Answer:

9

Step-by-step explanation:

65/13=5

45/5=9  The answer is 9

Answer:

19b + 10

Step-by-step explanation:

Here, we want to increase 9 by the quantity of b added to 10.

We proceed as follows;

9 increased by quantity of b is 9 + b

This added to 10 would be 9 + b + 10 = 19b + 10

Answer:

5/9

Step-by-step explanation:

Answer:

okay this is easy its 5/9

The vertices of triangle A''B''C'' are A''(-2, -1), B''(-7, 4), and C''(2, 3).

Thus, option (D) is correct.

1. Translation: The original triangle ABC is translated 2 units to the right and 3 units down to form triangle A'B'C'.

To translate a point (x, y) by (a, b), the new coordinates become

(x + a, y + b).

The coordinates of A' would be:

A' = (-3 + 2, 1 - 3) = (-1, -2)

The coordinates of B' would be:

B' = (2 + 2, -4 - 3) = (4, -7)

The coordinates of C' would be:

C' = (1 + 2, 5 - 3) = (3, 2)

2. Reflection over y = x:

Triangle A'B'C' is reflected over the line y = x to form triangle A''B''C''.

To reflect a point (x, y) over the line y = x, the new coordinates become (y, x).

The coordinates of A'' would be:

A'' = (-2, -1)

The coordinates of B'' would be:

B'' = (-7, 4)

The coordinates of C'' would be:

C'' = (2, 3)

Therefore, the vertices are A''(-2, -1), B''(-7, 4), and C''(2, 3).

Thus, option (D) is correct.

Answer:

The independent quantity is normally plotted on the horizontal (x) axis - which means that the points in the x coordinate are the domain. Since the dependent quantity is normally plotted on the vertical (y) axis, the y-coordinates make up the range.

Answer:

the 50% off is the better deal

Step-by-step explanation:

200 x .50= 100 so on the first phone you save $100

the website you get 25% off so .25 x 200=50 so 200 - 50 =150 then you get another 25% off .25 x 150 =37.50 so 150 - 37.50 = 112.50.

Answer:

Step-by-step explanation:

<a = 85° ( Vertically Opposite Angles )

<b = 180 - 85 = 95° ( Adjacent Angles )

Hope this helps

Plz mark as brainliest!!!!!!!!

Answer:

<a=85

<b=95

Step-by-step explanation:

<a is going to be the same as the other angle is across from it. So <a equals 85 degrees. So now since we know that two parts are 85 degrees we add 85 + 85 and we get 170 degrees. Since the whole thing is 360 degrees we need to subtract the 170 degrees that we already have. So 360-170 is equal to 190 degrees. Now since <b is the same as the angle across from it is we just need to divide the remaining degrees in half. So we take the 190 degrees and divide that in half. When you divide that in half you get 95 degrees. So <b is 95 degrees.

Find

  The length of each light saber, rounded up to the nearest foot.

Solution

The attached scale drawing shows the triangles with the angles and sides filled in.

The angle at the Jedi's hand is 2a = 2(37°) = 74°. If L represents the Jedi's light saber length, then the cosine relation is useful:

  Cos = Adjacent/Hypotenuse

  cos(74°) = (1.4 ft)/L

  L = (1.4 ft)/cos(74°) ≈ 5.08 ft

Rounded up to the nearest foot, the Jedi's light saber is 6 ft long.

__

The angle at Darth's hand is ...

  5c = 5(16°) = 80°

and the length of the opposite side is ...

  b/14 = 63/14 = 4.5 . . . feet

The sine relation is useful here. If L represents Darth's light saber length, then ...

  Sin = Opposite/Hypotenuse

  sin(80°) = (4.5 ft)/L

  L = (4.5 ft)/sin(80°) ≈ 4.57 ft

Rounded up to the nearest foot, Darth's light saber is 5 ft long.

Answer:

y=x+4

Step-by-step explanation:

Solve with the point-slope formula: y-y1=m(x-x1). The line is parallel; both slopes are equivalent. Plug in the coordinates we have into the formula, along with the slope from the original equation (-1). To check, we can plug the coordinates back into the equation.

y-(1)=-1(x+3)

y-1=x+3

y=x+4

Check:

(1)=(-3)+4

Answer:

4 servings

Step-by-step explanation:

Yogurt in the container = 1 5/8 pounds

A serving = 3/8 pounds

how many servings of yogurt are in the container?

Servings in the yogurt container = total yogurt in the container / yogurt per servings

= 1 5/8 ÷ 3/8

= 13/8 × 8/3

= 13/3

= 4.33

To the nearest whole serving

Answer:

(T-3)2=6

Step-by-step explanation:

Given:

The relation is

[tex]M = \{ (15k+9, 4), (3\cdot (4k-1), 6) \}[/tex]

To find:

The value of k for which the relation is not a function.

Solution:

A relation is a function if their exist a unique output or y value for each input or x values.

A relation is not a function if it has two y-values for single x value.

So, the given relation is not a function if x-coordinates of both ordered pairs are equal.

[tex]15k+9=3\cdot (4k-1)[/tex]

[tex]15k+9=12k-3[/tex]

Isolate variable terms.

[tex]15k-12k=-9-3[/tex]

[tex]3k=-12[/tex]

Divide both sides by 3.

[tex]k=-4[/tex]

Therefore, the given relation is not a function for k=-4.
