8 - (-4) [2 negatives become a positive]
8 + 4 = 12
A.) - 8 + 4 = -4
B.) -8 + (-4) = -12
C.) 8 + (-4) = 4
D.) 4 - (-8) = 4 + 8 = 12
Your answer is D
which of the following is the conjugate of a complex number with 2 as the real part and -8i as the imaginary part
Answer:
1) Slope: 3; y-intercept: -7
2) Slope: 2/3; y-intercept: 1
Step-by-step explanation:
y = mx + b; m is slope and b is y-intercept
1. y = 3x - 7
The equation is already in slope-intercept form, so you can find the slope and intercept.
Slope: 3
y-intercept: -7
2. y - 1 = 2/3x
For this one, you have to convert this into slope-intercept form (solving for y)
y - 1 = 2/3x
Add 1 to both sides
y - 1 + 1 = 2/3x + 1
y = 2/3x + 1
Now that the equation is in slope-intercept form, you can get the slope and y-intercept.
Slope: 2/3
y-intercept: 1
-8645 is not the opposite to -8645. 8645 is the correct opposite to -8645
Answer: 30
Step-by-step explanation:5(Z+4) + 5(2-Z).
Open the brackets by multiplying true by the number out of the bracket.
5Z + 20 + 10 - 5Z
Now, collect like terms, we have.
5Z - 5Z + 20 + 10. Now we have
0 + 30 = 30//
