Answer:
Last choice that shows points on +4 and -4 is the correct graph.
Step-by-step explanation:
We have been given equation 
. Now we need to find out which of the given number lines shows the corret solution set for .
We know that 
can be broken into two parts as:
and 
Same way we can break into two parts as:
and 
Hence last choice that shows points on +4 and -4 is the correct graph.
Answer:
a) 17, 29, 41, 53, 65....
b) 12n + 5
Let S be the amount in a savings account.
Let m be the number of months.
General equation
S = 132 + 27m
Specific question
July is the 7th month of the year including both January and July.
S = 132 + 7*27
S = 132 + 189
S = 321
Reasonableness?
Good question. You could estimate an answer.
Start with 150 dollars and say that you add 25 a month.
7 * 25 = 175
S = 150 + 175 = 325 All of this was done in my head. Since the exact answer obtained using the formula is 321, I think that's pretty reasonable using my estimate is a guide.
Answer:
b) 10 to 20
Step-by-step explanation:
You have to multiply each of the given numbers by 4, and add 8 to that result.
So:
And 60 is between the result of <u>10 and 20</u>, so that's the interval you have to select.
<em>The correct answer is b) 10 to 20</em>
