Use the graph to evaluate f (-2)
Answer:
f(- 2) = 4
Step-by-step explanation:
To evaluate f(- 2), locate x = - 2 on the x-axis, go vertically up to meet the graph at (- 2, 4 )
The value of y at x = - 2 is 4, then
f(- 2) = 4

Is the following benefit true for credit cards, debit cards, both or neither?
They have no interest rate.
Answer:
too what i know no they don't answer=(false)
Step-by-step explanation:
hope this helps if it is wrong then you know it was true..
Note that the benefit of having no interest rate is true for debit cards, but NOT for credit cards.
How is this so?The benefit of having no interest rate applies to debit cards.
Debit cards allow you to spend funds directly from your bank account, and typically, no interest is charged on the transactions made using a debit card since you are using your own money.
On the other hand, credit cards can have an interest rate applied to the outstanding balance if not paid in full by the due date.
When you use a credit card, you are essentially borrowing money from the credit card issuer, and if you carry a balance, interest may be charged on the amount owed.
Thus , the benefit of having no interest rate is true for debit cards, but false for credit cards.

Write an equation in the form of y=Mx+b to model the given representation
Answer:
y= 5x+5
Step-by-step explanation:
you do the rise over run for the slop which is m
the slope is 5 down and 5 to the right
it is also positive
the y-intercept is 5 cuz on the y line the point dot is 5 which is also b
so if it's 5 over 5 (rise over run) then it will become one whole which is just 5
you now put everything together
y=5x+5
What is the intermediate step in the form (x + a)2 = b as a result of completing the
square for the following equation?
x2 + 34 = 10x
Answer:
So the intermediate step in question is (x - 10)² = 66
Step-by-step explanation:
Let's find out:
x² + 34 = 10x
x² - 10x = -34
x² - 20x + 100 = 66
(x - 10)² = 66
x - 10 = ± √66
x = 10 ± √66
x ≈ 18.12, 1.88

Hayley borrowed $1,854 from her parents. She agreed to repay them in equal installments throughout the next 18 months. How much will Hayley still owe her parents after a year
Answer: $ 618
Step-by-step explanation:
Money borrowed = $1,854
Total months taken to repay = 18 (Number of installments)
Money paid per month = [tex]\dfrac{\text{Money borrowed}}{\text{Number of installments}}[/tex]
[tex]=\dfrac{1854}{18}=\$103[/tex]
Now , money paid in 1 year = 12 x $ 103 =$ 1236 [1 year = 12 months ]
After a year , Haley still owe = $1,854 - $ 1236= $ 618
Hence, Haley still owe her parents $618 after a year .

Answer: Choice C
x intercept is (4,0)
y intercept is (0,2)
=======================================================
Work Shown:
To find the x intercept, we plug in y = 0 and solve for x
2x+4y = 8
2x+4(0) = 8
2x+0 = 8
2x = 8
x = 8/2
x = 4
We have x = 4 pair up with y = 0. So we have (x,y) = (4,0) as the x intercept.
This is the location where the graph crosses the x axis.
--------------
The y intercept is a similar story, but we use x = 0 to find y.
2x+4y = 8
2(0)+4y = 8
0+4y = 8
4y = 8
y = 8/4
y = 2
The value x = 0 leads to y = 2. This gets us (x,y) = (0,2) as the y intercept.
This is the location where the graph crosses the y axis.
A new car is purchased for $32,500. The car depreciates every year ata
rate of 14%. Write an exponential function that represents that situation
Answer:
[tex]y=32500(0.86)^{x}[/tex]
Step-by-step explanation:
General exponentially depreciating function is given as
[tex]y= a(1-b)^{x}[/tex]------------(1)
Where a is initial value, b is percent depreciation/unit time and x is time
Here
[tex]a=32,500 \ \ \ b=0.14 \ \ \ and \ \ x \ is \ time \ in \ years[/tex]
Substituting above values in equation (1)
[tex]y=32500(0.86)^{x}[/tex]
At x=0
[tex]y=32500(0.86)^{0}\\y=32500[/tex]
At x=1
[tex]y=32500(0.86)^{1} \\y=27950[/tex]

A bag contains twelve balls labeled 1 through 12. One ball will be randomly picked. What is the probability of picking a multiple of 3?
Hey Love! The person above me is wrong out the wa-zoo! But here is the answer straight from ALEKS
Answer:
1/2
Step-by-step explanation:
There are six balls with even numbers. These are 2, 4, 6, 8, 10, and 12.
There are twelve balls, so there are twelve possible outcomes.
We are picking randomly, so each outcome is equally likely.
So the probability of picking an even number is 6/12.
The fraction can be simplified to 1/2.
Credits to ALEKS I got this answer from them so I know it's correct!
