Answer:
p=4
Step-by-step explanation:
first change all the addition signs in to minus if the numbers are negative. ex. p+-8 = p-8.
So the equation equals to -2(p-8)-2=6.
Next +2 to both sides to cancel out the -2 and you get -2(p-8)=8
Divide both sides by -2 and you get (p-8)=-4. At this point you can remove the parenthesis. So the equation is p-8=-4
Finally +8 to both sides and you get p=4
Answer:
80
Step-by-step explanation:
20% of 400 is
= 20/100 * 400
= 80
A nonagon is which all sides are equal and all angles are equal is a regular nonagon. each angle of a regular nonagon is of 140 degrees.
Answer:
y = (1/3)x + 7
Step-by-step explanation:
The slope of a line perpendicular to the given line y = -3x - 2 would have to be the negative reciprocal of the slope of the given line:
or, in other words,
the negative reciprocal of -3. That would be +1/3.
Starting with the slope-intercept form of the equation of a straight line, we have:
y = mx + b.
We substitute the coordinates of the given point, (-9,4), and the slope +1/3:
4 = (1/3)(-9) + b.
This simplifies to
4 = -3 + b, from which it can be easily seen that b = 7.
The desired line is y = (1/3)x + 7.
