The basic form of linear function is
y=ax+b
For finding the slope, use the slope formula.
(4-2)/(-2+1)= 2/-1=-2
We first found a which is -2.
Then insert any point to find the value of b. In this case, I will insert (1,-2).
-2=-2+b
b=-2+2=0
The linear graph is y=-2x
Answer:
Plants are restrictive to flow of eroding agents, bind soil in their roots.
Step-by-step explanation:
Soil Erosion is the wearing away of the topmost fertile layer of soil. Topsoil gets eroded mainly due to wind, water agents.
Plants help to prevent soil from erosion in following ways :
- Plants act as restriction to the speed of air & water, which are the main soil erosion agents. It also lets rain water get soaked into the ground water.
- Plants roots also bind the soil tightly, & make soil stronger to be eroded by erosive agents - water, air. Eg : Shrubs , trees, grass & ground are important soil erosion preventive plants, because of their extensive root systems.
There is three terms in the expression "n2+6n-3".
In Algebra a term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs, or sometimes by divide.
Answer:
54 miles
Step-by-step explanation:
lets work in steps here:
1 in (24 miles) + 1 in (24 miles) = 2 in OR 48 miles
PLUS
**0.25 in (6 miles)
= 48+6 miles = 54 miles
** you know that 0.25=6 miles because 24/6 is 4. 100/4 is 0.25. simple division.
