The answer to your question is the last one through the method of competing the square
The answer is "Point B is at (-8, -7)". let's remember that -8 represents the x-axis, and -7 represents the y-axis.
let me know if that helps !
Answer:
Step-by-step explanation:
Slope-intercept formula requires us to isolate the y variable. We can do this in just a couple of steps.
1) Move 5x from the left to the right side by subtracting 5x from both sides. This cancels out the 5x on the left side, and remember, what we do to one side we must do to the other to keep the equation balanced.
2) Divide both sides by 6. Again, we are cancelling out the 6 on the left but we must also divide on the right. This would mean dividing -5 and 42 by 6 to get:
We have the triangle 30° - 60° - 90°.
The lenght of the sides are in proportion:
