Answer:
y=x-3
Step-by-step explanation:
slope=4+2/-5-1=-1
perpendicular slope= negative reciprical=1
y=x+b
midpoint on perpendicular bisector= (-5+1/2, 4-2/2)=(-2,1)
substitution-2=1+b, b=-3
y=x-3
Answer:
No, it is positive.
Step-by-step explanation:
Step-by-step explanation:
In isoceles triangle two sides are equal and two angles are equal.
Then,
∠R = ∠T = (5x-40)°
Then,
∠RTS + ∠STU = 180° (bcoz it lies on a straight line)
(5x-40) ° + 5x = 180°
10x = 220°
x = 22°
Therefore,
Option A is correct✔
Answer:
x = 117
Step-by-step explanation:
Given
11 - = 0 ( subtract 11 from both sides )
- = - 11 ( square both sides )
(- )² = (- 11)²
x + 4 = 121 ( subtract 4 from both sides )
x = 117
Answer:
The solution is B) (2, ).
Step-by-step explanation:
This system of equations can be solved by elimination, where we add the two equations together to eliminate one of the variables and solve for the remaining variable:
x + 2y = 3
<u>3x - 2y = 5</u>
4x = 8 or x = 2
To solve for 'y', plug in the value of x: 2 + 2y = 3 or 2y = 1 or y =
Putting the values into the point (x, y) = (2, )
