Answer:
BC is equal to 7
Step-by-step explanation:
18 = 2x + 4
18 - 4 = 14
14 = 2x
14/2 = 7
7 = x
<span>3 times the complement of an angle is 30 more than the supplement of the original angle.
so if the angle is x then its complement is 90-x & supplement is 180-x
so 3(90-x)=(180-x)+30
or 270-3x=210-x
or 3x-x=270-210
or 2x=60
or x=30 the original angle

Answer:
y ≤ -4x+25
Step-by-step explanation:
First we need to figure out the equation for the line
The y intercept is 25
Next figure out the slope
slope = (y2-y1)/((x2-x1)
= (49-25)/(-6-0)
= 24/-6
= -4
The equation for a line in slope intercept form is y = mx+b
y = -4x+25
This is a solid line so our inequality will have an equals in it.
It is shaded below, so y is less than.
If it was shaded above, y would be greater than
y ≤ -4x+25
20+20-3-3-4 the 3 3 and 4 are beagative numbers
