Answer:
B. 4
Step-by-step explanation:
Determine the constant of variation for the direct variation given.
(0, 0), (3, 12), (9, 36)
A. 3
B. 4
C.12
Direct variation is given by:
y = kx
Where,
k = constant of variation
(3, 12)
x = 3; y = 12
y = kx
12 = k*3
12 = 3k
k = 12 / 3
k = 4
(9, 36)
x = 9; y = 36
y = kx
36 = k * 9
36 = 9k
k = 36 / 9
= 4
k = 4
Constant of the variation = 4
Answer:
No. A = 32 square units B= 42 square units
Explanation:
When finding the area of composite figures, add the area of each figure.
Answer:
Step-by-step explanation:
Simply use the fact that the change in x squared + the change in y squared = the distance squared. (The Pythagorean Theorem)
1^2 + 4^2 = d^2
1 + 16 = d^2
17 = d^2
d = √17

The unit of time that will make the statement true is "day"
<h3>What unit of time will make the statement true?</h3>
The conversion equation is given as:
Seconds + Seconds/? * day = seconds
Represent the blank with a variable (x)
So, we have:
Seconds + Seconds/x * day = seconds
Subtract "seconds" from both sides of the equation
So, we have:
Seconds/x * day = seconds
Divide both sides of the equation by "seconds"
So, we have:
1/x * day = 1
Multiply both sides by x
x= day
Hence, the unit of time that will make the statement true is "day"

<h3>
Answer: 2x</h3>
Explanation:
Each person is x years old. Adding those unknown ages gets us x+x = 2x
We can think of it like x being one box, so x+x represents having two boxes which shortens to 2x.
