You open a new bank account. The table shows the activity of your account for the first month. Positive numbers represent deposits and negative numbers represent withdrawals. What is your balance (in dollars) in the account at the end of the first month?
Answer:
$109.96
Step-by-step explanation:
Using the data from the table we need to add all of the transaction amounts together in order to calculate the final balance amount at the end of the first month since all of the transactions listed in the table are from the same month. (negative values cancel out the addition and instead subtract from the total)
100 + (-12.25) + 25.82 + 14.95 + (-18.56) = 109.96
Assuming that the initial account balance at the beginning of the month was $0 then the account balance at the end of the month would be $109.96
How do I find out what f(x) is if the graph defines h(x)
Answer:
f(x) = [tex]\frac{-h(x) + 7}{4}[/tex]
Step-by-step explanation:
h(x) is defined by the formula,
h(x) = -4f(x) + 7
If the graph attached is of the function 'h' and we have to find the function 'f',
h(x) - 7 = -4f(x)
4.f(x) = -h(x) + 7
f(x) = [tex]\frac{-h(x) + 7}{4}[/tex]
Therefore, function 'f' will be defined by,
f(x) = [tex]\frac{-h(x) + 7}{4}[/tex]

what was the scale factor? Show how you found your answer.
A(0,0) A’ (1.4)
B (4,0) B’ (9.4)
C (0.3) C’ (1.10)
PLEASE HELP
Answer:
2
Step-by-step explanation:
The scale factor is two since it's 2 times bigger than the actual figure.
Proof:
A to B = 4 units
A' to B' = 8 units
A to C = 3 units
A' to C' = 6 units
See how it keeps multiplying by 2.
4 x 2 = 8
3 x 2 = 6.

Answer:
j = 6
Step-by-step explanation:
1. What one needs to know
-Slope-intercept form
The formula of a line in slope-intercept form is;
y = mx + b
Where "m" is the slope. and "b" is the y-intercept.
2. Approach
The slope of the line is given. One has to solve for the y-intercept. Since a point on the line is given, one simply has to substitute in the point on the line and solve for b. The one substitutes in the other point with the unknown in it. One will then solve to find the unknown.
3. Finding "b"
It is given that this line has a slope of [tex]\frac{1}{5}[/tex], therefore, the equation of the line with the slope would look something like this;
y = [tex]\frac{1}{5}[/tex]x + b
It is given that (-4, -8) is on the line, substitute this point in;
-8 = [tex]\frac{1}{5}[/tex](-4) + b
Solve;
-8 = [tex]\frac{1}{5}[/tex](-4) + b
-8 = - 0.8 + b
-7.2 = b
The complete formula of this line is;
y = 0.2(x) - 7.2
( in decimals )
4. Solve of "j"
Point (j, -6) is on this line, substitute it into the formula
y = 0.2(x) - 7.2
-6 = 0.2(j) - 7.2
Inverse operations;
-6 = 0.2(j) - 7.2
+7.2 +7.2
1.2 = 0.2(j)
/0.2 /0.2
6 = j

The solution of the given equation.
Solution:
We have,
[tex]2(x+14)=40[/tex]
Using distributive property, we get
[tex]2(x)+2(14)=40[/tex]
[tex]2x+28=40[/tex]
Subtracting 28 from both sides.
[tex]2x=40-28[/tex]
[tex]2x=12[/tex]
On dividing both sides by 2, we get
[tex]x=6[/tex]
Therefore, the solution of the given equation is x = 6.

A concert had 6,000 audience members in attendance on the first night and the same on the second night. On the first night, the concert exceeded expected attendance by 20%, while the second night was below the expected attendance by 20%. What was the difference in percent of concert attendees and expected attendees for both nights combined?
Answer:
4%
Step-by-step explanation:
I added a screenshot of work, hopefully this helps you!
The difference in the percentage of concert attendees and expected attendees for both nights combined is 4%.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
Given that,
Number of audience attendants on the first and second night = 6,000
Let's say the excepted number of the audience on the first night was x then,
20% higher than x ⇒
1.2x = 6000
x = 5000
Error = 6000 - 5000 = 1000
Let's say the excepted number of the audience on the second night was x then,
20% lower than x ⇒
0.8x = 6000
x = 7500
Error = 7500 - 6000 = 1500
Combined expectation = 5000 + 7500 = 12500
Percentage = (1500 - 1000)/12500
Percentage = 0.04 → 4%
Hence "The difference in the percentage of concert attendees and expected attendees for both nights combined is 4%".

Step-by-step explanation:
Write an equation of the line in slope-intercept form.
f(3)=-2, f(0)=1
Answer:
The equation of the line in slope-intercept form is y = -x + 1
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-intercept ⇒ value y at x = 0The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the line∵ f(x) = y ⇒ is the function of the set of ordered pairs (x, y)
∴ f(3) = -2 is the point (3, -2)
∴ f(0) = 1 is the point (0, 1)
∴ x1 = 3 and y1 = -2
∴ x2 = 0 and y2 = 1
→ Substitute them in the rule of the slope to find it
∵ m = [tex]\frac{1--2}{0-3}[/tex] = [tex]\frac{1+2}{-3}[/tex] = [tex]\frac{3}{-3}[/tex]
∴ m = -1
→ Substitute it in the form of the equation above
∵ y = -1(x) + b
∴ y = -x + b
∵ b is the value of y at x = 0
∵ at x = 0, y = 1
∴ b = 1
∴ y = -x + 1
∴ The equation of the line in slope-intercept form is y = -x + 1
Nichole gets paid $13 and hour washing cars.
A) create an equation that models nicholes pay where x is the number of hours and y is the pay.
B) What is the slope? what is the intercept of the equation?
Answer:
A) y = 13x
B) Slope is 13, intercept is 0
Step-by-step explanation:
Answer:
y = 13x
The slope is 13
The y intercept is 0
Step-by-step explanation:
Since he gets $13 per hour, his pay can be represented by 13x, as x is the number of hours.
To create the equation, set this equal to y, as it represents his total pay.
So, the equation is y = 13x.
Using the equation y = mx + b, we can find the slope (m) and the y intercept (b)
Since this equation has 13 as the coefficient, the slope is 13. There is also no b value since nothing is being added to 13x, so the y intercept is 0.
which is not true about the solution to the equation? x+2.27=1.53

The first thing is that you have to break the √10. The only way you can break it is to make it into a 5 and a √2. So now it should look like this [tex]\frac{5}{5\sqrt{2}}[/tex]. Then we will divide the 5 by 5 and that'll become 1, so we are left with a [tex]\sqrt{2}[/tex] and that's it.
Find the solution to the systems of equations using the elimination method. 3x + 5y = 2 5x + 8y = 4
And then solve for y or x by using the elimination method
Answer:
[tex]\boxed{x = 4~~and~~y = -2}[/tex]
Step-by-step explanation:
3x + 5y = 2 (times 5) 15x + 25y = 10
5x + 8y = 4 (times 3) 15x + 24y = 12
.
15x + 25y = 10
15x + 24y = 12
y = -2
.
Substitute the value of y to one of equations
3x + 5y = 2
3x + 5(-2) = 2
3x - 10 = 2
3x = 2 + 10
3x = 12
[tex]x = \frac{12}{3}[/tex]
x = 4

Ariana has a dimes and y nickels. She has at most 12 coins worth a minimum of
$0.85 combined. Solve this system of inequalities graphically and determine one
possible solution.
PLEASE HELP
Answer:
Solution graph is attached in the answer area.
And one possible solution is (9, 2).
9 number of dimes and 2 number of nickels.
Step-by-step explanation:
Given that:
Number of dimes = [tex]a[/tex]
Number of nickels = [tex]y[/tex]
Total number of coins are at most 12 OR total number of coins are lesser than or equal to 12.
i.e. the inequality can be written as:
[tex]a+y \leq 12[/tex] ...... (1)
One dime is worth 10 cents or $0.10.
[tex]a[/tex] number of dimes are worth $0.10[tex]a[/tex].
One nickel is worth 5 cents or $0.05.
[tex]y[/tex] number of nickels are worth $0.05[tex]y[/tex].
Second inequality can be written as:
[tex]0.10a + 0.05 \ge 0.85[/tex]
OR
[tex]2a+y\ge17[/tex] ...... (2)
[tex]a \ge 0, y \ge 0[/tex] ...... (3)
When we graphically represent the inequalities, the graph attached in the answer area represents the answer.
One solution is (9, 2).
9 number of dimes and 2 number of nickels.
Joshua is making spaghetti and meatballs for dinner for his friends. Joshua makes 30 meatballs. If Joshua wants 5 meatballs on each plate of spaghetti, how many plates can Joshua make? Write an equation to represent the scenario, and solve.
Answer:
[tex]x = 6[/tex]
Step-by-step explanation:
Given
Let y represent the number of meatballs in total and x represents the number of plates.
[tex]y = 30[/tex]
[tex]Rate = 5[/tex] per plate
Required
Determine the value of x
To solve for x, we make use of the following expression.
[tex]y = Rate * x[/tex]
Substitute values for y and Rate
[tex]30 = 5 * x[/tex]
[tex]30 = 5 x[/tex]
Divide through by 5
[tex]30/5 = 5 x/5[/tex]
[tex]6 = x[/tex]
[tex]x = 6[/tex]
Hence, number of plates is 6
Alana has 2 1/4 bags of chocolate chips that she wants to use in 3 batches of chocolate chip cookies. How much of the chocolate chips will she use in each batch of cookies?
Answer:
1 1/3 bags of chocolate chips
Step-by-step explanation:
If Alana has 2 1/4 bags of chocolate chips that she wants to use in 3 batches of chocolate chip cookies, then we can say;
2 1/4 bags of cookies = 3 batches of chips
To determine how much of the chocolate chips will she use in each batch of cookies, we can say;
1 bag of cookies = x batches of chips
Equating both expressions
2 1/4 bags of cookies = 3 batches of chips
1 bag of cookies = x batches of chips
Cross multiply
2 1/4 x = 3
9/4 x = 3
9x/4 = 3
9x = 12
x = 12/9
x = 4/3
x = 1 1/3
Hence Alana will need 1 1/3 bags of chocolate chips
