Answer/Step-by-step explanation:

✔️Number of Yoga classes = x

Cost ($) = y

Constant of proportionality (k) = y/x

Using the pair form the table of values given, (4, 60), find the constant of proportionality:

✅k = 60/4 = 15

Equation that represents the relationship between x and y is:

y = 15x

✔️Let's complete the table.

✅When number of yoga classes (x) = 2:

Substitute x = 2 into y = 15x

Thus,

y = 15*2 = 30

That is, 2 Yoga classes will cost $30

✅When number of yoga classes (x) = 6:

Substitute x = 6 into y = 15x

Thus,

y = 15*6 = 90

That is, 6 Yoga classes will cost $90

✅When number of yoga classes (x) = 8:

Substitute x = 8 into y = 15x

Thus,

y = 15*8 = 30

That is, 8 Yoga classes will cost $120

Angle 1 and angle 2 are supplementary angles. m<1 is 4y + 7, and m<2 is Sy + 4. Find m<2.
Doss [256]

Step-by-step explanation:

First, we should define supplementary angles.

Supplementary angles are angles that add up to 180 degrees.

Since 1 and 2 are supplementary and we know their values, we just set them equal to 180 degrees

(

4

y

+

7

)

+

(

9

y

+

4

)

=

180

Now just solve for one variable

13

y

+

11

=

180

13

y

=

169

y

=

13

Now the question asks for m<2, which is

9

y

+

4

So we just plug in

9

⋅

13

+

4

=

121

So m<2 is 121

mr_godi [17]
If the original price is 'x', 60% of 'x' is $30


0.6*x = 30
30/0.6 = x
x = 50

The original price is $50

What is the rule for finding the vertex of a formula in Standard form? Use that rule to
worty [1.4K]

The vertex is the minimum or the maximum point of the parabola.

<em>x and f(x) represent the horizontal and the vertical coordinates of the vertex.</em>

<em />

The standard form of a parabola is

f(x) = ax^2 +bx + c

The x coordinate of the parabola is calculated using:

x  =-\frac{b}{2a}

The value of the x-coordinate is then plugged in, into the equation to calculate the y-coordinate, as follows:

f(\frac{b}{2a}) = a(-\frac{b}{2a})^2 + b(-\frac{b}{2a}) + c

At the end of the calculation,

x and f(x) represent the horizontal and the vertical coordinates of the vertex.

Take for instance:

f(x) = 2x^2 + 4x - 9

The x-coordinate of the vertex is:

x = -\frac b{2a}

x = -\frac 4{2 \times 2}

x = -\frac 44

x=-1

The y-coordinate is:

f(x) = 2x^2 + 4x - 9

f(-1) =2 \times (-1)^2 + 4 \times -1 - 9

f(-1) =-11

So, the vertex of f(x) = 2x^2 + 4x - 9 is (-1,11)

See attachment for illustration of vertex of f(x) = 2x^2 + 4x - 9
