Answer:
Step-by-step explanation:
1)a ) Let the constant proportionality =k
Direct proportion.So, y = kx
Plugin y = 6 and x =2 and find k
6 = k*2
6/2 = k
k = 3
Constant proportionality = 3
b) y = 3x
When x = 7 ; y = 3*7 = 21
y = 21
c)When x = 9,
y = 3*9
y = 27
d) When y = 9,
9 = 3*x
9/3 = x
x = 3
e)when y = 30
30 = 3*x
30/3 =x
x = 10
3) y is inversely proportion to x³
b) when x = 4
c) When x = 6
d) When y = 24
Answer:
Yes they equal eachother beacuse the math teacher told me that they do
Step-by-step explanation:
so first you see pattern look up lok down then answer the question
Answer:
This is ur ans
Step-by-step explanation:
a.y=5x or x=y/5
b.y=60
y/x=5
y/12=5
y=60
The actual is 60 feet long, the drawing is only 1 foot long. So the scale factor must be 1/60. You know that the scale factor has to be less than one in this case because you're going from a bigger measurement to a smaller measurement(60 to 1).
Answer:
The relationship ⇒ <u>25x + 40y = 12,250</u>
Step-by-step explanation:
The number of student memberships = x
The number of adult memberships = y
The monthly membership fee for a student = $25
The monthly membership fee for an adult = $40
The total fee = 25x + 40y
Al's Athletic Club receives $12,250 in membership fees for the month of January.
So, the relationship between x and y is:
<u>25x + 40y = 12,250</u>
