which one do u want help on?
i can help u on all if ud like
Answer:A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x² = −1. Because no real number satisfies this equation, i is called an imaginary number.
Step-by-step explanation:
Answer:
A.) For the first inequality (y<=-3x+5) the ordered pairs are (0,5) and (1,2).
For the second inequality(8x-4y<24) the ordered pairs are (0,-6) and (1,-4).
B. (0,-7) is a solution to both inequalities.
C. (0,6) is not a solution to either inequality.
D. (0,0) is a solution for the first inequality, but not the second inequality.
She spent 25% and had $99 left.
$99 is 75% of the remaining money.
Divide to find the total remaining
99 / 0.75 = $132
Now she put 80% of her total earnings in the bank, this means the remaining amount is 20%.
Divide the remaining amount by 20%:
132 / 0.20 = $660
She earned $660 total.
The answer is A. y = arccos(x)
