Answer:
30 ≥
Step-by-step explanation:
6 ≥ 1/2x + 21
-6 -6
1/2x ≥ 15
15/1 x 2/1 = 30/1
answer: 30
you keep the sign the same because you only flip the sign if you multiply or divide by a negative number
Answer:
The answer to this problem is 3/4
Step-by-step explanation:
To answer this problem, you need to divide 4 1/2 by 6. After you did that, your answer will be how many cups of chocolate chips there are in a serving, to check your answer, you can multiply 3/4 by 6 (Sorry if this is incorrect, im pretty sure it is correct) :)
Answer:
j= -18
Step-by-step explanation:
Answer:
The domain of the function should be:
'x greater than or equal to negative -5'.
Hence, option A is true.
Step-by-step explanation:
Given the expression
![2\sqrt{x-5}](https://tex.z-dn.net/?f=2%5Csqrt%7Bx-5%7D)
The domain of a function is the set of input or arguments for which the function is real and defined
We know that the value, inside the radicand, is the number found inside a radical symbol which must be greater than 0, otherwise, it would make the function undefined,
i.e.
x-5 ≥ 0
x ≥ 5
In other words, the domain of the function should be:
'x greater than or equal to negative -5'.
Therefore, the domain of the function:
x ≥ 5
![\mathrm{Domain\:of\:}\:2\sqrt{x-5}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:5\:\\ \:\mathrm{Interval\:Notation:}&\:[5,\:\infty \:)\end{bmatrix}](https://tex.z-dn.net/?f=%5Cmathrm%7BDomain%5C%3Aof%5C%3A%7D%5C%3A2%5Csqrt%7Bx-5%7D%5C%3A%3A%5Cquad%20%5Cbegin%7Bbmatrix%7D%5Cmathrm%7BSolution%3A%7D%5C%3A%26%5C%3Ax%5Cge%20%5C%3A5%5C%3A%5C%5C%20%5C%3A%5Cmathrm%7BInterval%5C%3ANotation%3A%7D%26%5C%3A%5B5%2C%5C%3A%5Cinfty%20%5C%3A%29%5Cend%7Bbmatrix%7D)
Hence, option A is true.
According to the given expressions, there was used the multiplication property for inequalities because there's being multiplied the number 61 on both sides.
