Answer:
The perpendicular line would be y = -3x - 7
Step-by-step explanation:
To find the equation of the line, we first need to solve the original line for y.
-x + 3y = 9
3y = x + 9
y = 1/3x + 3
Now we know the slope of the original line to be 1/3. Since perpendicular lines have opposite and reciprocal slope, we know the new line to have a slope of -3. We can then use that along with the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 2 = -3(x + 3)
y - 2 = -3x - 9
y = -3x - 7
A ) 5x^3 - 6x^4
B ) 11x^4 - 13x^3
C ) 14^x3 - 2x^4
D ) 2x^4 - 12x^3
E) 5x^4 - 3x^3
I believe this is all right!
Answer:
Percent
Step-by-step explanation:
the amount of decrease divided by the original amount times 100 equals <u><em>percent of decrease</em></u>
The cost of 85 shirts is 400+7.5*85=1037.5
The average per shirt is 1037.5/85=12.206
I'm pretty sure it would be 95.40. Because 90 x 6%= 5.40 add that to 90
