The function f(x) which represents the total amount in the savings account in x months is given by: f(x)=25x+2000
Step-by-step explanation:
Given:
Enrico deposited $2000 in a savings account.
Each month he will deposit additional $25.
This shows that the rate at which the amount is increasing each month is constant.
Therefore, the model will be linear with a slope 25.
So , if x represents the number of months.
and f(x) represents the corresponding amount in the account.
Then the function f(x) is given by: f(x)=25x+2000
Which set of ordered pairs represents a function? {(0, 1), (1, 3), (1, 5), (2, 8)} {(0, 0), (1, 2), (2, 6), (2, 8)} {(0, 0), (0,
11111nata11111 [884]
Answer: {(0, 2), (1, 4), (2, 6), (3, 6)}
Step-by-step explanation:
For a relation to be considered a function, each x-value needs to have one corresponding y-value--it cannot have more than 1.
Since all the other sets of ordered pairs feature points with two x-values with different y-values, the set above is the only function of the provided options.
The answer is choice b.
check your answers by plugging numbers know for x.
y=x-4
if x is 4, y=4-4
y=0
y=x-4
If x is 5, y=5-4
y=1
which is valid based on the graph.
hope this helps.
The answer is going to be x=28
Here is how I did it:
You first need to subtract it first
6x/7+15-8=31
6x/7+7=31
you have to find the common denominator
6x/7+7=31
6x/7+7*7/7=31
Multiply all the terms by the same value to eliminate fraction denominators
7(6x+49)/7=7*31
6x+49=7*31
Multiply the numbers
6x+49=7*31
6x+49=217
Subtract 49 from both sides
6x+49=217
-49 -49
Now theres 6x=168
Divide both sides
6x=168

Simplify
x=28 is your answer
