Answer:
see explanation
Step-by-step explanation:
The 3 arcs AB, BC and CA form the circle and equal 360°, thus
2x + 3x + 4x = 360
9x = 360 ( divide both sides by 9 )
x = 40
-----------------------------------
The inscribed ∠ 1 is half the measure of its intercepted arc, that is
∠ 1 = 0.5 × arc BC = 0.5 × 3x = 0.5 × 120° = 60°
The inscribed ∠ 2 is also half its intercepted arc
∠ 2 = 0.5 × BC = 0.5 × 120° = 60°
The angle at the centre ∠ 3 is twice the angle at the circumference ∠ 1
∠ 3 = 2 × ∠ 1 = 2 × 60° = 120°
The triangle OBC is isosceles ( OB = OC, the radii of the circle )
Thus the base angles are congruent, thus
∠ 4 = =
= 30°
y = mx + b
To find the slope(m), you use the slope formula:
You plug in the points into the equation.
The slope is 0
y = 0x + b
Any number multiplied by 0 is 0. So:
y = b
To find b, you plug in the y value of either of the points.
-4 = b
Your equation is:
y = -4 (This is a horizontal line)
Answer:
Step-by-step explanation:
(6, 4)
x = 6 and y = 4
y > -1/2x + 7
Plug in the values to check if it is true.
4 > -1/2(6) + 7
4 > -3 + 7
4 > 4
This statement is false.
(6, 4) lies on the line.
Let's see what to do buddy...
