Answer:
B. No
Step-by-step explanation:
In order to see if (4, 2) is a solution, we have to plug 4 in for x and 2 in for y in the equations. If it's a true statement, then we know that the point is a solution.
One of the equations is y = 3x + 4. Plug in 4 for x and 2 for y:
y =? 3x + 4
2 =? 3 * 4 + 4
2 =? 12 + 4
2 ≠ 16
Thus, we know that (4, 2) is not a solution and the answer is B.

You should indicate which type of expression are you expecting.
But intuitively, x^2 + 16 = x^4 + 4^2 = (x+4)^2 - 8x
Answer:
3*w
Step-by-step explanation:
Kamilah now weighs the triple of what she weighed on her first birthday. That means we need to multiply the first weight by 3. As the first weight is w, she now weighs 3*w.
Another possible expression is to sum 3 times w, that is w + w + w (it's equal to 3*w).
Answer: 5/3
Step-by-step explanation:
(3/5)x = 12
(5/3)(3/5)x = (5/3)12
x = 20
Therefore, choose Option D: 5/3

The unit rate is 0.25 kilograms per year.
Step-by-step explanation:
Lets define unit rate first
Unit rate is the change in quantity per unit time.
Given
Weight = w = 5 kg
Time = t = 20 years
So,
Hence,
The unit rate is 0.25 kilograms per year.
