Answer:

10 classes

Step-by-step explanation:

Given equations in the question

Dance World: y = 15x

Toe Tappers: y = 25 + 12.5x

Where,

x = number of classes

Equate the total cost at both dance studios

15x = 25 + 12.5x

Collect like terms

15x - 12.5x = 25

2.5x = 25

Divide both sides by 2.5

2.5x / 2.5 = 25 / 2.5

x = 10 classes

x = number of classes = 10

Open up and have a minimum

Step-by-step explanation:

If the x² coefficient is:

Positive, the graph will open up and have a minimum

Negative, the gaph will open down and have a maximum

Answer:

opens up and has a minimum

Step-by-step explanation:

Provided a is not 0, y=ax^2+bx+c will be a parabola.

The parabola will open up and have a minimum if a is positive.

The parabola will open down and have a maximum if a is negative.

Since 1/2 is positive, then your parabola opens up and has a minimum.

Answer:

Percentage increase = 36%

Step-by-step explanation:

Kitten's weight = 640 grams

Adult's weight = 2918 grams

To find the percentage increase in the kitten's weight;

We will calculate the increase using the formula;

[tex] Increase = original \; number - new \; number [/tex]

Substituting the values, we have;

Increase = 2918 - 640 = 2278

Mathematically, percentage increase is calculated using the following formula;

[tex] Percentage \; increase = \frac{increase}{original \; number} * 100[/tex]

[tex] Percentage \; increase = \frac{2278}{640} * 100[/tex]

[tex] Percentage \; increase = 3.56 * 100[/tex]

Percentage increase = 35.5 ≈ 36%

Answer:

[tex]\dfrac{a+b+c}{a} =7[/tex]

Step-by-step explanation:

Given :-

And we need to prove that ,

So let us assume that ,

[tex]\dfrac{a+b}{3} =\dfrac{b+c}{6} =\dfrac{c+a}{5}=k[/tex]

Where k is a constant . Now equate each of the three terms separately to k . Therefore we have ,

[tex]\implies a + b = 3k \quad \dots (i) [/tex]

Similarly we can say that ,

[tex]\implies c + b = 6k \quad \dots (ii)[/tex]

[tex]\implies a + c = 5k\quad \dots (iii) [/tex]

Subtracting (i) and (ii) :-

Adding (iv) and (iii) :-

[tex]\implies 2c = 4k [/tex]

[tex]\implies \boxed{c = 4k }[/tex]

Put this is (ii) :-

[tex]\implies b +4k = 6k [/tex]

[tex]\implies \boxed{b= 2k }[/tex]

Similarly we will get ,

[tex]\implies \boxed{a = k }[/tex]

Proving the given equation :-

[tex]\implies \dfrac{a+b+c}{a} \\\\\implies \dfrac{k+2k+4k}{k} \\\\\implies \dfrac{7k}{k}=\boxed{\red{ 7}}[/tex]

Hence proved !

Answer:

b = 225

Step-by-step explanation:

multiply both members by 15

15 x 15 = (b/15)x 15

b = 225

Answer:

225

Step-by-step explanation:

if b divided by 15 equals 15, multiply 15 by 15 and you get 225

Answer:

f = 2

Step-by-step explanation:

equate the log

therefore,

2f + 4 = 14 - 3f

collect like terms

2f + 3f = 14 - 4

5f = 10

divide through by 5

f = 10/5

f = 2

Answer:

x = -5

Step-by-step explanation:

each curve will get increasingly closer to -5 but never reach it

if you look at the function, f(x) = 3/(x+5),  x≠ -5 because then the denominator would be zero and that is never possible

The vertical asymptote of the function will  be [tex]x=-5[/tex].

A vertical asymptote is a vertical line i.e. as approaches from either the positive or negative side, the function approaches infinity. Vertical asymptotes occur at the values where a rational function has a denominator of 0.

We have,

[tex]f(x)=\frac{3}{x} +5[/tex]

So,

As the above definition says,

A Vertical asymptote of a function is a vertical line [tex]x=k[/tex], where [tex]f(x)[/tex] becomes unbounded.

So,

Vertical asymptote for given figure and given function is ,

[tex]x=-5[/tex],

Hence we can say that the vertical asymptote of the function will  be [tex]x=-5[/tex].

Answer:65

Step-by-step explanation:

Answer: 6 rooms

Step-by-step explanation:

3/8 rolls of wire are needed to wire a room in a house. If there are a total of 2¹/₄ rolls of wires, the number of rooms that could be wired is:

First convert to an improper fraction:

2¹/₄ = 9/4 rolls of wire

Total number of rooms that can be wired are:

= Total amount of wire available / Wires per room

= 9/4 ÷ 3/8

= 9/4 * 8/3

= 72 / 12

= 6 rooms

Answer:

t = -14

Step-by-step explanation:

(t + 8)( - 2) =12

(t)(-2) + (8)(-2) = 12

-2t + -16 = 12

(subtract to make -16 positive)

-2t - 16 = 12

+16 +16

(add 16 to both sides. 16 and 12)

-2t = 28

(divide)

-2t = 28

/-2 /-2

t = -14
