Answer:
<h2>2b < 56 → b < 28</h2>
Step-by-step explanation:
< - less than
> - more than
≤ - less or equal than
≥ - more or equal than
-----------------------------------------
2b less than 56
<h3>2b < 56</h3>
solution:
2b < 56 <em>divide both sides by 2</em>
2b : 2 < 56 : 2
b < 28
Answer:
The values of x and y are x = 5 and y = -13 ⇒ B
Step-by-step explanation:
If the complex numbers are A = (a + bi) and B = (c + di), then
A + B = (a + c) + (b + d)i
- (b + d) is the imaginary part
Let us solve the question
∵ (x + yi) + (4 + 9i) = 9 - 4i
→ Add the real parts and the imaginary parts on the left side
∵ x, 4 are the real parts, and y and 9 are the imaginary parts
∴ (x + 4) + (y + 9)i = 9 - 4i
→ Compare the two sides, and equate the like terms
∵ 9 is the real part and -4 is the imaginary part
∴ x + 4 = 9
→ Subtract 4 from both sides
∴ x + 4 - 4 = 9 - 4
∴ x = 5
∵ y + 9 = -4
→ Subtract 9 from both sides
∵ y + 9 - 9 = - 4 - 9
∴ y = -13
The answer is 'c' because the scatterplot does increase exponentially from 1950 to 1960, and in 1960 the population looks about 8 times greater than 1950. It cant be II because even if the graph may seem as if it is going up, 1990 is decreasing. So that is why I think the answer is 'c'.
Hope this helps!
