Rachel’s has a summer job working at the library. The graph below shows the relationship between the number of hours Rachael worked and the amount of money, in dollars, that Rachel earned?
Answer: m = 10 h
Step-by-step explanation: i did the test too
The Equation for Rachel Earning is m = 10h.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
From the graph we take two points (4, 35) and (5, 45).
So, the slope is
= (45 - 35) / (5-4)
= 10 /1
= 10
let Rachel work for h hours then Rachel earned
m = 10h

What is the domain of the relation?
Answer:
the domain of the relation is C
The domain of the given graph is -4≤x≤6. Therefore, the correct answer is option C.
From the given graph, extremes of line graph are (6, 4) and (-4, -4).
The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively.
Here, the domain of the graph is -4≤x≤6
The range of the graph is -4≤x≤4

On Dolores's tenth birthday her grandfather deposited $35 in a savings account for her. Each year, her grandfather deposited twice the amount of the previous year's deposit. How much money did her grandfather deposit on Dolores's eighteenth birthday?
Her grandfather deposits $28,680 on Dolores's eighteenth birthday.
What is a deposit?
A deposit is an amount of money that is placed into an account, typically a savings or checking account, with a financial institution such as a bank or credit union. The money deposited is held by the institution and can be withdrawn at a later time. Deposits can also refer to the act of putting money into an account.
In your example, on Dolores's tenth birthday her grandfather deposited $35 in a savings account for her. Each year, her grandfather deposited twice the amount of the previous year's deposit. On Dolores's eleventh birthday, the deposit was 352 = $70. The deposit for twelfth birthday was 702 = $140. Similarly, on Dolores's 18th birthday, the deposit was 35*2^8 = $28,680.
Hence, her grandfather deposits $28,680 on Dolores's eighteenth birthday.

A certain reality TV show lost 9,000 viewers over the past 3 months.If they lost the same number of viewers each month how many viewers did they lose each month
Answer:
3,000 viewers each month.
Step-by-step explanation:
1. they lost the same amount each month, which means you can divide the viewers lost by the number of months (3)
2. that would be 9,000/3
3. 3,000
4. You know you've got the right answer because this would multiply back to 9,000 with the same amount of viewers lost every month.

Classify each scale factor as a contraction or an expansion. Drag and drop the choices into the boxes to complete the table. Contraction Expansion 1.25 -2 3/4 1/5 3
Scale factor 1.25 is an expansion since we 'enlarge' the original size 1.25 times
Scale factor 3 is an expansion since we 'enlarge' the original size by 3 times
Scale factor -2 is also an expansion since we 'enlarge' the original size by 2 times but on the opposite direction of the centre of enlargement
Scale factor 3/4 is a contraction since we make the original size 'smaller' by 0.75 times
Scale factor 1/5 is also a contraction since we make the original size 'smaller' by 0.20 times
Literally, contraction means to reduce; while expansion means to increase.
The scale factors that represent contraction are 3/4 and 1/5The scale factors that represent expansion are 1.25, -2 and 3The following absolute value inequalities are used to determine if a scale factor (k) is an expansion or a contraction.
[tex]|k | > 1[/tex] represents expansion[tex]0 < |k | < 1[/tex] represents contractionSo, we have:
The absolute value of 1.25, -2 and 3 are greater than 1. i.e.
[tex]|1.25| > 1[/tex]
Remove absolute brackets
[tex]1.25 > 1[/tex]
[tex]|-2| > 1[/tex]
Remove absolute brackets
[tex]2 > 1[/tex]
[tex]|3| > 1[/tex]
Remove absolute brackets
[tex]3 > 1[/tex]
Hence, 1.25, -2 and 3 are all expansion scale ratios
The absolute value of 3/4 and 1/5 are between 0 and 1. i.e.
[tex]0 > |3/4| > 1[/tex]
[tex]0 > |0.75 | > 1[/tex]
Remove absolute brackets
[tex]0 > 0.75 > 1[/tex]
[tex]0 > |1/5| > 1[/tex]
[tex]0 > |0.2| > 1[/tex]
Remove absolute brackets
[tex]0 > 0.2 > 1[/tex]
Hence, 3/4 and 1/5 are all contraction scale ratios

Solve 8x - 5y = 18 for y.
y=(Use integers or fractions for any numbers in the expression.)
Answer:
y=8/5x + 18/5
Step-by-step explanation:
subtract 8x on both sides which ends up looking like:
-5y = 18 -8x
divide -5 on both sides which ends up like:
y= 8/5x - 18/5

In 3 years, Dianna will be 4 times as old as she was 33 years ago. How old is Dianna now?
Answer:
45 yrs old
Step-by-step explanation:
x + 3 = 4(x - 33)
:x + 3 = 4(x) - 132
Add 132 and minus x on both sides of equation
then: 135 = 3(x)
Answer:
Present age of Dianna is 45 years old
Step-by-step explanation:
Let "x" be the present age of Dianna
Given that, In 3 years, Dianna will be 4 times as old as she was 33 years ago
Then: In three years time Diana’s age would be x + 3
And: thirty three years ago it would have been x - 33
From given question,
x + 3 = 4 times as old as she was 33 years ago
x + 3 = 4(x - 33)
x + 3 = 4x - 132
x - 4x = -132 - 3
-3x = -135
x = 45
Thus present age of Dianna is 45 years old
