Answer:
x - 2y = -15
Step-by-step explanation:
Given: m = 1/2 and (-3, 6)
We are given slope and a point.
The equation of the line y - y1 = m (x - x1)
y - 6 = 1/2 (x - (-3))
y - 6 = 1/2 (x + 3)
y - 6 = 1/2x + 3/2
1/2x - y = -6 - 3/2
1/2x - y = -15/2
Taking LCD as 2, we get
x - 2y = -15

Bhavik bought 33 liters of milk and 55 loaves of bread for a total of \$11$11. A month later, he bought 44 liters of milk and 44 loaves of bread at the same prices, for a total of \$10$10. How much does a liter of milk cost, and how much does a loaf of bread cost?
Answer: The cost of 1 liter milk is $ 0.75 and the cost of a loaf of bread is $1.75
Step-by-step explanation:
Let the cost of one liter of milk is m dollar and the cost of one loaf of bread is b dollar.
Since, the total cost of the 3 liter milk and 5 loaf of bread = $ 11
That is, 3 m + 5 b = 11 ----------(1)
And, the cost of the 4 liter of milk and 4 loaf of bread = $ 10
That is, 4 m + 4 b = 10 -----------(2)
4 × Equation (1),
12 m + 20 b = 44 -----------(3)
3 × Equation (2),
12 m + 12 b = 30 --------------(4)
Equation (3) - Equation (4),
We get, 8 b = 14
⇒ b = 14/8 = 1.75
By putting the value of b in equation (1)
We get,
3 m = 11 - 1.75×5 ⇒ m = 2.25/3 = 0.75
Thus, the price of one liter of milk = $ 0.75
And, the price of one loaf = $ 1.75
Answer:
The cost of 1 liter milk is $ 0.75 and the cost of a loaf of bread is $1.75

In a previous question we have found 2 things.
1. That we are working with a right angle triangle2. That two of the sides are both 9. We did not require the third side. Now we do.If two of the sides are 9 then in this case only we can use the Pythagorean theorem to find the third side. That is because the the base and height meet at right angles.
a^2 + b^2 = c^2
9^2 + 9^2 = c^2
81 + 81 = c^2
c^2 = 162
sqrt(c^2) =sqrt(162)
c = 12.71
Perimeter
The perimeter = 9 + 9 + 12.71 = 30.7

Lamar wants to determine the movie preferences
Answer:
male comedy: 31 male drama: 9
female comedy: 36 female drama: 24
Step-by-step explanation:
add f+m=100 total
31 males for comedy
40 males - 31 males = 9 males for drama
55% chose comedy so 55-31 males = 24 females for comedy
60 total females - 24 for comedy = 36 females for drama
Answer:
Dramas Comedies
Males 9 31
Females 36 24
Step-by-step explanation:
It is given that Lamar surveyed 40 males and 60 females about whether they prefer dramas or comedies.
Total males = 40
Total females = 60
Total people surveyed = 40 + 60 = 100
It is given that 55% of surveyed people preferred comedies.
People preferred comedies = [tex]100\times \frac{55}{100}=55[/tex]
It is given that males who preferred comedies = 31
Males who preferred drama is the difference of number of males and males who preferred comedies.
Males, drama = 40 - 31 = 9
Females who preferred comedies is the difference of people who preferred comedies and males who preferred comedies.
Females, comedies = 55 - 31 = 24
Females who preferred drama is the difference of number of females and females who preferred comedies.
Females, drama = 60 - 24 = 36
Therefore the table can be filled as
Dramas Comedies
Males 9 31
Females 36 24
In a supermarket bin the number of packages of red to peppers to the number of packages of green peppers is in the ratio of 8 is to 13.The peppers are sold in 2 pound packages.What is the least possible weight of red peppers in the bin?
Answer:
16 pounds
Step-by-step explanation:
The ratio of no. of packages of red pepper to no. of packages of green pepper is given 8 is to 13.
So, atleast 8 packages of red pepper are sold
Therefore, least possible weight of red peppers in the bin = 2×8 = 16 pounds.
The least possible weight of red peppers in a supermarket bin with a ratio of 8 to 13 of red to green peppers, where each package weighs 2 pounds, is 16 pounds.
To find the least possible weight, we assume the smallest number of packages that maintain the ratio. Multiplying both numbers of the ratio by 2 pounds gives us the weight of the red and green peppers, but since we want the least possible weight of red peppers, we'll only calculate for red.
Therefore, if we have 8 packages of red peppers, each weighing 2 pounds, the calculation would be:
8 packages × 2 pounds/package = 16 pounds of red peppersSuki rode her bike 4/5 mile. Claire rode her bike 1/3 mile. they want to compare how far they each rode their bikes using the Benchmark 1/2
Suki rode her bike a longer distance than Claire because when comparing each of their distances to the benchmark of 1/2 mile, Suki's distance (4/5 mile) is greater than the benchmark (1/2 mile), while Claire's distance (1/3 mile) is less than the benchmark. Therefore, Suki rode a longer distance than Claire in relation to the benchmark.
Suki's Distance with Benchmark (1/2):
Suki rode her bike for 4/5 miles.
The benchmark is 1/2 mile.
Comparison: [tex]\frac{4}{5} > \frac{1}{2}[/tex]
Interpretation: Suki's distance ( 4/5 miles) is greater than the benchmark 1/2 mile.
Claire's Distance with Benchmark (1/2):
Claire rode her bike for 1/3 mile.
The benchmark is 1/2 mile.
Comparison: [tex]\frac{1}{3} < \frac{1}{2}[/tex]
Interpretation: Claire's distance ( 1/3 mile) is less than the benchmark 1/2 mile.
Overall Comparison:
Suki's distance (4/5) is greater than Claire's distance (1/3).
Interpretation: Suki rode her bike a longer distance than Claire.
In summary, both Suki and Claire are comparing their distances to the benchmark of 1/2 mile. Suki's distance is greater than the benchmark, while Claire's distance is less than the benchmark. Therefore, Suki rode a longer distance than Claire.

a/5x−10 + a/6x−12
To simplify the expression, find the common denominator, distribute the 'a' to each term, and combine like terms.
Explanation:To simplify the expression a/5x-10 + a/6x-12, we need to find a common denominator for the two terms. The common denominator is 30x(x-2). We then multiply each term by the appropriate factor to get a common denominator. This simplifies the expression to:
a(6x-12) + a(5x-10) / 30x(x-2)
Now, we can distribute the 'a' to each term:
6ax - 12a + 5ax - 10a / 30x(x-2)
Combining like terms, we get a(11x - 22) / 30x(x-2).

Two parallel lines are crossed by a transversal . What is the value of k?
Answer:
k = 60
Step-by-step explanation:
2k + 11 is a same side corresponding angle, hence
2k + 11 = 131 ( vertically opposite angles )
subtract 11 from both sides
2k = 120 ( divide both sides by 2 )
k = 60
Answer:
Option C. k = 60
Step-by-step explanation:
There are two lines Z and Y and crossed by a transverse x.
We have to find the value of k.
Since opposite angle of ( 2k + 11 ) is corresponding angle of 131°
so opposite angle of ( 2k + 11 ) will be = (2k + 11)
and corresponding angles are equal in measure.
So 2k + 11 = 131
2k = 131 - 11
2k = 120
k = 60
Option C k = 60 is the answer.

If f(x)=x+7 and g(x)=1/x-13, What is the domain of (f•g)(x)
Answer:
F(x) = x+7
g(x) = 1/(x-13)
fog(x) = [1/(x-13)] + 7
The denominator of the fraction cannot be equal to zero.
So, the domain of fog(x) is x∈R~{13}
Step-by-step explanation:
To find the domain of (f•g)(x), substitute g(x) into f(x) and identify any values of x that make the expression undefined.
Explanation:The function (f•g)(x) represents the composition of two functions, f(x) and g(x). To find the domain of (f•g)(x), we need to determine the values of x for which the composition is defined.
The composition (f•g)(x) can be written as f(g(x)). Substituting g(x)=1/x-13 into f(x)=x+7, we have f(g(x))=(1/x-13)+7.
The domain of (f•g)(x) consists of all the values of x for which the expression (1/x-13)+7 is defined. Since division by zero is not defined, we need to exclude x=0 from the domain. Additionally, we need to exclude the value x=13 because the expression (1/x-13)+7 would lead to division by zero. Therefore, the domain of (f•g)(x) is x≠0, 13.

Use slope formula to find the missing coordinate.
(r, 1) and (5, -7) Slope = 8/3
Answer:
r=8
Step-by-step explanation:
The formula for slope is
m = (y2-y1)/ (x2-x1)
Substitute in what we know.
8/3 = (-7-1)/(5-r)
Simplify
8/3 = -8/(5-r)
We can use cross products to help us solve.
8 * (5-r) = 3 * (-8)
divide each side by 8
8/8 * (5-r) = 3 * (-8)/8
5-r = -3
Subtract 5 from each side
5-r-5 = -3-5
-r = -8
Multiply by -1
r = 8

Step-by-step explanation:
is y=5/3x+3,20x+12y=12 a parallel, perpendicular.or a neither pair equation
Answer:
Neither
Step-by-step explanation:
y = 5/3 x + 3, this line has slope = 5/3
20x + 12y = 12
12y = -20x + 12
y = -20/12 x + 1
y = - 5/3 x + 1, this line has slope = - 5/3
Parralel ; same slopes
Perpendicular; slopes are opposite and reciprocal
So answer is neither pair parallel nor perpendicular
The pair of equations y = 5/3x + 3 and 20x + 12y = 12 are parallel because they both have the same slope of 5/3 once the second equation is put into slope-intercept form.
To determine if the pair of equations y = 5/3x + 3 and 20x + 12y = 12 are parallel, perpendicular, or neither, we must first put both equations into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. The equation y = 5/3x + 3 is already in slope-intercept form with a slope of 5/3. To convert the second equation into slope-intercept form, we can rewrite it as 12y = -20x + 12, and then y = (-20/12)x + 1, which simplifies to y = -5/3x + 1.
Now, comparing the slopes of these two lines, we see that both slopes are equal, meaning the lines are parallel to each other since they have the same slope but different y-intercepts.
