Which statement describes the mapping?
Group of answer choices

A. The mapping does not represent y as a function of x, because two of the x-values corresponds to the same y-value.

B. The mapping represents y as a function of x, because each y-value corresponds to exactly one x-value.

C. The mapping does not represent y as a function of x, because there are more x-values than different corresponding y-values.

Answer:

The diagonal stripes would require a total of 34 feet of tape.

Step-by-step explanation:

You have six hypotenuses, and you can use the Pythagorean theorem to get their lengths.

The total length of the two big diagonals then is:

2×√(36 + 36)

and the total length of the four small diagonals is

4 ×√(9 + 9)

so the total length is:

2√72 + 4√18

= 12√2 + 12√2

= 24√2

≈ 33.9

Answer:

the value of x is 25 degrees

Step-by-step explanation:

Here, we want to get the value of x

we use an important triangle angular principle here

And the principle is that when we add two opposite interior angles, we get the value of the exterior angle on the third side

Thus, mathematically;

x + 75 = 4x

4x-x = 75

3x = 75

x = 75/3

x = 25 degrees

Answer:

Alex is reading faster by 5 more pages per hour.

Step-by-step explanation:

Alex's rate of reading is 1/2 pages per minute, or 1 page every 2 minutes. To convert his rate to pages per hour, we can divide 60 (minutes in an hour) by 2 (minutes it takes Alex to read a page) which is equal to 30 (pages read in an hour). Therefore, Alex is reading at 30 pages an hour and reading 5 more pages an hour than Sammie.

Answer: (12, 5)

Step-by-step explanation:

3x + 2y = 46 x + y = 17

Subtract y from both sides of the equation.

x = 17 − y 3x + 2y = 46

Replace all occurrences of x with 17 − y in each equation.

   51 − y = 46

x = 17 − y

Solve for y in the first equation.

Move all terms not containing y to the right side of the equation.

Subtract 51 from both sides of the equation.

   −y = 46 − 51

   x = 17 − y

Subtract 51 from 46.

   −y = −5

   x = 17 − y

Multiply each term in −y = −5 by −1

Multiply each term in −y = −5 by −1. (−y) ⋅ −1 = (−5) ⋅ −1

   x = 17 − y

Multiply (−y) ⋅ −1.

   y = (−5) ⋅ −1

   x = 17 − y

Multiply −5 by −1.

y = 5

x = 17 − y

Replace all occurrences of y with 5 in each equation.

Replace all occurrences of y in x = 17 − y with 5. x = 17 − (5)

y = 5

Simplify 17 − (5).

Multiply −1 by 5.

x = 17 − 5

y = 5

Subtract 5 from 17.

x = 12

y = 5

The solution to the system is the complete set of ordered pairs that are valid solutions.

Answer:

2*2=4

Step-by-step explanation:

Answer:

x = 45.6

Step-by-step explanation:

NOTE: Please double-check my answer.

To find x, I used Sine Law.

[tex]\frac{x + 5}{sin65}[/tex] = [tex]\frac{x}{sin40}[/tex]

(x+5)sin40 = xsin65

xsin40+ 5sin40 = xsin65

xsin40 - xsin65 = -5sin40

x(sin40 - sin65) = -5sin40    (I factored out the "x")

x = [tex]\frac{-5sin40}{sin40 - sin65}[/tex]

x = [tex]\frac{-3.725565802}{0.74511316 - 0.826828679}[/tex]

x = 45.6

Answer:

[tex]A=15\ cm^2[/tex]

Step-by-step explanation:

Given that,

The height of the cuboid = 6 cm

The volume of the cuboid = 90 cm²

We need to find the area of the shaded face.

The volume of a cuboid is given by the formula as follows :

[tex]V=A\times h[/tex]

A is area of the shaded face

Putting all the values,

[tex]A=\dfrac{V}{h}\\\\A=\dfrac{90}{6}\\\\A=15\ cm^2[/tex]

So, the area of the shaded face is [tex]15\ cm^2[/tex].

Step-by-step explanation:

to find the number of couches in the partially filled truck, divide 119 by 9

119/9 = 13.2222

so 13 cars will contain 9 couches packed fully

number of trucks partially filled = 119 - (13 x 9) = 2

Answer:

123 if your going to the nearest whole number

Step-by-step explanation:

Since

6 : 7 = X : 143

Then we know

6/7 = X/143

Multiplying both sides by 143 cancels on the right

143 × (6/7) = (X/143) × 143

143 × (6/7) = X

Then solving for X

X = 143 × (6/7)

X = 122.57142857143

Therefore

6 : 7 = 122.57142857143 : 143

Answer:

18%

Step-by-step explanation:

Express the ending population as a percentage of the starting population:

270000 divided by 330000=0.82

0.82 *100=82

subtract from the 100% we started with to get the percent decrease:

100% - 82% = 18

Answer:

[tex]y = \frac{3}{2} x + 13[/tex]

Step-by-step explanation:

1) Use point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to find the slope-intercept form (or y = mx + b form) of the equation. m represents the slope, and [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects. So, substitute [tex]\frac{3}{2}[/tex] for m, -4 for [tex]x_1[/tex], and 7 for [tex]y_1[/tex]. Then, simplify and isolate y on the left side like so:

[tex]y-(7) = \frac{3}{2} (x - (-4)) \\y -7 = \frac{3}{2} (x + 4) \\y - 7 = \frac{3}{2} x + 6\\y = \frac{3}{2} x + 13[/tex]

Step-by-step explanation:

[tex] \tt{3x + 8 = 2x - 8}[/tex]

We want to get all the constants on the right hand side of the equation. So , Add 8 on both sides of the equation.

⤏ [tex] \tt{3x + 8 + 8= 2x - 8 + 8}[/tex]

⤏ [tex] \tt{3x + 16 = 2x}[/tex]

Move 2x to left hand side and change it's sign. Similarly , Move 16 to right hand side and change it's sign :

⤏ [tex] \tt{3x - 2x = - 16}[/tex]

Since , 3x and 2x are like terms , they can be added or subtracted. Subtract 2x from 3x :

⤏ [tex] \sf{x = - 16}[/tex]

[tex] \red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{x = - 16}}}}}}}[/tex]

Answer:

C: 75%

Step-by-step explanation:

27 out of 36 are red.  You find the percentage by diving 27 by 36 and then moving the decimal place over to the right 2 spaces.  27 / 36 = .75

Step-by-step explanation:

By Exterior Angle Theorem, the sum of the 2 inner angles of the triangle is equal to the exterior angle by a straight line.

Therefore we have x + 72° = 90° + 34°.

=> x + 72° = 124°, x = 52°.

Hence the value of x is 52°.

Answer:

For 1 copy it takes 5 seconds, for 2 copy it takes 7 seconds, and for 3 copy it takes 9 seconds.

For each copy, it takes 2 seconds more.

Step-by-step explanation:

A teacher is making multiple copies of a 1-page homework assignment. The time it takes her in seconds is 2 times the number of copies she makes plus 3. What is the total number of seconds it takes for the teacher to make 1 copy? 2 copies? 3 copies? By how many seconds does the total time increase for each copy?

Let the number of copies represented by x and y is the time taken.

The time It takes her in seconds is 2 times the number of copies she makes plus 3.

So the required equation is [tex]y=2x+3[/tex].

To calculate the time taken for the first copy put x=1 in the above equation.

[tex]y=2(1)+3[/tex]

[tex]y=5[/tex]

To calculate the time taken for the first copy put x=2 in the above equation.

[tex]y=2(2)+3[/tex]

[tex]y=7[/tex]

To calculate the time taken for the first copy put x=3 in the above equation.

[tex]y=2(3)+3[/tex]

[tex]y=9[/tex]

Hence, For each copy, it takes 2 seconds more.
