Answer:
They're all like terms (x)
-25 - 12x = -(-8x - 6) - 3(5x + 12)
Distributive property.
-25 - 12x = 8x + 6 - 15x - 36
Combine like terms.
-25 - 12x = -7x - 30
Add 12x to both sides.
-25 = 5x - 30
Add 30 to both sides.
5 = 5x
Divide both sides by 5.
x = 1
The x-intersect is 1.
Answer:
Step-by-step explanation:
I’m assuming that the equation is to be written in slope intercept form (y=mx+b), so for this, you want to find the slope and y-intercept. To find the slope, use the equation in picture 1.
0 - 5 = -5
1 - 5 = -4
-5 / -4 = 1.25
So m, or the slope, is equal to 1.25.
To find the y-intercept, make a table like the second picture. Choose one of the ordered pairs as the given. I used 1,0.
0,?
1,0
Now find the change in x, which in this case, is 1. Then set up something like picture three.
1.25/1 = ?/1
?=1.25
Now backtrack to get:
0, -1.25
1, 0
Now we know what is y when x is 0, we know the y intercept and can make the equation:
y = 1.25x - 1.25
The property of soils which depends on the size of particles is Texture.
<h3>Properties of Soil</h3>
The properties of Soil include colour, odor, temperature, and texture as measured by porosity, mouldability and a host of other texture effects.
- It is evident that the texture of soil is dependent on the size of the particles as it affects how packed the particles of the soil is.

y+1=3(x-4)
Multiply the bracket by 3
y+1=3x-12
Follow y=mx+b Move +1 to the other side. Sign changes from +1 to -1
y+1-1=3x-12-1
y=3x-13
Slope=m = 3
b= y-intercept=-13
Answer: Slope=m=3- D.
