Answer:

x=-5

Step-by-step explanation:

-2x-41=5x-6

-35=7x

-5=x

Hello there!

-2x - 41 = 5x - 6

Move the 41 over by adding 41 to both sides.

-2x = 5x + 35

Move the 5x by subtracting it from both sides.

-7x = 35

Divide by -7 to get x.

-7/-7 = 35/-7

x = -5  

Therefore, x would equal -5.

Answer:

My Question was  The slope of the line shown between the points (-7, -3) and (-4, 0) is equal to its slope between the points (0, 4) and (6, 10).

Which of the following best describes triangle TUV and triangle XYZ?

answer: Triangle TUV is similar to triangle XYZ.

Step-by-step explanation:

Point V is at (-7, -3), and point T is at (-4, 0). So, the slope of the line between (-7, -3) and (-4, 0) is equal to the ratio of UT to VU.

Point Z is at (0, 4), and point X is at (6, 10). So, the slope of the line between (0, 4) and (6, 10) is equal to the ratio of YX to ZY.

Since the slope between (-7, -3) and (-4, 0) is equal to the slope between (0, 4) and (6, 10), the ratio of UT to VU is equal to the ratio of YX to ZY.

Two right triangles are similar if the ratios of two sets of their corresponding sides are congruent. Therefore, triangle TUV is similar to triangle XYZ.

Answer:

(15, 11)

Step-by-step explanation:

(I'm assuming you are solving for x and y.)

Plug in the x equation:

4(2y - 7) + y = 71

8y - 28 + y = 71

9y - 28 = 71

9y = 99

y = 11

Then plug that answer into the other equation:

x = 2(11) - 7

x = 22 - 7

x = 15

You can check by doing the following to make sure you are right:

15 = 2(11) - 7

15 = 22 - 7

15 = 15

4(15) + 11 = 71

60 + 11 = 71

71 = 71

Image and dimension of each bottle is attached

Answer:

Cyclinder = 572.56 cm³

Sphere = 381.70 cm³

Cone = 190.86 cm³

Step-by-step explanation:

Here, the manager ordered for three different shapes, which are: a sphere, cylinder and a cone. We are told to find the volume of each.

For the cylinder:

Given:

Radius, r = 4.5 cm

Height, h = 9 cm

The formula for calculating the volume of a cylinder is:

V = Base * height

Where base = πr²  

= π * 4.5² = 63.62

Therefore,

V = 63.62 * 9

V = 572.56 cm³

For sphere:

Given:

Radius, r = 4.5 cm

Formula for volume of a sphere is:

[tex] V = \frac{4}{3} * \pi r^3 [/tex]

[tex] = \frac{4}{3} * \pi 4.5^3 [/tex]

= 381.7 cm³

For cone:

Given:

Radius, r = 4.5 cm

Height, h = 9 cm

The formula for calculating the volume of a cone is:

V = ⅓ * Base * height

Where base = πr²  

= π * 4.5² = 63.62

Therefore,

V = ⅓*63.62 * 9

V =  190.86 cm³

Therefore the volume of perfume each bottle can carry is:

Cyclinder = 572.56 cm³

Sphere = 381.7 cm³

Cone = 190.86 cm³

Answer:

This proves that f is continous at x=5.

Step-by-step explanation:

Taking f(x) = 3x-1 and [tex]\varepsilon>0[/tex], we want to find a [tex]\delta [/tex] such that [tex]|f(x)-14|<\varepsilon[/tex]

At first, we will assume that this delta exists and we will try to figure out its value.

Suppose that [tex]|x-5|<\delta[/tex]. Then

[tex]|f(x)-14| = |3x-1-14| = |3x-15|=|3(x-5)| = 3|x-5|< 3\delta[/tex].

Then, if [tex]|x-5|<\delta[/tex], then [tex]|f(x)-14|<3\delta[/tex]. So, in this case, if [tex]3\delta \leq \varepsilon[/tex] we get that [tex]|f(x)-14|<\varepsilon[/tex]. The maximum value of delta is [tex]\frac{\varepsilon}{3}[/tex].

By definition, this procedure proves that [tex]\lim_{x\to 5}f(x) = 14[/tex]. Note that f(5)=14, so this proves that f is continous at x=5.

y=

Answer:

[tex]x= \frac{-23}{5}, y=\frac{-1}{5}[/tex]

Step-by-step explanation:

3x + y = -14

-2x + y = 9

We'll try to find x

(-2x + y = 9) multiplied by -1 => -1(-2x+y=9) = 2x-y = -9

3x + y = -14

+2x -y = -9

+__________

3x + 2x +y -y = -14 - 9

5x = -23

x = -23/5

3x + y = -14  =>And now we can find y. Just plug in -23/5 for x

[tex]3\frac{-23}{5} + y = -14[/tex]

[tex]\frac{-69}{5} + \frac{5y}{5} = \frac{-70}{5}[/tex]

[tex]\frac{5y}{5} =\frac{-1}{5}[/tex]

5y = -1

y = -1/5

Answer:

t = 66.4 minutes ( to the nearest tenth of a minute)

it would take the element 66.4 minutes to decay to 11 grams

Step-by-step explanation:

Given;

Initial amount N = 510 g

Final amount Nt = 11 g

Half life t(1/2) = 12 minutes

The amount of time t required for the Element X to decay from N to Nt can be written as;

t = ln(Nt/N) ÷ -λ .....1

Where;

λ = decay constant

λ = ln(2)/t(1/2)

Substituting λ, equation 1 then becomes;

t = ln(Nt/N) ÷ -(ln(2)/t(1/2))

Substituting the values;

t = ln(11/510) ÷ -(ln(2)/12)

t = −3.8365 ÷ -0.05776

t = 66.419

t = 66.4 minutes ( to the nearest tenth of a minute)

Answer:

(32, 16)

Step-by-step explanation:

Since the scale factor is 4, you always multiply both coordinate places (x and y) by this number.

The coordinates of one of the new vertices is (32, 16). Therefore, option D is the correct answer.

Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor. The new figure obtained after dilation is called the image and the original image is called the pre-image.

Given that, rectangle with vertices A(-6, 4), B(8, 4), C(8, -2) and D(-6, -2).

Here, the scale factor is 4

So,

(-6,4)  by a scale factor of 4(-6, 4)=(-24, 16)

(8, 4)  by a scale factor of 4(8, 4)= (32, 16)

(-6, -2) by a scale factor of 4(-6, -2)= (-24, -8)

(8, -2) by a scale factor of 4(8, -2)= (32, -8)

Therefore, option D is the correct answer.

There are 24 students in the class. Take 2/3 of this to get (2/3)*24 = 16

A more detailed step by step would be

(2/3)*24 = (2/3)*(24/1) = (2*24)/(3*1) = 48/3 = 16

The result 16 is smaller than the original number 24. This is expected because 2/3 is smaller than 1. The key thing here is that the result 16 is a whole number.

You can think of 2/3 as the approximate percentage 66.7%, so you're applying roughly 66.7% to the entire class to get 16 people who like hip hop.

It appears you're thinking in reverse when you went from 24 to 36, because 2/3 of 36 is 24, but not the other way around. Keep in mind there are 24 students total in the class, and we can't go higher than this. We can't say there are 36 people who like hip hop.

So to answer the question, yes it is possible Gertrude's survey is correct because 2/3 of 24 is a whole number.

Answer:

D.

Step-by-step explanation:

For a relation to be a function, one input cannot have multiple outputs.

In D, we can see that the input x = 1 will yield y = 4 and y = 1. So which one is it?

We cannot determine that, so this relation is not a function.

Answer:

5 dozen Donuts

7 dozen bagels

Step-by-step explanation:

5 * 9 = 45

7 * 8 = 56

56 + 45 = 101

Answer: He bought 5 dozen donuts

Step-by-step explanation:

d + b = 12   where d is the number of donuts and b is the number of bagels.

9d + 8b= 101  now solve the two equations using the elimination method

-9d - 9b =-108

9d  + 8b = 101

        -1b = -7

  b = 7

9d + 8(7)= 101

Answer:

Step-by-step explanation:

The given function is

[tex]h(x)=-x^{2} +6x+16[/tex]

Where [tex]x[/tex] is the number of burgers and [tex]h[/tex] the measure of happiness.

To find the maximum burgers needed to reach the maximum happiness, we just need to find the vertex of this function, which is defined as

[tex]V(h,k)[/tex] where [tex]h=-\frac{b}{2a}[/tex], and [tex]b=6[/tex], [tex]a=-1[/tex], replacing these values, we have

[tex]h=-\frac{6}{2(-1)}=3[/tex]

[tex]k=f(3)=-(3)^{2} +6(3)+16=-9+18+16=25[/tex]

Therefore, there are needed 3 burgers to reach the maximum measure of happiness of 25.

Using the maximum function relation, the maximum number of cheeseburgers to be consumed would be 25

Given the function :

The function is maximum at [tex] \frac-{b}{2a}[/tex]

b = 6 ; a = - 1

Hence, we have :

[tex] x = \frac-{6}{2(-1)} = 3 [/tex]

Substitute x = - 3 into the function :

h(-3) = - (3)² + 6(3) + 16

h = - 9 + 18 + 16

h = 25

Therefore, the maximum number of cheeseburgers to be tanken would be 25

what it stands for:

I = amount of interest

P = principal amount ($1,200)

R = interest rate (in years)(3% into decimal which would be .03)

Linear equations can have zero, one or infinite solutions.

If Emma tested two values (3 and 5) for the same equation and they were both true solutions, this means that the equation has more than one solution.

If a linear equation has more than one solution, than the equation has infinite solutions.
