Answer:
Domain : { x| x≥3}
Step-by-step explanation:
The domain is the input values ( the x values)
X starts at 3 and goes to infinity
Domain : { x| x≥3}
Answer:
A. 10/11
Step-by-step explanation:
Algebraic Expression: 5x + 3y ÷ 2 = z
Word Phrase: 5 times x plus 3 times y divided by 2 equals z

I am 99.9% sure that this is correct, if not, I am truly sorry, and please forgive me. Thank You!
Answer: One solution
Step-by-step explanation:
y = 3x + 3
y = -2x + 3
-----------------------------------------------------------------------------------------------------------
To solve this, you need to understand a few things:
a) If two lines have the same slope but different y-intercepts, they are parallel when graphed and thus do not have any solutions
b) If two lines have the same slope and same y-intercepts, they are the same line when graphed and thus do not have infinitely many solutions
c) If two lines have different slopes (and/or y-intercepts), they have one solution
-----------------------------------------------------------------------------------------------------------
These two lines have different slopes but the same y-intercept (condition c)
So they have one solution
SOLUTION:
Case: Functions interval
Given: A function graph
Required: To find the region where the graph is increasing
Method:
The region where there is increase is where the graph has a positive slope, i.e. the region where the graph is moving from bottom left to top right.
We see the region on the graph as (-2, -2) to (2, 2)
Picking the x- axis only, this is (-2,2)
Final answer:
The final answer is (-2, 2)
