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

[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]

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:

37 dimes

Step-by-step explanation:

i was experimenting. 17 quarters and 37 dimes. 17 times .25 is 4.25. 37 times .10 is 3.70. add them and it's correct.

the cost of a donut is $2 and the equation that represents the given scenario will be:

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given, Three friends met for a book club at a coffee shop. Each friend ordered a cup of coffee and two donuts. The total of the order was $21.75.

Let " d" be the cost of a cup of coffee

and "c" be the cost of the donut

Since Each friend ordered a coffee and a donut

And there are 3 friends

Thus,

3(d + 2c) = 21.75

3d + 6c = 21.75

Also given,  a cup of coffee costs $3.25

d = 3.25

Substituting the values in equation 1

9. 75 + 6c = 21.75

6c = 12

c = 2

therefore, the cost of a donut is $2.

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:

y  = [tex]\frac{-1}{4}( x^3 + 2x^2 - 32x -96)[/tex]

Step-by-step explanation:

The function is cubic

It has roots as -4, -4 , 6

this means the value of x = -4, -4 , 6 which makes the entire equation zero

so we have solutions as

x+4 = 0

x+4 = 0

x- 6 = 0

on forming a cubic equation using these

(x+4)(x+4)(x-6)

the equation passes through (2,36)

put x = 2

(2+4)(2+4)(2-6) = (6)*(6)*(-4)

which exceeds 36 so we product the equation with -1/4 to get 36

Final equation

y = [tex]\frac{-1}{4} (x+4)(x+4)(x-6)[/tex]

  y  = [tex]\frac{-1}{4}( x^3 + 2x^2 - 32x -96)[/tex]
