Answer:
and
do not lie on the line
Step-by-step explanation:
Given

Required
Determine which points that are not on the line
First, we need to determine the slope (m) of the line:

Where


So;



Next, we determine the line equation using:

Where


becomes


To determine which point is on the line, we simply plug in the values of x to in the equation check.

Answer:
x = 12
(2x + 1)° = 25°
(5x + 5)° = 65°
Step-by-step explanation:
By the property of a triangle,
Sum of all angles of a triangle is 180°
In the given right triangle,
(2x + 1)° + 90° + (5x + 5)°= 180°
7x + 96 = 180
7x = 180 - 96
x = 
x = 12
Angle (2x + 1)° = 2(12) + 1 = 25°
Angle (5x + 5)° = 5(12) + 5 = 65°
Therefore, all three angles of the right triangle are 25°, 90° and 65°.
X= -14/3 that's the answer there bud i need to make this 20 caracters longs so yeah x=-14/3
Answer: 
Step-by-step explanation:
Remembert that, by definition:
→ 
Then, you can rewrite
in exponential form:

Now you can solve for the variable "x":
Add 6 to both sides of the equation:


And finally you must divide both sides of the equation by 2, then:
