On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction. The number b varies directly with the number a. For example b = 2 when a = –2. Which equation represents this direct variation between a and b?
Answer:
a=-b? That might be wrong, sorry. But that's what it sounds like.
Step-by-step explanation:
The equation that represents the direct variation between the numbers a and b is b = -a.
Explanation:The equation that represents the direct variation between the numbers a and b is given by b = -a. In direct variation, when one variable increases, the other variable also increases, but in this case, they increase in opposite directions. For example, when a = -2, b = 2, and when a = 2, b = -2. Therefore, b varies directly with a, but in the opposite direction.

Ann has a net monthly income of $2,700.
Create a reasonable monthly budget for Ann. Be sure to include the following expenses:
Ann has a dog. Dog related expenses cost Ann about $150 every month.
Ann recently bought a new car. Her transportation expenses are $800 per month.
Answer:
ann would have $1700 left for bills or rent food etc
Step-by-step explanation:
Ann's proposed monthly budget takes into account her $2,700 net income and fixes expenses for her dog and new car. After allocating for these expenses, the budget proposes estimated allocations for rent, utilities, groceries, entertainment, and savings, with an emphasis on setting aside roughly 10% for savings as a good financial habit.
To create a reasonable monthly budget for Ann who has a net monthly income of $2,700, we need to allocate funds to her known expenses and then distribute the remaining amount to cover other typical living costs such as rent, utilities, groceries, and savings. Ann has two fixed expenses mentioned: dog-related expenses that cost about $150 every month, and her transportation expenses which are $800 for her new car. Once we subtract these amounts from her monthly income, we can allocate the rest to other necessary expenses.
Here is a proposed monthly budget for Ann:
Net Monthly Income: $2,700
Dog-Related Expenses: -$150
Transportation (Car Expenses): -$800
Rent: -$900 (estimate based on average rent costs)
Utilities: -$150 (estimate including electricity, water, and gas)
Groceries: -$300 (estimate for a single person)
Entertainment: -$100 (for dining out, movies, etc.)
Savings: -$200 (aiming for roughly 10% savings as good financial practice)
What values of c and d make the equation true? Assume x>0 and y >=0.
square root of 50x^6y^3/9x^8 = 5y^c square root of 2y/dx.
A.c = 1, d = 3
B.c = 1, d = 32
C.c = 2, d = 8
D.c = 2, d = 32
Answer:
A. c=1, d=3
Step-by-step explanation:
If x>0 and y>0, then
[tex]\sqrt{\dfrac{50x^6y^3}{9x^8}}=\sqrt{\dfrac{25\cdot 2y^2\cdot y}{9x^2}}=\dfrac{5y\sqrt{2y}}{3x}.[/tex]
If
[tex]\dfrac{5y\sqrt{2y}}{3x}[/tex]
is equal to
[tex]\dfrac{5y^c\sqrt{2y}}{dx},[/tex]
then
[tex]y=y^c\Rightarrow c=1,\\ \\3x=dx\Rightarrow d=3.[/tex]

What is the fifth term of the geometric sequence 5,15,45,...
Answer:
405
Step-by-step explanation:
This is a geometric sequence, so we need the common ratio and the first term
To find the common ratio, we take the second term and divide by the first term
15/5 =3
The common ratio is 3
We are multiplying by 3 each time
The first term is 5
The formula is
an = a1 * (r) ^ (n-1) where n is the term number
We want the 5th term
a5 = 5 * (3) ^ (5-1)
a5 = 5 *3^4
= 5 *81
= 405
The fifth term is 405.
[tex]a_{n}[/tex] = [tex]a_{1}[/tex]* [tex]r^{n-1}[/tex]
In this formula,[tex]a_{1}[/tex] is the first term,
r is the common ratio, and
n is the term number.
From the given sequence 5, 15, 45,..., we can identify the following:
[tex]a_{1}[/tex] = 5
r = 15 / 5 = 3 (common ratio)
Now, we need to find the fifth term (n = 5):
[tex]a_{5}[/tex] = 5 * [tex]3^{5-1}[/tex]
= 5 * [tex]3^{4}[/tex]
= 5 * 81
= 405
So, the fifth term of the geometric sequence is 405.
which values are solutions to the inequality below? check all that apply.
x^2 > 121
A) -12
B) 3
C) 13
D) 10
take square root of 121, which is 11
so -12, 3, 10,
The values that satisfy the inequality x² > 121 are -12 and 13, as their squares are greater than 121.
The question asks which values satisfy the inequality x² > 121. To find the solutions, we need to consider when x² is greater than the square of 11, since 121 is 11². There are two cases:
Case 1: x is greater than 11.
Case 2: x is less than -11.
Now, evaluating the provided options:
A) -12: (-12)² = 144 which is greater than 121. Hence, -12 is a solution.
B) 3: (3)² = 9 which is not greater than 121. Therefore, 3 is not a solution.
C) 13: (13)² = 169 which is greater than 121. Thus, 13 is a solution.
D) 10: (10)² = 100 which is not greater than 121. So, 10 is not a solution.
Therefore, the correct answers that satisfy the given inequality are -12 and 13.
John paid $222 for four hours of skiing and two hours boating. He paid $213 for two hours skiing and three hours boating. What is the cost pero hour of each activity?
Answer:
Skiing costs $30 per hour and Boating costs $51 per hour.
Step-by-step explanation:
Let cost per hour of skiing be x and cost per hour of boating be y. Let's dissect the problem into 2 simultaneous equations.
"John paid $222 for four hours of skiing and two hours boating":
[tex]4x+2y=222[/tex]
"He paid $213 for two hours skiing and three hours boating":
[tex]2x+3y=213[/tex]
Now, if we solve for x in the 2nd equation and plug it in the 1st equation, we will have the value for y. Work shown below.
[tex]2x+3y=213\\2x=213-3y\\x=\frac{213-3y}{2}\\Equation 1: 4x+2y=222\\Substituting :\\4(\frac{213-3y}{2})+2y=222\\2(213-3y)+2y=222\\426-6y+2y=222\\426-222=6y-2y\\204=4y\\y=\frac{204}{4}=51[/tex]
Hence, y = 51
Now, substituting this y value into the 1st equation and solving for x will give us the value of x.
[tex]First Equation: 4x+2y=222\\4x+2(51)=222\\4x+102=222\\4x=222-102\\4x=120\\x=\frac{120}{4}=30[/tex]
Hence, skiing costs $30 per hour and boating costs $51 per hour.

AABC has vertices at (-4,4), (0,0) and (-5,-2). find the coordinates of points A, B and C after a reflection across the y- axis.
Point A’: ____
Point B’: ____
Point C’: ____
The Y axis, would be when y = 0.
Point B is located on the Y -axis, so the coordinates would be the same.
For A and C the Y coordinate would remain the same and the X coordinate would be the opposite ( from negative to positive).
A (-4,4) would become (4,4)
B (0,0) would stay the same so would be (0,0)
C (-5,-2) would become (5,-2)
The coordinates after reflection across the y-axis are:
- Point [tex]\( A' \): \((4, 4)\)[/tex]
- Point [tex]\( B' \): \((0, 0)\)[/tex]
- Point [tex]\( C' \): \((5, -2)\)[/tex]
Step 1: Identify the original coordinates of the points.
- Point [tex]\( A \)[/tex] is at [tex]\((-4, 4)\).[/tex]
- Point [tex]\( B \)[/tex] is at [tex]\((0, 0)\).[/tex]
- Point [tex]\( C \)[/tex] is at [tex]\((-5, -2)\).[/tex]
Step 2: Apply the reflection across the y-axis.
- Reflecting a point across the y-axis changes the sign of the x-coordinate, while the y-coordinate remains unchanged.
Step 3: Calculate the new coordinates.
For Point [tex]\( A \):[/tex]
- Original coordinates: [tex]\((-4, 4)\)[/tex]
- Reflected coordinates: [tex]\((4, 4)\)[/tex]
- Negate the x-coordinate: [tex]\(-(-4) = 4\)[/tex]
- Keep the y-coordinate the same: [tex]\(4\)[/tex]
For Point [tex]\( B \):[/tex]
- Original coordinates: [tex]\((0, 0)\)[/tex]
- Reflected coordinates: [tex]\((0, 0)\)[/tex]
- Negate the x-coordinate: [tex]\(-0 = 0\)[/tex]
- Keep the y-coordinate the same: [tex]\(0\)[/tex]
For Point [tex]\( C \):[/tex]
- Original coordinates: [tex]\((-5, -2)\)[/tex]
- Reflected coordinates: [tex]\((5, -2)\)[/tex]
- Negate the x-coordinate: [tex]\(-(-5) = 5\)[/tex]
- Keep the y-coordinate the same: [tex]\(-2\)[/tex]
Step 4: Write the coordinates of the reflected points.
- Point [tex]\( A' \): \((4, 4)\)[/tex]
- Point [tex]\( B' \): \((0, 0)\)[/tex]
- Point [tex]\( C' \): \((5, -2)\)[/tex]
So, the coordinates after reflection across the y-axis are:
- Point [tex]\( A' \): \((4, 4)\)[/tex]
- Point [tex]\( B' \): \((0, 0)\)[/tex]
- Point [tex]\( C' \): \((5, -2)\)[/tex]
59 =7r+3 what is the answer
Answer:
r=8
Step-by-step explanation:
59 =7r+3
Subtract 3 from each side
59 -3 = 7r+3-3
56 = 7r
Divide each side by 7
56/7 = 7r/7
8 =r
Answer:
[tex]\boxed{\bold{r=8}}[/tex]
Step-by-step explanation:
Switch sides
[tex]\bold{7r+3=59}[/tex]
Subtract 3 from both sides
[tex]\bold{7r+3-3=59-3}[/tex]
Simplify
[tex]\bold{7r=56}[/tex]
Divide both sides by 7
[tex]\bold{\frac{7r}{7}=\frac{56}{7}}[/tex]
Simplify
[tex]\bold{r=8}[/tex]
Which of these is equal to the value of 9-(-5)
The expression 9-(-5) simplifies to 9 + 5, which equals 14 when the numbers are added together.
To solve the expression 9-(-5), you should remember that subtracting a negative number is the same as adding its positive counterpart. Therefore, we change the subtraction of a negative number to the addition of a positive number. Following these steps, we have:
9 - (-5) = 9 + 5
Now, we simply add the numbers together:
9 + 5 = 14
So, the expression 9-(-5) equals 14.

Write the equation of the line that passes through (–1, 5) and has a slope of 3 in point-slope form.
Answer:
y - 5 = 3 (x + 1)
Step-by-step explanation:
Start with the pertinent equation of a straight line: the point-slope form:
y-k = m(x-h), where (h,k) is the given point and m is the given slope.
Then y - 5 = 3(x-(-1) ), or y - 5 = 3 (x + 1).
Answer: [tex]y-5=3(x+1)[/tex]
Step-by-step explanation:
By definition the equation of the line written in point-slope form is the following:
[tex]y-y_1=m(x-x_1)[/tex]
Where ([tex]x_1,y_1[/tex]) is a point of the line and m is the slope.
You know that the slope is 3 and the ine that passes through (-1, 5).
Then, when you substitute these values into the equation, you obtain:
[tex]y-5=3(x-(-1))[/tex]
[tex]y-5=3(x+1)[/tex]

A local dairy farmer collects 490 gallons of milk from his cows. He keeps 1/35 of the milk for his own use, and sells the rest. Each quart of milk sells for 35 cents. In dollars, how much does he earn from selling his milk each day?
Answer:
666.4 dollars per day
Step-by-step explanation:
Total milk farmer has is 490 gallons
He keeps 1/35 of 490 gallons
so he keeps = 1/35*490= 14 gallons
He sells remaining milk.
Remaining milk = 490-14 = 476 gallons
1 gallon = 4 quart (conversion formula)
so 476 gallon = 4 * 476 = 1904 quart
selling price of 1 quart = 35 cents = 0.35 dollars
so selling price of 1904 quart = 0.35*1904 = 666.4 dollars
So he makes 666.4 dollars per day.

Answer:
[tex]\textsf{A)}\;\;\; -2, \; \left|-\dfrac{4}{5}\right|, \; |-1|, \;|3.5|, \;|-4.2|[/tex]
[tex]\newline[/tex]
Step-by-step explanation:
[tex]\newline[/tex]
Given numbers:
[tex]\newline[/tex]
[tex]|-4.2|, \;\left|-\dfrac{4}{5}\right|, \; |-1|, \;-2, \; |3.5|[/tex]
[tex]\newline[/tex]
The absolute value of a number represents the distance of a number from zero on the number line, regardless of direction. This means that the absolute value of a number is always non-negative. For example, |-4.2| = 4.2, because the distance from -4.2 to 0 is 4.2 units.
[tex]\newline[/tex]
Evaluate each term:
[tex]\newline[/tex]
[tex]|-4.2|=4.2[/tex]
[tex]\left|-\dfrac{4}{5}\right|=\dfrac{4}{5}=0.8[/tex]
[tex]|-1|=1[/tex]

[tex]|3.5|=3.5[/tex]
[tex]\newline[/tex]
Now, arrange them from least to greatest:
[tex]\newline[/tex]

An architect is using software to design the interior of a rectangular room. On the floor plan, the coordinates of two consecutive corners of the room are (3, 15) and (18, 2). The architect wants to place a window in the center of the wall containing these two points. What will be the coordinates of the center of the window on the floor plan?
A.) (17, 21)
B.) (10.5, 8.5)
C.) (21, 17)
D.) (8.5, 10.5)
Answer:
The answer is B.
Step-by-step explanation:
The architect wants to place a window in the center of the wall containing these two points: (3, 15) and (18, 2).
The coordinates of the center of the window are those of the mid-point betwween the two points: ( (3+18)/2, (15+2)/2 ) = (10.5, 8.5)
The answer is B.
Answer:
Step-by-step explanation:
ignore the text n focus on the coordinates (3, 15) and (18, 2) and that "the architect wants to place a window in the center of the wall containing these two points."
so the window will be right in the middle of (3, 15) and (18, 2).
take the average of the coordinates: (3+18)/2=10.5 n (15+2)/2=8.5
ans is B. (10.5,8.5)

The vertices of a triangle are A(7,5) B(4,2) and C(9,2) what is mABC
Answer:
A(7,5)
Step-by-step explanation:
This is correct because the area of a triangle is b × h = a.
Answer:
The measure of ∠ABC is 45°.
Step-by-step explanation:
Given : The vertices of a triangle are A(7,5) B(4,2) and C(9,2).
To find : What is ∠ABC ?
Solution :
First we side the length of the sides,
Using Distance formula,
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
Length of side AB, A(7,5) and B(4,2)
[tex]c= \sqrt{(7-4)^2 + (5-2)^2} \\c= \sqrt{(3)^2 + (3)^2} \\c= \sqrt{9+9} \\c= \sqrt{18}[/tex]
Length of side BC, B(4,2) and C(9,2)
[tex]a= \sqrt{(4-9)^2 +(2-2)^2} \\a= \sqrt{(-5)^2 + 0} \\a= \sqrt{25} \\a= 5[/tex]
Length of the side AC, A(7,5) and C(9,2)
[tex]b = \sqrt{(7-9)^2 +(5-2)^2}\\ b= \sqrt{(-2)^2 + (3)^2} \\b= \sqrt{4+ 9}\\b=\sqrt{13}[/tex]
By the Law of Cosines,
[tex]\cos B=\frac{a^2 + c^2 -b^2}{2ac}[/tex]
Substitute the values,
[tex]\cos B=\frac{(5)^2 + (\sqrt{18})^2 - (\sqrt{13})^2}{2\times 5\times \sqrt{18}}[/tex]
[tex]\cos B =\frac{25+18-13}{10\sqrt{18}}[/tex]
[tex]\cos B=\frac{30}{10\sqrt{18}}[/tex]
[tex]\cos B =\frac{3}{\sqrt{18}}[/tex]
[tex]\cos B= \frac{3}{3\sqrt{2}}[/tex]
[tex]\cos B= \frac{1}{\sqrt{2}}[/tex]
Taking Inverse Cosine function,
[tex]B= \cos^{-1}( \frac{1}{\sqrt{2}})[/tex]
[tex]B=45^\circ[/tex]
Therefore, The measure of ∠ABC is 45°.
