8.9-3.3j=-2.2j+2.3
add 3.3j to both sides
8.9=1.1j+2.3
subtract 2.3 from both sides
6.6=1.1j
divide both sides by 1.1
6=j
Answer:
1. Evaluate 3y - 4 for y =5
3*(5)-4=15-4=11
2. 65 + x = 99 x = ?
65+x=99
x=99-65
x=34
3. Find the product. 38.7 *21
38.7*21=812.7
4. Which value satisfies the equation? 9x + 3 = 30
The right value for x would be:
9x+3=30
9x=30-3
9x=27
x=27/9=3
Step-by-step explanation:
The square root of 5 is 2.2 and 4 times the square root of 10 is 100
<h3><u>
Answer:</u></h3>
Option: C is the correct answer.
c) the coefficient of x is positive
<h3><u>
Step-by-step explanation:</u></h3>
We know that graph of a line goes up and to the right when the coefficient of x is positive.
Since we know that when a line goes up and to the right this means that the line is increasing and hence we will get a positive slope of the line and we know that the slope intercept of a line is given as:

as m is positive this means that:
the coefficient of x is positive.
Hence, the correct answer is:
c) the coefficient of x is positive
