Answer:
x+y=5
Step-by-step explanation:
y=-x+5
add x to both sides
x+y=5
1. 130°
I don't remember too many specifics from my past math classes, but I always remembered this because that is an upside-down mirror of the 130° angle.
2. 50°
A straight line is 180°, and 180 - 130 = 50.
Answer:
The y-intercept is 3 aka. (0,3)
Step-by-step explanation:
The slope is 1 (since (6-4)/(3-1)=2/2=1)
y=1x+b
4=1+b
3=b
As shown in the figures given :
For Figure 1 : perimeter = 8 units [As can be seen in the figure]
For figure 2(with 2 octagons) : perimeter = 8 × 2 - 1 = 15 units [since 1 side is common ]
For figure 2(with 3 octagons) : perimeter = 8 × 3 - 2 = 22 units [since 2 sides is common ]
If one more octagon is added
then perimeter = 8 × 4 - 3 = 29 units [since 3 sides will be common ]
