Answer:
11 + c
Explanation:
In the parenthesis, 7 + c cannot be simplified, so there is no need for them. Now we have 7 + c + 4. Only 7 and 4 can be added. 7 + 4 = 11. The answer is 11 + c.
The magnitude can be found by using the PythaGORAS THEOREM:-
PQ = √[ (-3 - (-5))^2 + (4 - 2)^2 ]
Answer:
Cost of tools: $100
Cost for each chair: $25
Step-by-step explanation:
You can see that before 1 chair, the cost is at 100. This means that the cost of the tools is $100. Another way to determine this is to see that at 1 chair, the cost is $125. At 2, it's $150, and at 3 it's $175, etc. This tells you that the cost to produce each chair is $25, but it also tells you that the tools cost 100 dollars, since the total cost at 1 chair is $125, and each chair only costs $25.
Hope this helps!
The answer is A.
I only know how to explain by using the rule for reflection over x axis sorry.
The rule is (x,-y) x coordinate stays the same but you do the opposite for the y coordinate so -7.05 would be 7.05
