We can simply add the expression to simplify the expression. So,
(7+3i)+(-8+9i) =7 +3i -8+9i Get rid of paranthesis.
=(7-8)+(3i+9i) Group the like terms.
= -1 + 12i
Answer:
3
Step-by-step explanation:
Divide

To graph the equation, plot a few points then connect then with a line.
f(x) = 440 - 55x
Plug in numbers for x to get the y value.
f(0) = 440
f(1) = 385
f(2) = 330
f(3) = 275
f(4) = 220
f(5) = 165
So when you graph these points, the y intercept is y = 440 because the graph crosses the y axis at (0, 440).
The x intercept is where the graph crosses the x axis. This happens when y = 0.
0 = 440 - 55x. Solve for x.
55x = 440
x = 8
So the x intercept is x = 8
Answer:
Yes, the given question is a statistical question.
Step-by-step explanation:
Given: statement is "What is the typical height of dog kennels at Keita's Kennels?"
To check: whether the given statement is a statistical question
Solution:
A statistical question is one for which you will generally get more than one answer.
For example "What's the age of the students in your school?" is a statistical question but "What's your age?" is not a statistical question.
The given statement "What is the typical height of dog kennels at Keita's Kennels?" has a single answer only, so the given question is statistical
