The unit rate of fragance a is $ , and the unit rate of fragrance b is $
Answer:
Table
Bottles Price($)
3 78
6 156
9 234
From that you can find the unit price: 78 / 3 = 156 / 6 = 234 / 9 = 26.
That means that the unit rate of this fragance is $26.
If you call x the number of bottles the equation is
Price = unit rate * number of bottles = 26x.
Now compare this information with that on your graph to compare the unit rates.
This can help you fo find the unit rate in from your grpah: the unit rate is the slope of the line =
[change in y-coordinate] / [change in the x-coordinate]

Answer:
3 and 78
Step-by-step explanation:
On a coordinate plane, a line goes through points (0, 1) and (3, 0). Y = one-half x minus 1. Identify the slope of the graphed line: Identify the y-intercept of the graphed line: Identify the slope of the line given by the equation: Identify the y-intercept of the line given
Answer:
(a)
\(Slope=-\dfrac{1}{3}\\$y-intercept =1\)
(b)
\(Slope = \dfrac12\\$y-intercept=$ -1\)
Step-by-step explanation:
Given a line which goes through the points: (0, 1) and (3, 0).
(a)Slope
\(m=\dfrac{0-1}{3-0}\\m=-\dfrac{1}{3}\)
The slope-intercept form of the equation of a line is given as: y=mx+b
Therefore:
\(y=-\dfrac{1}{3}x+b\\$From the point (0,1), When x=0, y=1; Therefore:$\\1=-\dfrac{1}{3}(0)+b\\$Therefore:\\b=1\)
The y-intercept of the line through points (0, 1) and (3, 0) is 1.
(b)Given the line:
\(y=\dfrac12x-1\)
Comparing with the slope-intercept form of the equation of a line: y=mx+b
\(Slope = \dfrac12\\$y-intercept=$ -1\)
Answer:
Identify the slope of the graphed line:
✔ -1/3
Identify the y-intercept of the graphed line:

Determine that the value x=9 of the following expiration given x2+3x-5
Step-by-step explanation:
To determine the value of x that satisfies the expression x^2 + 3x - 5 when x = 9, we simply substitute 9 for x and evaluate the expression:
9^2 + 3(9) - 5 = 81 + 27 - 5 = 103
Therefore, when x = 9, the expression x^2 + 3x - 5 evaluates to 103.

Answer:
y = -5/2x + 7
Step-by-step explanation:
The line is perpendicular, so mx is the reciprocal of 2/5 which would be -5/2. Then you plug that and (4, -3) into the equation y = mx + b, which will come out as -3 = (-5/2)(4) + b. Multiply mx to get -3 = -10 + b. Add 10 to both sides to get 7 = b. Plug in mx and b into the equation and you have your answer.
At a dairy plant, a milk tank can be filled in 6 hours (using the in-valve). Using the out-valve, the tank can be emptied in 10 hours. If both valves are open and milk is being pumped into the tank, how long will it take to fill the tank?
In one hour, 1/6 of the tank will be filled and 1/10 of the tank will be emptied. As a net result,
\(\begin{aligned}\dfrac{1}{6} - \dfrac{1}{10} &= \dfrac{1}{6}\cdot\bold{\dfrac{5}{5}} - \dfrac{1}{10}\cdot\bold{\dfrac{3}{3}}\\[0.5em]&= \dfrac{5}{30} - \dfrac{3}{30}\\[0.5em]& = \dfrac{2}{30}\\[0.5em]& = \dfrac{1}{15}\end{aligned}\)
we see that 1/15 of the tank is filled per hour when both valves are open.
It will take 15 hours to fill the tank.

Owen runs a pet store that sells rabbits. He wants to ensure he has more than 1 pound of dry food for every four rabbits he has in the store, and he currently has 5.7 pounds of dry food. Write and solve an inequality for the scenario. How many rabbits can Owen have in the store?
Owen can have a minimum of 22 rabbits in the store.
Owen can have a maximum of 22 rabbits in the store.
Owen can have a maximum of 23 rabbits in the store.
Owen can have a minimum of 23 rabbits in the store.
By finding an inequality, we see that:
"Owen can have a maximum of 22 rabbits in the store."
How many rabbits can Owen have in the store?
We know that he needs 1lb of food for every 4 rabbits, and we know that he currently has 5.7 lb of food.
Then the maximum number of rabbits that he can feed with that food is:
max = (5.7)*4 = 22.8
So the number of rabbits that he can have is:
x < 22.8
or
x ≤ 22
To just have whole numbers.
Then the correct option is:
"Owen can have a maximum of 22 rabbits in the store."

The value of P for the given angles of the quadrilaterals is 6.
What is geometry?One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.
Given that the two opposite angles are 4P + 12 and 36 respectively.
The value of P for the two opposite angles will be calculated as:-
4P + 12 = 36
4P = 36 - 12
4P = 24
P = 24 / 4
P = 6
Hence, the value of P for the given angles of the quadrilaterals is 6.

The altitude is given as follows:
6.
Hence the length x is given as follows:

2x = 36
x = 18.
Applying the Pythagorean Theorem, the length y is given as follows:

A rock group needs to choose 3 songs to play at the annual Battle of the Bands. How many ways can they choose their set if they have 15 songs to pick from?
We need to find the number of combinations of 3 songs out of 15 songs.
The combination of r items out of a total of n items is given by the formula:
\(C(n,r)=\frac{n!}{r!(n-r)!}\)where
\(n!=n(n-1)(n-2)...(2)(1)\)In this problem, we have:
\(\begin{gathered} n=15 \\ r=3 \end{gathered}\)Thus, we obtain:
\(\begin{gathered} C(15,3)=\frac{15!}{3!(15-3)!} \\ \\ C(15,3)=\frac{15\cdot14\cdot13(12!)}{3\cdot2\cdot1(12!)} \\ \\ C(15,3)=\frac{15}{3}\cdot\frac{14}{2}\cdot13 \\ \\ C(15,3)=5\cdot7\cdot13 \\ \\ C(15,3)=455 \end{gathered}\)Answer: The number of ways they can choose their set of songs is 455.
Please tell me which one are positive and negative
Answer:
Negative, Positive, Negative, Positive
Step-by-step explanation:
1. 18.75 + (-19)
Adding a negative is the same as subtracting. 18.75 - 19 is -0.25 so the first answer is negative.
2. \(-3 \frac{7}{10}\) + \(3\frac{4}{5}\)
If you convert the fraction in the second term to one with the same denominator (three and 8 10ths), you can see that since 8 tenths is more than 7 tenths, the equation will result in positive 1/10
3. 9.4 + (-\(9\frac{3}{5}\))
3/5 is the same as 6/10 or .60
9.6 is more than 9.4, so the negative is further from zero than the positive.
4. -7 + 7 + 1/2
-7 + 7 is zero. zero + 1/2 is positive 1/2

B. x² + 3x-3 <0
C. x²-3x+3<0
D. x² + 3x-3>0
The inequality expression that corresponds to the solution of the inequality graph is x² + 3x - 3 < 0.
option B.
What is the solution of the inequality?The inequality expression that corresponds to the solution of the inequality graph is determined by simplifying the equations as follows;
The solution of the graph,
x > -4 and x < 1
The first equation with "≥" is ruled out because the graph doesn't have a thick dot.
Let's simplify the second expression;
x² + 3x - 3 < 0
solve using quadratic formula;
x > -3.79 or x < 0.79
The third expression is ruled out since its solution will be complex.
For the last expression;
x² + 3x - 3 > 0
x < -3.79 or x > 0.79
Thus, the correct inequality expression is x² + 3x - 3 < 0.

Solve for m. -2m-4m-17=1 m=
m = -\(\frac{17}{7}\)
Step-by-step explanation:Here are the steps to figuring out your problem:1. Combine like terms
-2m - 4m - 17 = 1m
-6m - 17 = 1m
2. Multiply by 1
-6m - 17 = 1m
-6m - 17 = m
3. Add 17 to both sides
-6m - 17 = m
-6m - 17 + 17 = m + 17
4. Simplify
Add the numbers:
-6m - 17 + 17 = m + 17
-6m = m + 17
5. Subtract m from both sides
-6m = m + 17
-6m - m = m + 17 - m
6. Simplify
Combine like terms:
-6m - m = m + 17 - m
-7m = m + 17 - m
Combine like terms:
-7m = m + 17 - m
-7m = 17
7. Divide both sides by the same factor
-7m = 17
\(\frac{-7m}{-7}\) = \(\frac{17}{-7}\)
8. Simplify
Cancel terms that are in both the numerator and denominator:
\(\frac{-7m}{-7}\) = \(\frac{17}{-7}\)
m = \(\frac{17}{-7}\)
Divide the numbers:
m = -\(\frac{17}{7}\)
Solution:m = -\(\frac{17}{7}\)
