Answer:
D) -5/3
Step-by-step explanation:
(Points on the graph): (6, 10) and (12, 0)
Slope:
m=(y2-y1)/(x2-x1)
m=(0-10)/(12-6)
m=(-10)/6
m = -5/3
We know: The sum of the measures of the angles of a triangle is equal 180°.
We have: m∠A =65°, m∠B = (3x - 10)° and m∠C = (2x)°.
The equation:
65 + (3x - 10) + 2x = 180
(3x + 2x) + (65 - 10) = 180
5x + 55 = 180 <em>subtract 55 from both sides</em>
5x = 125 <em>divide both sides by 5</em>
x = 25
m∠B = (3x - 10)° → m∠B = (3 · 25 - 10)° = (75 - 10)° = 65°
m∠C = (2x)° → m∠C = (2 · 25)° = 50°
<h3>Answer: x = 25, m∠B = 65°, m∠C = 50°</h3>
Answer: is in the picture
A and D because the text states the moon rises from the east and sets in the west, but it can rise earlier in the day when the sun is brighter than the moon so you can't see the moon.
Answer:
2=1/4(4+b)
Step-by-step explanation:
(0,1), (4,2)
first, find the slope
slope formula- (y2-y1)/(x2-x1)
plug in the coordinates
(2-1)/(4-0)
subtract
1/4
slope=1/4
slope intercept form- y=mx+b
choose one of the coordinates to plug in
(4,2)
plug it in
2=1/4(4+b)
