Answer:

One cup of lemonade will cost $2.

Step-by-step explanation:

From simple observation and visual inspection we can conclude that one cup of lemonade costs $2.

If 9 cups of lemonade cost $18 then one cup of lemonade will cost $18÷9 = $2

If 2 cups of lemonade cost $4 then one cup of lemonade will cost $4÷2 = $2.

Therefore we can conclude that one cup of lemonade will cost $2.

Answer:

small boxes = 5 and large boxes = 10

Step-by-step explanation:

Given:

The volume of each small box is 7 cubic feet.

volume of each large box is 13 cubic fee.

There were twice as many large boxes shipped as small boxes shipped.

Total volume of all boxes was 165 cubic feet.

Question asked:

The number of small boxes shipped and the number of large boxes shipped?

Solution:

Let  number of small boxes shipped = x

Then, the number of large boxes shipped = 2x (given)

Total volume of all boxes = 165 cubic feet.

no. of small boxes [tex]\times[/tex] vol. of each small box +  no. of large boxes [tex]\times[/tex] vol. of each large box =  165 cubic feet. (Total volume of all boxes)

[tex]x \times7 + 2x \times 13 = 165\\7x + 26x = 165\\33x = 165[/tex]

Dividing both side by 33

[tex]x = \frac{165}{33}\\ x = 5[/tex]

The number of small boxes shipped = [tex]x[/tex] = 5

The number of large boxes shipped = 2 [tex]x[/tex] = 2[tex]\times[/tex] 5 = 10

3x - 2y = 4...multiply by 2

--------------------------

-6x - 3y = -15 (result of multiplying by -3)

6x - 4y = 8 (result of multiplying by 2)

-7y = - 7 <===== here is one mistake.....its -7, not 7

y = -7/-7

y = 1

now sub 1 in for y in either of ur original equations to find x

not sure why u r multiplying again on ur paper when all u have to do is sub

2x + y = 5

2x + 1 = 5

2x = 5 - 1

2x = 4

x = 4/2

x = 2

solution is : (2,1)

the bad part about elimination is if there is a mistake made in the first part, it carries through to the end. So it is always best to check ur answers.

Final answer:

Using the properties of similar triangles and the given side lengths, we solve for x and find that ED equals 8 units.

Explanation:

We're dealing with a geometry problem involving parallel lines and the properties of triangles. Since sides AB and CD are parallel, and triangles ABE and DCE share a common vertex at E, we can find the length ED using similar triangles and the given side lengths. The corresponding sides of similar triangles are proportional, so:

AB / AE = CD / ED
9 / (2x + 4) = 6 / (x + 4)

To solve for x, cross multiply and obtain the equation:

9(x + 4) = 6(2x + 4)
Then solve for x:
9x + 36 = 12x + 24
3x = 12
x = 4
Having x, we can find ED:
ED = x + 4 = 4 + 4 = 8 units

The valid sample for the survey would be students in Natasha’s social studies class and parents who live within a 2-mile radius of Natasha’s school.

The students in Natasha's social studies class are directly affected by the speed limit in front of her school, and the parents who live nearby are likely to have an opinion on the matter as well.

While the other options may provide some insight, they are not as directly relevant to Natasha's goal of determining the neighborhood's support for lowering the speed limit.

Therefore, Equation of line and the slope is

[tex]y=-2x[/tex]

[tex]Slope = -2[/tex]

Step-by-step explanation:

Given:  

Let,  

point A( x₁ , y₁) ≡ ( 3 ,-6)

point B( x₂ , y₂ )≡ (-1 , 2)

To Find:  

Equation of Line AB =? ( Assumption)

Solution:  

Equation of a line passing through a points A( x₁ , y₁) and point B( x₂ , y₂ ) is given by the formula Two -Point Form,  

[tex](y-y_{1})=\dfrac{y_{2}-y_{1} }{x_{2}-x_{1} }\times (x-x_{1})[/tex]  

Now on substituting the slope and point A( x₁ , y₁) ≡ ( 3 , 6) and B( x₂ , y₂ )≡ (-1 , 2) we get  

[tex](y-(-6))=\dfrac{2--6}{-1-3}\times (x-3)\\\\y+6=\dfrac{8}{-4}(x-3)\\\\y+6=-2(x-3)\\y+6=-2x+6\\y=-2x[/tex] .....Required Equation of line

Which is also in the form of

[tex]y=mx[/tex] ....Also called as Equation of line Passing through Origin.

where , m =slope

Therefore, Equation of line and the slope is

[tex]y=-2x[/tex]

[tex]Slope = -2[/tex]

To find the equation of a line passing through two given points, calculate the slope using the slope formula, and then substitute the slope and one of the points into the point-slope form of a line equation. The line passing through the points (3,-6) and (-1,2) is given by the equation y = -2x + 6.

To find the equation of the line that passes through the points (3, -6) and (-1, 2), we use the formula for the slope, denoted as 'm': m = (y2 - y1) / (x2 - x1).

Then, we substitute the given pair of points into this formula to find the slope: m = (2 - -6) / (-1 - 3) = 8 / -4 = -2.

After obtaining the slope, we use the point-slope form of an equation of a line, which is y - y1 = m(x - x1). Substitute one of the given points (3, -6) and the slope -2 in: y - -6 = -2(x - 3).

Simplify this to get the final equation: y = -2x + 6.

Answer:

Step-by-step explanation:

Using the initial value a = 16 and the common ratio r = 1/4, we can use the equation for the sum of an infinite geometric series as |r| < 1:

S = a / (1-r)

  = 16 / (1-(1/4))

  = 16 / (3/4)

  = 64/3

The sum of the series is 64/3.

A geometric sequence is one where each phrase is discovered by multiplying the term before it by the same number.

The given series is 16 + 4 + 1 +...

Note that each term of the series is 1/4 of the preceding term, therefore, the series is a geometric series with a common ratio of r = 1/4.

The sum of an infinite geometric series is:

s= a/(1-r)

s= 16/(1-1/4)

s = 64/3

Hence, the sum of the series is 64/3.

Step-by-step explanation:

The standard form of the line is [tex]6y-x=30[/tex]

Step-by-step explanation:

The equation of the line in this problem, written in the point-slope form, is

[tex]y=\frac{1}{6}x+5[/tex] (1)

We want to rewrite it in the standard form with integers, that means in the form

[tex]ax+by=c[/tex]

where a, b and c are integer numbers.

We start by manipulating eq.(1), by multiplying both terms of the equation by 6:

[tex]6y = \frac{1}{6}x\cdot 6+5\cdot 6\\6y=x+30[/tex]

Now we subtract [tex]-x[/tex] on both sides:

[tex]6y-x = x-x+30[/tex]

So we find

[tex]6y-x=30[/tex]

This is a zero solution example, because you can see that both equations are the same on the left, yet different on the right.

Infinite solution example

4y=4-6x

This is an infinite solution example because if you look at both equations, you can see that they are exactly the same.

One solution example

If a system a infinite solutions, that means that the lines overlap

If a system has no solutions, that means that the lines never touch, or that they are parallel

If a system has one solution, it means that the lines intersect at one point.

A system of two linear equations in two variables can have 0, 1, or infinitely many solutions. The number of solutions can be determined without graphing by comparing the slopes and y-intercepts of the equations. If the slopes are equal and y-intercepts are different, the system has no solution. If the slopes are equal and y-intercepts are equal, the system has infinitely many solutions. If the slopes are not equal, the system has exactly one solution.

One example of a system of two linear equations in two variables with 0, 1, or infinitely many solutions is:

Equation 1: 2x + 3y = 8

Equation 2: 4x + 6y = 16

To determine the number of solutions in this system without graphing, we can use the concept of slopes. If the slopes of the two lines are equal and the y-intercepts are also equal, then the system has infinitely many solutions. If the slopes are equal but the y-intercepts are different, then the system has no solution. If the slopes are not equal, then the system has exactly one solution.

In this example, both equations have the same slope of ½; however, the y-intercepts are different. Therefore, this system has no solution.

This reveals that the two lines in the graph of this system are parallel and will never intersect.

Answer:

Option B) triple the height

Step-by-step explanation:

The rest of the question is the container has a shape of the cylinder and the options to select the answer.

The options are:

A) triple the radius

B) triple the height

C) triple the diameter

D) triple the circumference

=========================================

the container has a shape of the cylinder

The volume of the cylinder is = π r² h

It is required to choose which option is suitable so change the dimensions so that the volume is tripled.

So, the volume will be V' =  ( 3 π r² h )

Check the options:

A) triple the radius

The new radius = 3r

∴ V = π (3r)² h = 9 π r² h

B) triple the height

The new height = 3h

∴ V = π r² (3h) = 3 π r² h

So, it is no need to check the other options.

The answer is option B

Note: both of option C and D will lead to the same result of option A
