your answer will be 2.75
- 3x + 2x + 5 + 5x + 15 = 180 [angles on a line add to 180 degrees]
- 10x + 20 = 180 [combine like terms]
- 10x = 160 [subtract 20 from both sides]
- x = 16 [divide both sides by 10]
Arc AB measures 3(16) = 48 degrees.
Arc BC measures 2(16) + 5 = 41 degrees.
Answer: Therefore, the x-intercept of the line is 0
A line with slope 2/3 contains the point P(-18, -12). What is the x intercept of the line?
Step-by-step explanation:
Given;
Slope m = 2/3
Straight line equation is given as
y = mx+c
Where m = slope and c = intercept on y axis
For this case,
y = 2/3x + c .....1
At point (-18,-12), Eqn 1 becomes;
-12 = 2/3(-18) + c
-12 = -12 + c
c = 0
The straight line equation becomes
y = 2/3x + 0
Therefore at y = 0 the value of x = 0
Therefore the intercept is at (0,0)
Therefore, the x-intercept of the line is 0
36= p x 13

Vote my answer the brainyest if it was helpful!!!
the distance from the origin is 5, so
sqrt(x²+y²)=5
x²+y²=25
substitue y=x²
y+y²=25
y²+y-25=0
solve using calculator or the formula
to get
y =( -1+sqrt(1+4*25))/2
or y = (-1-sqrt(1+4*25))/2
the second solution is rejected because a square cannot be negative
the value of x is the positive or negative (sqrt... or -sqrt...) or y
