25 + 35 = 60
300/60 = 5
the answer is 5 packets
First, let's re-arrange to slope-intercept form.
x + 8y = 27
Subtract 'x' to both sides:
8y = -x + 27
Divide 8 to both sides:
y = -1/8x + 3.375
So the slope of this line is -1/8, to find the slope that is perpendicular to this, we multiply it by -1 and flip it. -1/8 * -1 = 1/8, flipping it will give us 8/1 or 8.
So the slope of the perpendicular line will be 8.
Now we can plug this into point-slope form along with the point given.
y - y1 = m(x - x1)
y - 5 = 8(x + 5)
y - 5 = 8x + 40
y = 8x + 45
They are all larger than 90 degrees, and in a triangle they would all be obtuse angles.
Answer: 0
Step-by-step explanation: 8-8 equals... ZERO GOOD JOB GUYS!
You need to expand the brackets eg.
(w-9)8 basically means 8 x (w-9) = 8w-72
