Please help!! how do i figure out the percent of yearly budget column
Please give Brainiest.
Answer:
First, subtract the budgeted amount from the actual expense. If this expense was over budget, then the result will be positive. Next, divide that number by the original budgeted amount and then multiply the result by 100 to get the percentage over budget.
I hope that helps.

Tonisha has a lemonade stand. She has 31 dollars in expenses and wants to make at least 66 dollars per day. If x represents the amount of revenue from selling lemonade, an inequality to represent the amount of revenue she would need to generate would be:
Answer:
x-31(Greater than or equal to)66 -->x(greater than or equal to)97
Step-by-step explanation:
SHe wants to make a profit of 66, but with 31 bucks in expenses, this would need the revenue to be greater than 97 to cover the expenses and still make the profit

Answer:
1.) X = 1 2.) X = 7
Step-by-step explanation:
1.) 3x - 6 = 9
Subtract 6 on both sides
3x = 3
Divided 3 on both sides
X = 1
2.) -5x + 3x = 11 + 3
Put the like terms on both sides
-2x = 14
Divide both sides by 2
X = 7
5 and a half minus 7 equals
Answer:
-9/5; -1 4/5; -1.8
Step-by-step explanation:
2x + 3 = x -4 thats my question
Answer: -7
Step-by-step explanation:
Subtract xx from both sides.
2x+3-x=-42x+3−x=−4
2 Simplify 2x+3-x2x+3−x to x+3x+3.
x+3=-4x+3=−4
3 Subtract 33 from both sides.
x=-4-3x=−4−3
4 Simplify -4-3−4−3 to -7−7.
x=-7x=−7
Given 14 – 2(x + 8) = 5x – (3x – 34), prove x = -9 what are the steps to be able to prove x=-9
Answer: x = -9
steps
Simplifying
14 + -2(x + 8) = 5x + -1(3x + -34)
Reorder the terms:
14 + -2(8 + x) = 5x + -1(3x + -34)
14 + (8 * -2 + x * -2) = 5x + -1(3x + -34)
14 + (-16 + -2x) = 5x + -1(3x + -34)
Combine like terms: 14 + -16 = -2
-2 + -2x = 5x + -1(3x + -34)
Reorder the terms:
-2 + -2x = 5x + -1(-34 + 3x)
-2 + -2x = 5x + (-34 * -1 + 3x * -1)
-2 + -2x = 5x + (34 + -3x)
Reorder the terms:
-2 + -2x = 34 + 5x + -3x
Combine like terms: 5x + -3x = 2x
-2 + -2x = 34 + 2x
Solving
-2 + -2x = 34 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
-2 + -2x + -2x = 34 + 2x + -2x
Combine like terms: -2x + -2x = -4x
-2 + -4x = 34 + 2x + -2x
Combine like terms: 2x + -2x = 0
-2 + -4x = 34 + 0
-2 + -4x = 34
Add '2' to each side of the equation.
-2 + 2 + -4x = 34 + 2
Combine like terms: -2 + 2 = 0
0 + -4x = 34 + 2
-4x = 34 + 2
Combine like terms: 34 + 2 = 36
-4x = 36
Divide each side by '-4'.
x = -9
Can some one can do both
does the table represent y as a function of x? justify your answer
pleaseee helpp!!
Answer:
No it doesn't.
Step-by-step explanation:
In order for y to represent a function of x, no two x values can have the same y values. Basically x causes y and if y is the same under two different x values then the table isn't true. You can also use the vertical line test to ensure you are correct. I may not be correct but I believe I am

Solve x2 - 8x = 3 by completing the square. Which is the solution set of the equation?
A. (4 - √19, 4 + √19)
B. (4 - √11, 4 + √11)
C. (4 - √8, 4 + √8)
D. (4 - √3, 4 + √3)
Answer:
A.
Step-by-step explanation:
Step 1: Write equation
x² - 8x = 3
Step 2: Solve for x
Complete the Square: x² - 8x + 16 = 3 + 16Factor: (x - 4)² = 19Square root both sides: x - 4 = ±√19Add 4 to both sides: x = 4 ± √19Answer:
A
Step-by-step explanation:
because when doing these equations it is the same except one is positive and one is negative

Question 8
What is (4x - 5)(6x + 5) expressed as a trinomial?
Answer:
24x^2 -10x - 25
Step-by-step explanation:
24x^2 + 20x - 30x - 25
24^2 -10x - 25
Answer:
Simplifying
4x + -5 = 6x + 5
Reorder the terms:
-5 + 4x = 6x + 5
Reorder the terms:
-5 + 4x = 5 + 6x
Solving
-5 + 4x = 5 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
-5 + 4x + -6x = 5 + 6x + -6x
Combine like terms: 4x + -6x = -2x
-5 + -2x = 5 + 6x + -6x
Combine like terms: 6x + -6x = 0
-5 + -2x = 5 + 0
-5 + -2x = 5
Add '5' to each side of the equation.
-5 + 5 + -2x = 5 + 5
Combine like terms: -5 + 5 = 0
0 + -2x = 5 + 5
-2x = 5 + 5
Combine like terms: 5 + 5 = 10
-2x = 10
Divide each side by '-2'.
x = -5
Simplifying
x = -5

in as much detail as possible, explain how you would graph the equation.
9514 1404 393
Answer:
a) take it back to the author for clarification
b) use a graphing calculator
c) mark known points and draw the curve
Step-by-step explanation:
In the normal course of interpreting an algebraic expression, the evaluation of functions generally takes precedence over other operations. Here, that means this should be interpreted as ...
3·sin(1/2)·(x-1) +5
This is a (somewhat unusual) linear equation. It can be graphed by evaluating it for a couple of different x-values and drawing a line through the result. The first attachment shows a table of values and a graph of the line. (The slope of the line is an irrational value near 1.4382766 ≈ 105/73.)
__
It is common in Algebra studies to look at scaled and shifted versions of different functions. An alternative interpretation of the given expression would locate parentheses so that the sine function argument is clear:
[tex]y=3\sin{\left(\dfrac{1}{2}(x-1)\right)}+5[/tex]
This is the equation of a sine function vertically expanded by a factor of 3, vertically shifted by 5 units, horizontally expanded by a factor of 2, and horizontally shifted by 1 unit.
This can be graphed a couple of ways.
Relabel Axes
A way to do it is to draw a sine function (amplitude 1, period 2π, no vertical or horizontal shift), then relabel the axes so the function center-line is at y=5, the peak values are at +3 and -3 from that line, the period is 4π, and the whole graph is shifted right so the first upward center-line crossing is at x=1.
Choose Points
Perhaps an expected way to graph the function is to choose several values for x, find the corresponding y-values, and draw the curve through the points.
Recompute Points
Rather than relabel the axes or choosing random points, you could start with an (x, y) table of sine function values, then "adjust" those values as follows:
each x-value: multiply by 2 and add 1
each y-value: multiply by 3 and add 5
Plot the "adjusted" value pairs, and draw a curve through them. See the second attachment for a graph.

Comment on graphing
My preference for graphing anything that involves an electronically transmitted result or any detailed calculation is to use "technology". My current preference is a graphing calculator. Spreadsheet programs can also do a decent job of graphing, given enough points to work with.

"what value of x makes 5x+10=5(11-2x)
Answer:
5x + 10 = 5(11 - 2x)
5x + 10 = 55 - 10x
5x + 10x = 55 - 10
15x = 45
15x ÷ 15 = 45 ÷ 15
x = 3

Explain how to add linear expressions
Answer:
A linear expression is one that has a variable in it. Also, no variable is raised higher than a power of 1 or used as a denominator. So you can't divide by a variable. So if a linear equation is commonly expressed as "y= mx+b", a linear expression would be expressed as mx+b.

Multiply. 2√⋅5√⋅11−−√ Enter your answer, in radical form, in the box.
Answer:
√110
Step-by-step explanation:
The multiplication of the numbers √2, √5, and √11 is √110 after applying arithmetic operation.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
It is given that:
The number expression is:
= √2. √5 . √11
From the definition of the arithmetic operation, the operation in which we do the addition of numbers, subtraction, multiplication, and division.
= √(2x5x11)
= √110
Thus, the multiplication of the numbers √2, √5, and √11 is √110 after applying arithmetic operation.

What is the value of a in the equation 3 a plus b equals 54 when b equals 9?
Answer:-1/3b+18
Step-by-step explanation:
Let's solve for a.
3a+b=54
Step 1: Add -b to both sides.
3a+b+−b=54+−b
3a=−b+54
Step 2: Divide both sides by 3.
3a/3= -b+54
