I think its C because you just have to follow the expressions pattern i hope this helps good luck!!
1 kg = 1000 g....so 2.5 kg = (2.5 * 1000) = 2500 grams
it cooks 30 minutes per 500 g.....2500/500 = 5...so there are 5 thirty minute periods ....(5 * 30) = 150 minutes....plus the extra 20 minutes....(150 + 20) = 170 minutes....so your answerr is 2 hrs 50 minutes
Option B,C and D are correct.
Step-by-step explanation:
We need to determine which statements are true about ![2gh-(3+7)+\frac{x}{4}](https://tex.z-dn.net/?f=2gh-%283%2B7%29%2B%5Cfrac%7Bx%7D%7B4%7D)
Checking the options:
The term x/4 is quotient of 2 variables is not true.
2gh-(3+7) is the difference of two terms is true
Co-efficient of the expression are 2 and 1/4 is true because, co-efficient are terms that comes with variables.
The expression 3+7 is sum of two numbers is also true.
Option B,C and D are correct.

Answer: (A)
Step by Step
9/2 is rise over run so your 9 would be on the y axis representing the height and your 2 would be on the x axis representing age(yrs)
Answer:
D. ![x\geq 0](https://tex.z-dn.net/?f=x%5Cgeq%200)
Step-by-step explanation:
In order to answer this question we need to know the definition of the domain. The domain of a function is the complete set of possible values of the independent variable ("x"). In our case we can look at the function and cross out option "A" because the function has no point with a negative "x" value. Option "B" can be also crossed out because it states that "x" values can not go above 3 but by looking at the function we can see multiple point with "x" values larger then 3. Option "C" can also be crossed out because their is not point on the function that would have a negative "x" value which contradicts the statement about all numbers. And finally we are left with "D" and we know it is the right answer since the function has a point with "x" value being equal to 0 and the all other points have the "x" value greater then 0, which is exactly what option "D" states.
