Answer:
The slope of the equation is -3.
Step-by-step explanation:
Given : Mr. Mole's burrow lies 5 meters below the ground. He started digging his way deeper into the ground, descending 3 meters each minute.
To find : What is the slope ?
Solution :
Let x be the number of minutes taken to dig the ground.
He started digging his way deeper into the ground, descending 3 meters each minute i.e. '-3x'
Let y is the total distance travel to dig the ground.
Mr. Mole's burrow lies 5 meters below the ground.
The equation form is 
Comparing with general slope form i.e.
where m is the slope.
The slope of the equation is -3.
1.1x+1.2x-5.4=-10
11/10x+12/10x-54/10=10
11x/2.5+2^2-1*3/5x-3^3/5=-10
(11x)+2(2*3x)+2(-3^3)/2*5=-10
11x+2(6x)+2(-27)/2*5=-10
11x+2*6x-2*27/2*5=-10
11x+12x-54/2*5=-10
23x-54/2*5=-10
23x-54=-100
23x=-46
23x/23=-46/23
x=-2*23/23
x=-2
Answer:
x=4
Step-by-step explanation:
3x-3=9
+3=+3
3x=12
3x=12
divide both sides by 3
leaving x by itself
12/3=4
x=4
