Answer:
I'm pretty sure it's B
Step-by-step explanation:
So sorry if i'm wrong
Since all of the aides are equal as the labeled hash marks say, just count up all of the sides and divide 48 (the perimeter) by that number (8) and you’ll get an answer of 6
Answer:
The answer to your question is letter C
Step-by-step explanation:
To find the slope and the y-intercept solve the equation of the line for y.
4x + 5y = -9
- Substract -4x in both sides
4x - 4x + 5y = -4x - 9
- Simplify
5y = -4x - 9
- Divide by 5 both sides
5y/5 = -4/5x - 9/5
- Simplify
y = -4/5x - 9/5
- Find the slope
m = -4/5
- Find the y-intercept
b = -9/5
So I think the hatch mark on the two sides means the lines are congruent, and it appears that the angles at the top of the triangle are congruent. If so, that would mean that the center line is a bisector of the bottom part of the triangle. This would mean that 16 + x = 8, so x = -8.
