Answer: √9 = 3
Verification:
= 3 * 3
=> 9
Answer:
Step-by-step explanation:
The equation for slope is:
We can substitute the given coordinates into the equation:
The slope is -3
The equation for a line is:
m: slope
b: y-intercept
x, y: (x, y) coordinate pair
Now, plug in the slope and one of the (x, y) coordinate pairs to solve for the y-intercept.
Therefore the equation is:
Step-by-step explanation:
Let x be the money made in sales. Let y be the money made in commissions.
First, convert 2.5% to a decimal.
2.5% = 0.025
Equation:
0.025x = y
Robert:
0.025(8850) = y
y = $221.25
Francisca:
0.025x = 279
x = 279/0.025
x = $11,160
Answer:
7 - 3 i
Step-by-step explanation:
Simplifying
(3 + -2i) + (4 + -5i) = 0
Remove parenthesis around (3 + -2i)
3 + -2i + (4 + -5i) = 0
Remove parenthesis around (4 + -5i)
3 + -2i + 4 + -5i = 0
Reorder the terms:
3 + 4 + -2i + -5i = 0
Combine like terms: 3 + 4 = 7
7 + -2i + -5i = 0
Combine like terms: -2i + -5i = -7i
7 + -7i = 0
Solving
7 + -7i = 0
Solving for variable 'i'.
Move all terms containing i to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + -7i = 0 + -7
Combine like terms: 7 + -7 = 0
0 + -7i = 0 + -7
-7i = 0 + -7
Combine like terms: 0 + -7 = -7
-7i = -7
Divide each side by '-7'.
i = 1
Simplifying
i = 1
