There are 3 feet in one yard
The answer is A. A perpendicular equation will have the opposite and reciprocal slope as the original equation.
Once converted to the slope-intercept form of y = mx+b, we find the two equations for A are y = 2x-1 and y = (-1/2)x + 3/2. The opposite reciprocal of the first equation's slope (m in the equation form given) is -1/2, which as you can see if the slope of the other equation.
Answer:
D. -12s squared + 11st - 2t squared
Step-by-step explanation:
FOIL:
-3s(4s) - 3s(-t) + 2t(4s) + 2t(-t)
- 12s² + 3st + 8st - 2t²
Simplify.
- 12s² + 11st - 2t²
Please use " i " to denote "interest."
the formula for simple interest is i = p r t.
Here, i = $160.67 = $2000 (r) (8/12)
Solving for the interest rate, r = ($169.67)(12/8)/ $2000 = 0.127, or 12.7%
