Answer:
38 + 37i
Step-by-step explanation:
(9 − 4i)(2 + 5i)
FOIL
first: 9*2 = 18
Outer: 9*5i = 45i
inner: -4i * 2 = -8i
last : -4i * 5i = -20i^2 = -20(-1) = 20
Combine together
18+45i-8i +20
38 + 37i
Answer:
50 seconds
Solution: It is given that Clare is paid $90 for 5 hours of work. We know that $1 is equal to 100 cents. Hence, it take 50 seconds to earn 25 cents.
Answer: y = -2/5x + 3
Step-by-step explanation:
The formula for a line is: y = mx + b.
<em>m</em> is the slope of the line. We calculate this by looking at how many units the line travels vertically over how many units the line travels horizontally, or rise over run. In this example, we can see that the line goes down 2 units for every 5 it goes to the right, meaning the slope is equal to -2/5.
<em>b</em> is the y-intercept, or where the line crosses the y-axis. In this example, the line crosses the y-axis at (0, 3) making the <em>b</em> value equal to 3.
Therefore, the equation for this line put together is y = -2/5x + 3.
