Answer:
Step-by-step explanation:
<u>As per the question we have:</u>
- The y - intercept is b = -1
- The slope has same angle with x- and y - axis.
This can be a function with the slope of m = 1 or m = - 1 as these lines must be perpendicular to each other and make 90°/2 = 45° or 45° + 90° = 135° angle with the x- or y- axis.
<u>So the lines could be:</u>
So sides are x, 2x, 3x. Perimeter would be 6x. So the perimeter is two times the longest side.
Answer:
just add all the sides. to slove

Hello!
~~~~~~~~~~~~~~~``
Simplifying
2x + 3y = 45
Solving
2x + 3y = 45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3y' to each side of the equation.
2x + 3y + -3y = 45 + -3y
Combine like terms: 3y + -3y = 0
2x + 0 = 45 + -3y
2x = 45 + -3y
Divide each side by '2'.
x = 22.5 + -1.5y
Simplifying
x = 22.5 + -1.5y
Hope this helped you! Brainliest would be nice.
