Answer:
x = 4.75 or 19/4 or 4 and 3/4
Step-by-step explanation:
10 - 4x = -9
-10 -10
-4x = -19
---- -----
-4 -4
x = 4.75 or 19/4 or 4 and 3/4
The best way to answer this item is to use the Substitution method. Substitute the value of y from the first equation to the y of the second equation such that the second equation becomes,
-4x + 3(x - 4) = -3
Simplifying the equation,
-x = 9
Dividing both sides by -1 gives an answer of,
<em>x = -9</em>
Then, substitute the value of x in the first equation.
y = -9 - 4
<em> y = -13</em>
The answer to this item is letter B.
The imaginary unit, i, which represents the square root of -1 raised to power 4 is 1
The organized steps are;
- Choice F; Therefore, Sebastian is incorrect
Reason:
The given expression Sebastian simplified is; -4·i²¹²
The result Sebastian got = 4
The organized steps are presented as follows;
We have that 212 ÷ 4 = 3
Since i⁴ = 1
Then -4·1 = -4
Therefore, Sebastian is incorrect
The order of the steps are therefore;
Given -4·i²¹²
Choice E; Since i⁴ = 1
Choice B; Then -4·1 = -4
Choice F; Therefore, Sebastian is incorrect
