Answer:

A and C

Step-by-step explanation:

For any relation to be considered a function, each domain value (x-value) must have exactly one range value (y-value). If a relation contains an x-value that has two or more y-value related/mapped to it, the relation is not a function.

Let's examine each option given.

Option A: each x-value has exactly one y-value related or assigned to it. Therefore, the relation is A FUNCTION.

Option B: the x-value, 4, has two y-values, 12 and 15 assigned to it. Therefore, the relation is NOT A FUNCTION.

Option C: each x-value has exactly one y-value related or assigned to it. Therefore, the relation is A FUNCTION.

Option D: the x-value, 1, has two y-values, -1 and 1 assigned to it. Also, x-value, 3, has two y-values, 2 and -2 assigned to it. Therefore, the relation is NOT A FUNCTION.

Answer:

Please find attached the required plot of the reflection of ABC across line l

Step-by-step explanation:

The reflection of the coordinates of the points of a preimage across a line is given by points with distances on the other side of the line of the same length as the distances of the coordinates of the points of the preimage are from the given line;

Therefore, the image of the preimage is drawn by selecting points on the other side of the reflecting line that are equidistant from the line as the points of the preimage, and that are directly (vertically) opposite the points on the other side of the line as shown in the attached graph drawn with Microsoft Word

Answer:

I think the answer is 9 feet

Step-by-step explanation:

Answer:

The answer is 20 feet by 20 feet. Let's solve the equation: (x – 8)^2 = 144. (x - 8)^2 = 12^2. Since a^2 = b^2 is the same as a = b, then (x - 8)^2 = 12^2 can be simplified to: x - 8 = 12. Now, solve for x. x = 8 + 12. x = 20. Therefore, the dimensions of the original lawn were 20 feet by 20 feet.

Answer:

C. m<XYA > m<ZYA.

Step-by-step explanation:

Since XY = YZ, as indicated in the information given, the angles opposite XY and YZ would also be of equal measure of degrees.

Thus, XA = 5. The angle opposite XA is m<XYA.

ZA = 3. The angle opposite ZA is m<ZYA.

Since XA > ZA, therefore,

m<XYA > m<ZYA.

Answer:

12d = 156

Step-by-step explanation:

Carlos is reading 12 pages / day

The total amount to read is 156

In order to find the days, you have to divide 156 by 12 or

Equation:

12d = 156; furthermore

d = 13 days, meaning it will take 13 days to read 156 pages.

Answer:

A. 12d = 156

Step-by-step explanation:

The book has a total number of 156 pages. If he reads 12 pages per night, we need to multiple the total number of days by the amount he reads per night in order to get 156. Since we don't know how many days it will take, we will use d to represent the amount of days. So, the equation ends up looking like this:

12d = 156

d represents the amount of days it will take for Carlos to read the book.

Answer:

The measure of Q is 116

Step-by-step explanation:

For a Rhombus, opposite angles are equal

so angle R is 64 too

Now, we should understand that the diagonals bisect the angles

So the angles in the triangle QTR are

Q + 32 + 32 = 180

Q = 180-64

Q = 116 degrees

Answer:

choice b

Step-by-step explanation:

Answer:

4 divided by 2/3 (4 ÷ 2/3) = 6

Step-by-step explanation:

When you divide one number by another , this is the same as multiplying that one number by the reciprocal of that other number. So a/b = a × 1/b = a × b^-1.

Also a reciprocal is the same as taking something to the power of -1.

When you take the reciprocal of a fraction, just flip the numerator, and denominator.

b^-1 = 1/b.

b^-n = 1/b^n.

(a/b)^-1 = b/a

a/b^-1 = ab

Therefore 4 / (2/3) = 4 × 3/2 = 12/2 = 6.

Answer:

This conjecture is false. There is a counterexample that would prove this conjecture false.

Step-by-step explanation:

Given the conjecture that if you multiply two numbers, then the product is greater than either number is very false. There is a counterexample that would prove this conjecture false.

The counter example is as shown;

Let the two numbers be 1 and 2.

Take their product;

1(2) = 2

We can see that their product which is 2 although greater than 1 is not greater than the other number but equal to it. This example therefore counter the conjecture. This is applicable to numbers with 1 included.

Answer:

  12,859,905 hamburgers

Step-by-step explanation:

Each conversion factor has a value of 1, but changes units. That is, the value of the numerator is the same as the value of the denominator, but expressed in different units.

We choose the representation of the conversion factors to cancel units we don't want and give us units we do want.

  [tex]\$1\,000\,000=\$1\,000\,000\times\dfrac{2\text{ week}}{\$725.77}\times\dfrac{5\text{ day}}{1\text{ week}}\times\dfrac{8\text{ h}}{1\text{ day}}\times\dfrac{350\text{ burgers}}{3\text{ h}}\\\\=\dfrac{1\,000\,000\times2\times5\times8\times350}{725.77\times3}\text{ burgers}\approx\boxed{12\,859\,905\text{ burgers}}[/tex]

Answer:

9700 milliliters

Step-by-step explanation:

9.7 liters is equivalent to 9,700 milliliters.

To convert liters to milliliters, we need to multiply the given value by 1,000 since there are 1,000 milliliters in 1 liter.

So, to convert 9.7 liters to milliliters, we multiply 9.7 by 1,000:

9.7 liters * 1,000 = 9,700 milliliters.

Therefore, 9.7 liters is equivalent to 9,700 milliliters.

The conversion from liters to milliliters involves shifting the decimal point three places to the right since each milliliter is 1/1,000th of a liter. This conversion is essential when dealing with smaller units of volume and allows for more precise measurements in contexts such as laboratory experiments or pharmaceutical dosages.

Answer: weight of elephant has smaller percent error.

Step-by-step explanation:

Percent error = [tex]\dfrac{|\text{estimated value -actual value}|}{\text{actual value}}]\times100[/tex]

Estimated weight of elephant  =  10,000 pounds

Actual weight of elephant = 12,400 pounds

Percent error of weight = [tex]\dfrac{|12400-10000|}{12400}\times100\%\approx19.35\%[/tex]

Estimated weight of hippopotamus  =  2,500 pounds

Actual weight of hippopotamus = 3,600 pounds

Percent error of weight = [tex]\dfrac{|2500-3600|}{3600}\times100\%\approx30.55\%[/tex]

Since 19.35 < 30.55

hence, weight of elephant has smaller percent error.

Answer:

  40°

Step-by-step explanation:

Triangles QRS and QTS are congruent (HL), so the marked angles are also congruent:

  3x +2 = 4x -4

  6 = x

Then the total angle measure of angle RST is ...

  (3x +2) +(4x -4) = 7x -2 = 7(6) -2 = 40 . . . degrees

m∠RST = 40°
