Answer:

 Number & Cost($)

 Feet & Yards

Step-by-step explanation:

  Number & Cost:

      (2, 38), (4, 76)            <====== pick any two point to find constant

      constant = (y₂ - y₁) / (x₂ - x₁)

                     = (76 - 38) / (4 - 2)

                     = 38 / 2

                     = 19             <====== k the constant

      y = kx

      y = 19x

      point (2, 38):    38 = 19(2)   ===>      38 = 38

      point (4, 76):    76 = 19(4)   ===>      76 = 76

      point (7, 133):  133 = 19(7)   ===>    133 = 133

      point (9, 171):   171 = 19(9)   ===>     171 = 171

  Feet & Yards:

      (27, 9), (75, 25)            <====== pick any two point to find constant

      constant = (y₂ - y₁) / (x₂ - x₁)

                     = (25 - 9) / (75 - 27)

                     = 16 / 48

                     = 1/3             <====== k the constant

      y = kx

      y = 1/3x

      point (3, 1):           1 = 1/3(3)      ===>     1 = 1

      point (12, 4):        4 = 1/3(12)    ===>     4 = 4

      point (27, 9):       9 = 1/3(27)   ===>     9 = 9

      point (75, 25):   25 = 1/3(75)   ===>   25 = 25

Answer:

x = √48

Step-by-step explanation:

[tex] ({3}^{ \frac{x}{2} } )( {3}^{ \frac{x}{4} }) = 3 {}^{6}[/tex]

[tex] {3}^{ \frac{x}{2} \times} {}^{ \frac{x}{4} } = 3 {}^{6} [/tex]

[tex]3 {}^{ \frac{ {x}^{2} }{8} } = 3 {}^{6} [/tex]

[tex] \frac{ {x}^{2} }{8} = 6[/tex]

[tex] {x}^{2} = 6 \times 8[/tex]

[tex] {x}^{2} = 48[/tex]

[tex]x = \sqrt{48} [/tex]

Answer:

he should budget about $51.22

Step-by-step explanation:

annual mean one year since there is 12 months in a year you would want to divide 12 to $614.66

Answer:

i think it's $51.22 Cause it said annual which means one year and it has 12 months so the actual price devide by 12

am not that sure tho cause the question is tricky

Answer:

y = -.3x + 1.5

Step-by-step explanation:

See attached Screenshot using Desmos to write equation.

Answer:

40

Step-by-step explanation:

1.Kknow the following information;

Remember, the sum of degrees of angles in a triangle is 180.

So say if a traingle contained;

<1, <2, <3,

Then:

<1 + <2 + <3 = 180

2. State the given, and set up an equation;

In this case, it is given that;

<1 = 115

<2 = 25

Therefore, set up the equation;

115 + 25 + <3 = 180

3. Solve the equation;

115 + 25 + <3 = 180

Simplify,

140 + <3 = 180

Inverse operations,

140 + <3 = 180

-140          -140

<3 = 40

Answer:

Slope is 2

Y-intercept is 7

Step-by-step explanation:

To find the slope we take any two points from the table

and use it in the formula :

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\[/tex]

we take the points (0,7) and (1,9)

now we put these points in the formula and it becomes

[tex]m=\frac{9-7}{1-0}[/tex]

[tex]m=2[/tex]

so our slope which is m is 2 and now for the y-intercept we use the standard equation

[tex]y=mx+c[/tex]

where c is the y-intercept

we use the value of m which is 2 and use any point from the table lets take (0,7)

[tex]y=mx+c\\7=(2)(0)+c\\7=c[/tex]

our y-intercept which is c is 7

so finally our slope is 2 and y-intercept is 7

Hi there!

[tex]\large\boxed{B. \text{ } x = 2(y + 3)^{2} -2}[/tex]

The transformation formula of a horizontal-facing parabola is:

x = ±a(b(y - k)) + h, where the vertex is at (h, k).

Looking at the graph, we can see a vertex at (-2, -3) with a stretch of 2. The graph is also pointed towards the RIGHT, which means that the coefficient "a" must be positive. Therefore:

The only logical answer choice is B, or x = 2(y + 3)² - 2.

The formula indicates that:

* Vertex at (-2, -3)

* Stretch of 2

* Right-facing parabola

Answer:

Answer:

(tan(theta)-1)^3

= (tan(theta)-1)(tan(theta)-1)(tan(theta)-1)

= (tan^2(theta)-2tan(theta)+1)(tan(theta)-1)

= tan^3(theta)-2tan^2(theta)+tan(theta)-tan^2(theta)+2tan(theta)-1

= tan^3(theta)-3tan^2(theta)+3tan(theta)-1

Answer:

y < 5

Step 1: Subtract 5y from both sides.

7y+2−5y<5y+12−5y

2y+2<12

Step 2: Subtract 2 from both sides.

2y+2−2<12−2

2y<10

Step 3: Divide both sides by 2.

[tex]\frac{2y}{2}[/tex]  < [tex]\frac{10}{2}[/tex]

= y < 5

Answer:

Jamil buys 6 pens.

Step-by-step explanation:

Jamil buys 4 books and each book costs £5.95. With 5.95+5.95+5.95+5.95 = £23.80. We have the total price for the books. The total cost of books and pens is £37.90 and each pen costs £2.35. If we keep adding £2.35 to our £23.80, we will get £37.90.                                                                                       If we add 23.80+2.35+2.35+2.35+2.35+2.35+2.35 = £37.90. We now have our total amount, and the prices of the amount of books and pens Jamil bought. Jamil bought 6 pens as it equals to £37.90.

Answer:

16.78 inches of fabric was used for headbands for each player and 8.81 inches of fabric was used for wristbands for each player

Step-by-step explanation:

Lane is making accessories for the soccer team.

For headbands

He uses 721.54 inches of fabric on headbands for 41 players and 2 coaches.

Hence:

Let the number of inches used for headbands be represented by x

41x + 2x = 721.54

43x = 721.54

x = 721.54/43

x = 16.78 inches

Hence the number of inches used to make head band for 1 player is 16.78 inches

He also uses 361.21 inches of fabric on wristbands for just the players.

We have 41 players hence:

41 players = 361.21 inches

1 player = x

41 × x = 1 × 361.21 inches

x = 361.21 inches/41

x = 8.81 inches

8.81 inches of fabric was used for wristbands for each player.

Hence:

16.78 inches of fabric was used for headbands for each player and 8.81 inches of fabric was used for wristbands for each player
