Answer: 12 pounds.
Step-by-step explanation:
To solve this question, we'll use the direct proportion which is.
y = kx
Where,
y = weight on moon = 48 pounds
x = weight on Earth = 300 pounds
k = Unknown
y = kx
48 = 300k
k = 48/300
k = 0.16
The weight that a 75 pound object on Earth would weigh on the moon will be:
y = kx
where,
y = weight on moon = Unknown
k = 0.16
x = weight on Earth = 75 pounds
y = kx
y= 0.16 × 75
y = 12 pounds
The weight on the moon will be 12 pounds.
Answer:
2(7b+5)
Step-by-step explanation:
Hi!
The answer is B. Linear function.
A linear function is when the change in <em>y </em>and <em>x</em><em> </em>is constant. For example, let's make some <em>x</em> and <em>y</em> values.
x 1, 2, 3, 4, 5
y 2, 4, 6, 8, 10
When <em>x</em> increases by 1, <em>y</em> increases by 2. The change in <em>x</em> and <em>y </em>is constant, therefore, that is a linear function.
x 6, 9, 13, 26
y 3, 5, 10, 11
There is no pattern in those numbers, therefore this is not a linear function.
Hope this helps! :)
