With the distributive property, you multiply whatever is one the outside of the parenthesis, by each term on the inside.
6a + 6b
Also, whats with the image? Lol.
We know that
<span>a) the slope-intercept form of the line---------------> y=mx+b
b) </span><span>if two lines are parallel both have the same slope
</span>then
<span>passes through the point (1,0) and is parallel to x-y=7
Step 1
Find the slope
</span>x-y=7------------> y=x-7------------> m=1
Step 2
Find the slope-intercept form of the line---> y=mx+b
point (1,0) m=1
0=(1)*(1)+b------> b=-1
y=(1)*x-1--------> y=x-1
the answer is
y=x-1
using a graph tool
see the attached figure
Answer: B
Explanation:
Equation of line y=mx+b
m = y2-y1/x2-x1 = 2-(-2)/1-(-1) = 4/2 = 2
b = (0,0)
y = 2x+0
y=2x
Answer: 1 m/s to the left
Step-by-step explanation: Considering momentun conservation, this is as follow:
PA+PB= Constant
PA= 2 Kg * 4 m/s to the rigth
PB= 5 Kg* 3 m/s to the left
after collision the two mass go together so the PA+B = Vfinal (mA+mB)= Vfinal (2 kg +5 kg), the momentum conservation is then
PA-PB=8-15=-7 = Vfinal (7kg)
Vfinal= -7/7 m/s=-1 m/s
Answer:
Simplifying
12a + b + 3a + 5b = 0
Reorder the terms:
12a + 3a + b + 5b = 0
Combine like terms: 12a + 3a = 15a
15a + b + 5b = 0
Combine like terms: b + 5b = 6b
15a + 6b = 0
Solving
15a + 6b = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-6b' to each side of the equation.
15a + 6b + -6b = 0 + -6b
Combine like terms: 6b + -6b = 0
15a + 0 = 0 + -6b
15a = 0 + -6b
Remove the zero:
15a = -6b
Divide each side by '15'.
a = -0.4b
Simplifying
a = -0.4b
