Answer:
y = (-1/2)x + 21/2
Step-by-step explanation:
Given equation:
y - 2x + 7 
Coordinates = (5,8)
Find:
Perpendicular equation
Computation:
y = mx + c
y - 2x + 7 
y = 2x - 7
So,
m = 2
The negative reciprocal of 2 is -1/2
So,
For,
Coordinates = (5,8)
y = mx + c
8 = (-1/2)(5) + c
8 = -5/2 + c
c = 8 + 5/2
c = 21 /2
So,
y = mx + c
y = (-1/2)x + 21/2
