Answer:
I think its C
Step-by-step explanation:
I think it is that because it says reflection so you just flip the negative and the positive for both numbers so it's basically the opposite. not 100 percent tho.
Answer:
The geometric mean of 6 and 16 =
Step-by-step explanation:
The Geometric Mean is basically a special type of average which can be determined
- by multiply the numbers together and subsequently taking a square root in case there are two numbers; but we take cube root in case there three numbers etc.
So, lets take the geometric mean of 6 and 16
Considering the number
6 and 16
- Step 1: Multiply the numbers i.e. 6 × 16 = 96
Step 2: As there are two number, so just take the square root i.e.
In other words:
Geometric Mean of 6 and 16:
Therefore, the geometric mean of 6 and 16 =
Answer:
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
Step-by-step explanation:
Solve the following system by substitution.
2x – 3y = –2
4x + y = 24
The idea here is to solve one of the equations for one of the variables, and plug this into the other equation. It does not matter which equation or which variable you pick. There is no right or wrong choice; the answer will be the same, regardless. But — some choices may be better than others.
For instance, in this case, can you see that it would probably be simplest to solve the second equation for "y =", since there is already a y floating around loose in the middle there? I could solve the first equation for either variable, but I'd get fractions, and solving the second equation for x would also give me fractions. It wouldn't be "wrong" to make a different choice, but it would probably be more difficult. Being lazy, I'll solve the second equation for y:
4x + y = 24
y = –4x + 24
Now I'll plug this in ("substitute it") for "y" in the first equation, and solve for x:
2x – 3(–4x + 24) = –2
2x + 12x – 72 = –2
14x = 70
x = 5
Answer:
12.241km
Step-by-step explanation:
18.75 - 6.509 =12.241
The equivalent expressions are 3(6x - 3) = 72 and 18x - 9 = 72
<h3>Equations and expressions</h3>
Given the equation below as shown;
3/5(30x - 15) = 72
Expand
3/5(30x) - 3/5(15) = 72
90x/5 - 15/5 = 72
3(6x - 3) = 72
Expand
18x - 9 = 72
Hence the equivalent expressions are 3(6x - 3) = 72 and 18x - 9 = 72
