Answer:
Step-by-step explanation:
A rectangle has same opposite sides and 4 right angles as property of a rectangle.
The photo frame has different diagonal lengths
It makes opposite sides different, therefore it is not a rectangle
<u>Given angles (x - 20) and (x + 40) are consecutive interior angles which add up to 180°</u>
- x - 20° + x + 40° = 180°
- 2x + 20° = 180°
- 2x = 160°
- x = 80°
<h3>
Answer: y = (-1/2)x - 9/2</h3>
Slope = -1/2
Y intercept = -9/2
=====================================================
Work Shown:
2x + 4y = -18
2(x+2y) = -18 .... factor out 2
x+2y = -18/2 .... divide both sides by 2
x+2y = -9
2y = -9-x .... subtract x from both sides
2y = -x-9
y = (-x-9)/2 ... divide both sides by 2
y = (-x/2) - (9/2) ... break up the fraction
y = (-1/2)x - 9/2
The last equation is in slope intercept form y = mx+b with m = -1/2 as the slope and b = -9/2 as the y intercept.
Answer:
B. tan (-180°) = 0
Step-by-step explanation:
Tangent is the ratio of opposite to adjacent to an angle
From the unit circle; the opposite to our angle -180° is 0
The adjacent along the x-axis is 1
Therefore;
Tan (-180°) = 0/1
= 0
Therefore; Tan (-180°) is 0
3 was the mode of the number of rides the people went that day because it appeared 3 times than the other numbers 0,1, and 2 which appeared only 2 times in the chart
Hope this helps!:)
