Answer:15
Step-by-step explanation:
If 85% pass then 15% failed and 15% of 1,200 is 180 so 180 people failed.
Answer:
y=-1/4x+8
Step-by-step explanation:
To find the equation of a line that is perpendicular to a line, you would take the opposite reciprocal of the slope.
Before that, we need to change the equation into slope-intercept form.
-4x+y=10
y=4x+10
The opposite reciprocal of the slope is -1/4.
Now, let's use the point-slope formula to find our equation of the line that passes through (-4,9).
y-y1=m(x-x1)
y-9=-1/4(x-(-4))
y-9=-1/4x-1
y=-1/4x+8
7%, 13%, 0.15, 4/25, 21/100, 0.28
A stop sign has 8 sides and all angles are the same, so it is a regular octagon.
