ANSWER: you have to figure out if it’s proportional
Step-by-step explanation:
You can do this by:
Seeing if it increases, has a slope, if it has a curve or straight line (straight line, proportional)
Answer:
90 miles
Step-by-step explanation:
Let ori. speed = z
distance = speed × time
= z × 2
= 2z miles
distance = (z - 15) × 3
= (3z - 45)miles
2z = 3z - 45
z = 45mph
distance = 45 × 2
= 90 miles
distance = (45-15) × 3
= 90 miles
(Correct me if i am wrong)
Answer:
Octagon
Step-by-step explanation:
Sum of interior angles = 3*360 = 1080
sum of interior angles, is also, s = (n-2)180
From that,
n-2)180 = 1080
n-2 = 1080/180
n = 6 + 2
n = 8
Therefore, the figure is an 8 sided polygon or an octagon
A positive correlation implies a positive slope
Choose two points at gridline intersections and find the vertical and horizontal distance between them. The put the vertical distance over the horizontal distance (rise/run), and you have your slope
