Y = mx + b....for b
subtract mx from both sides
y - mx = b <==
Answer:
Step-by-step explanation:
first multiply 1 with 2+5i then multiply 2i with 2+5i and you will get
2+5i+4i+10i^2
then in the next step add 4i and 5i you will get 9i
in the next step put i^2=-1 and you will get -10
in the last step just substract 2-10 you will get -8 and 9i
and your answer will be -8+9i
Answer:
Step-by-step explanation:
- The two given angles are complementary, it means they add to 90°
<u>Find x:</u>
- 2x + 10 + x + 8 = 90
- 3x + 18 = 90
- 3x = 72
- x = 24
<u>Find Y:</u>
- m∠Y = x + 8 = 24 + 8 = 32°
Answer:
So we will be saving a total of $0.7 at new rate
Step-by-step explanation:
Given:
Original price =$ 0.69
New price = $ 2.75 per 5 switches
To find:
Saving = ?
Solution:
The original per price of the switch is given as = $ 0.69
Discounted price of 5 switches at $2.75
5 Switch price at original price = Original price * No of switches
= 0.69 * 5
= $ 3.45
Total saving at buying 5 switches = 3.45 - 2.75
=$0.7
So we will be saving a total of $0.7 at new rate
