Answer:

$a_n=a_{n-1}+16$

Step-by-step explanation:

The given arithmetic sequence is

14,30,46,62

The first term of this sequence is

$a_1=14$

The common distance is obtained by subtracting a subsequent term from a previous term;

d=30-14

The common difference is

d=16

The recursive formula is given by:

$a_n=a_{n-1}+d$

We now plug in the known value for the common difference to get;

$a_n=a_{n-1}+16$

I need help understanding ratios and how they can be equivalent to each other

mart [117]

Ratios are the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

Equivalent ratios are like equivalent fractions, if they are the same value they are equivalent.

For example, to find two ratios that are equal to 1:7, first write 1:7 as the fraction 1/7.

Which of the following describes how to translate the graph y = |x| to obtain the graph of y = |x - 6|?. . . shift 6 units up. s

s2008m [1.1K]

Answer:

Shift 6 units right.

Step-by-step explanation:

Easiest way to answer this question is to plot the two graphs:

Let's plot these graphs and analyse each graph.

Lets take the graph of $y=|x|$ that is attached.

We can clearly see that graph intersects x axis at x=0 and then essentially looks like y=x is mirrored by the y axis.

Now when we look at the $y=|x-6|$ that is attached,

We can see that graph intersects x axis at x=6 and is a composite graph of $y=|x-6|$ and its mirrored graph by y=6.

We can clearly see that graph has moved 6 units to the right.

Can get some help on 2,4,22, 42 and 50 please

Fittoniya [83]

Answer:

2. zeros

4. difference

22. 79,158.5

42. 0.0099

50. 4.37

Step-by-step explanation:

2. Only adding 0s after a decimal point does not change the value.

4. Since you are subtracting then you estimate difference.

22. Add each number using place value.

75285

3971

0.5

__________

79258.5

42. 0.01 is really 0.0100. If you subtract 0.0001 then it is like subtracting 100-1 = 99 but in the decimal place. So it becomes 0.0099.

50. Subtract by lining up decimal places. Then move place values to subtract.
