Answer:
Friend is not correct.
Step-by-step explanation:
<em>The complete question with image is attached.</em>
We need to find the angle and the point (0.8), or the angle created between the two lines.
First we need to find slope (m) of both the lines.
The slope (m) is change in y coordinates divided by change in x coordinates. Or
<u>Slope of line above:</u>
<u>Slope of below line:</u>
The formula to find angle between two lines is:
Where m_1 = -2 and m_2 = 2
Plugging in the values, we get:
Angle = 53
Hence, your friend IS NOT correct.
The slope form: y = mx + b
We have:
3x - 6y - 2 = 0 |add 6y to both sides
3x - 2 = 6y |divide both sides by 6
3x/6 - 2/6 = 6y/6
x/2 - 1/3 = y
y = 1/2 x - 1/3
Use the distributive property
(4x + 2)3
Distribute.
3 * 4x = 12x
3 * 2 = 6
<u>Answer</u>
12x + 6

Answer:
- -3/4a^3b^2
- 3.2·10^-1
- -0.1a^(n+1)
Step-by-step explanation:
To find the cube root, divide all of the exponents by 3. For a cube root, the sign is unchanged.
A) ∛(-27/64a^9b^6) = -∛(3^3/4^3·a^9·b^6) = -3/4a^3b^2
__
B) 9.6×10^-8 ÷ (3×10^-7) = (9.6/3)×10^(-8-(-7)) = 3.2×10^-1
__
C) ∛(-0.001a^(3n+3)) = -∛(0.1^3·a^(3n+3)) = -0.1a^(n+1)
