Answer:
5-46i
Step-by-step explanation:
1. Multiply (10-4i) and (4-5i), I recomnd using foil:
40-50i-16+20i^2 + (-15+20i)
2. Remove the parenthesis around -15+20i
*we can do this since there is a "+":
40-50i-16+20i^2 + (-15)+20
3. Simplify i^2
* i^2 is -1 by textbook defination:
40-50i-16+20(-1) + (-15)+20
4. Simplify
40-50i-16-20 + (-15)+20
6. Combine like terms:
-5-50i-16i+20i
5-46i
And the problem is done

Answer:
Equation: 2x + 5 + 6x + 15 = 92
Solution: x = 9
m∠A =23° m∠B = 69°
Step-by-step explanation:
measure of ∠B = 3(2x + 5) = 6x + 15
The sum of the angles = 92 = 2x + 5 + 6x + 15
92 = 8x + 20
72 = 8x
x = 9
m∠A = 2(9) + 5 = 18 + 5 = 23
m∠B = 6(9) + 15 = 54 + 15 = 69
Check: 23 + 69 = 92 and 23(3) = 69
Answer: True
Step-by-step explanation:
Let p= Students who do well in course do not skip class
q= Student who study hard do well in course
So p^q= Student who study hard and who do well in course do not skip class.
If p= true and q=true then p^q= true by discrete maths.
Answer:
g(x) = -x^2 - 4
Step-by-step explanation:
f(x) = x^2
To flip the graph, you need the negative of the right side,
y = -x^2
This is a parabola that opens downward, but the vertex is at (0, 0).
Now you need to translate the graph 4 units down, so subtract 4 from -x^2.
g(x) = -x^2 - 4
