Does the graph represent a function?

Answer:

x = 2

Step-by-step explanation:

2x - 3 = 9 - 4x

2x + 4x - 3 = 9

2x + 4x = 9 + 3

6x = 9 + 3

6x = 12

x = 2

Hope this helped! :)

Answer:

2

Step-by-step explanation:

You start of with the equation 2x-3 = 9-4x

Then you bring -4x to the left side, making it 6x-3 = 9

Take the -3 to the right, 6x = 12

Lastly divide 12 by 6

Answer:

96.2*10^5 gallons

Step-by-step explanation:

gallons of milk produced by 1 cow = 2.6×10^3

No. of cows with local dairy farm =  3.7×10^3

Total of gallons of milk produced by farm = gallons of milk produced by 1 cow * No. of cows with local dairy farm  = 2.6×10^3 * 3.7×10^3 = 9.62*10^6

we have to write it in standard form = 96.2*10^5 gallons

i can be also written as = 9,620,000 Gallons.

9.62 Million Gallons of milk is produced by local dairy farm Yearly.

Answer:

A) ∠9 = ∠10 = ∠11 = ∠12  = 90°

∠2 = ∠3 = ∠5 = ∠8 = 135°

∠1 = ∠4 = ∠6 = ∠7 = 45°

B) 1. ∠4 and ∠1 -> vertical angles

2. ∠7 and ∠5 -> supplementary

3. ∠9 and ∠10 -> supplementary

Step-by-step explanation:

Data

The following are vertical angles, so they are congruent:

∠1 ≅ ∠4

∠3 ≅ ∠2

∠11 ≅ ∠9

∠10 ≅ ∠12

∠7 ≅ ∠6

∠5 ≅ ∠8

From here and data, it is deduced that

∠11 ≅ ∠9 ≅ ∠10 ≅ ∠12

From the picture, the addition of them is equal to 360°, then:

∠11 + ∠9 + ∠10 + ∠12 = 360°

4*∠11 = 360°

∠11 = 360°/4

∠11 = 90° = ∠10 = ∠9 = ∠12

∠2 and ∠4 are supplementary, then:

∠2 + ∠4 = 180°

∠2 = 180° - 45°

∠2 = 135°

∠7 and ∠5 are supplementary, then:

∠7 + ∠5 = 180°

∠7 = 180° - 135°

∠7 = 45°

Answer:

C.21

Step-by-step explanation:

The value of 1/ (2x³ + 3.4y) is 1/33.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

Given:

Fraction = 1/ (2x³ + 3.4y)

We have the value x= 2 and y=5.

So,  1/ (2x³ + 3.4y)

=  1/ (2(2)³ + 3.4(5))

=  1/ (2(8) + 17)

=  1/ (16+17)

=  1/ 33

Hence, the value is 1/33.

Answer:

EH = 3.31

Step-by-step explanation:

We have been given a right angle triangle EKL. As KH has been given as the altitude (perpendicular) of the right angled triangle, and K is the right angle, we can say that EK is tthe base of the triangle and EH is the only side lleft, which is the hypotenuse of the triangle.

Where,

EK = Base = 3

KH = perpendicular altitude

EH = Hypotenuse

m<K = 90

m<E = 25

We know that

cosθ = Base/ Hypotenuse

cos 25 = 3/ EH

EH = 3/cos25

EH = 3.31

Perpendicular alitutude can also be calculated by using the formula for tanθ.

Step-by-step explanation:

In the expression, d represents the number of drinks she orders and t represents the number of toppings.

In this case, she orders 4 drinks and 3 toppings, so d = 4 and t = 3.

0.90(2.25d + 1.40t + 6)

Answer:

The correct option is A

A) y = (1/5)x + 6

Step-by-step explanation:

The equation of the first cut shown in the graph is:

y = (1/5)x - 1

We know that a general form of linear equation is given as:

y = mx + c

Comparing both equations, we get that the slope m = 1/5

As the second cut is parallel to the first cut, it will have the same slope, that is m = 1/5

Substitute it in the general linear equation

y = mx + c

y = (1/5)x + c

We know that this equation passes through the point (0,6), substitute it in  the above equation>

6 = (1/5)(0) + c

c = 6

The equation for second cut be found by using m = 1/5 and c = 6

y = mx + c

y = (1/5)x + 6

Answer:

B. 0

Step-by-step explanation:

Given

g(t) = t² - t

f(x) = 1 + x

Required

Find g(f(3) - 2f(1))

First, we'll solve for f(3)

Given that f(x) = 1 + x

f(3) = 1 + 3

f(3) = 4

Then, we'll solve for 2f(1)

2f(1) = 2 * f(1)

2f(1) = 2 * (1 + 1)

2f(1) = 2 * 2

2f(1) = 4

Substitute the values of f(3) and 2f(1) in g(f(3) - 2f(1))

g(f(3) - 2f(1)) = g(4 - 4)

g(f(3) - 2f(1)) = g(0)

Now, we'll solve for g(0)

Given that g(t) = t² - t

g(0) = 0² - 0

g(0) = 0 - 0

g(0) = 0

Hence, g(f(3) - 2f(1)) = 0

From the list of given options, the correct answer is B. 0

Answer:

B, C, and F

Step-by-step explanation:

There's a certain universal property that we must all understand whenever we apply division: we can never divide by 0. This would be considered undefined.

Look at the answer choices.

- B says 0/0, which is dividing by 0, so this is one of our answers.

- C says -8/0, which is also dividing by 0, so this is another one of our answers.

- Finally, F says 11/0, which is dividing by 0, so this is our last answer.

Thus, the answers are B, C, and F.

Number 1: To find number 1 use hypotenuse theory. 180-(69+31) is the equation. After you solve it you get m<1 as 80.

Number 2: Since you already found m<1 find the other angle across from it.

Equation is: 180-80, which equals to 100.

Then once you have two angles use the theory again: 180-(100+45)=35.

Therefore m<2=35.

Number 3: Still using m<1, 180-100=80. Now you have to angles you get the equation:

180-(80+47), which equals to 53. Therefore m<3=53

Answers: m<1=80; m<2=35; m<3=53

Answer:

1= 80

2= 35

3= 33

Step-by-step explanation:

First start by solving for angle 1. A triangle is always equal to 180 degrees so if you know triangle 1 has an angle equal to 69 degrees and another angle equal to 31 degrees then all you would need to do is add them up (this equals 100) and subtract that sum from 180 to find the difference (it's 80.)

Now that you know angle 1 is equal to 80 you can solve angle 2 and 3. When there are intersecting lines, the angles across from each other are always equal. So, it is safe to assume that the angle across from angle 1 is also 80 degrees. This will help us figure out the other angles in triangles 2 and 3. These four intersecting angles will equal 360, therefore because angle 1 and the angle across from it equal 80 degrees, then what we can do is add up 80+80 (which equals 160) then subtract that from 360 (which equals 200.) Because the two undetermined center angles are equal to each other, we can simply divide 200 by 2 to get 100.

Now that we know that triangle 2 has angles equal to 45 and 100 degrees, and triangle 3 has angles equal to 47 and 100 degrees, we can figure out what angles 2 and 3 are. To find angle 2 we will add 45 and 100 to get 145, then we'll subtract it from 180 like before to get 35. To find angle 3 we will add 47 and 100 to get 147, then we'll subtract it from 180 like before to get 33.

Answer:

A decrease of 9.2% is 1 - 0.092 = 0.908. 0.908 * 721.45 = 655.08.

Answer:

721.45 x 9.2% = 721.45 x 0.092 = 66.37

so 66.37 is the discount

721.45 - 66.37 = 655.08

So 655.08 is the discounted price

655.08 is the answer

Step-by-step explanation:

Given

The figure above

Required

Calculate the y component

Represent the y component with y, the resultant vector with s and the angle with [tex]\theta[/tex]

The y component of a vector (as it is, in this case) is calculated as thus;

[tex]sin\theta = \frac{y}{s}[/tex]

[tex]Where\ \theta = 15\\ s = 80[/tex]

Substituting these values in the equation

[tex]sin\theta = \frac{y}{s}[/tex] becomes

[tex]sin\ 15= \frac{y}{80}[/tex]

Multiply both sides by 80

[tex]80 * sin\ 15= \frac{y}{80} * 80[/tex]

[tex]80 * sin\ 15= y[/tex]

[tex]80 * 0.2588190451= y[/tex]

[tex]20.705523608 = y[/tex]

[tex]y = 20.705523608[/tex]

Answer:

See below.

Step-by-step explanation:

To be a function the graph must pass the vertical line test. If any of the vertical lines which can be drawn intersects the graph more than once then it's not function.

So Graph 1 is not a function because a vertical line passes through the 2 points in quadrant 1, whereas Graph 2 is a function because any vertical line you can draw only passes through the graph once.

Graph 3 - not a function.

Graph 4 - not a function.

Graph 5 - not a function.

Graph 6 is a function.

And there are 5 congruent triangles in the pentagon so

Answer:

If an image of a triangle is congruent to the pre-image, then the scale factor of the dilation must be n = 1. Dilating an image with a dilation factor of 1 will result to the same image and that ensures the congruency between the pre-image and the dilated image.
