Vsevolod [243]

Answer:

When the number of sessions is equal to 10, the total cost is the same in the two plans

Step-by-step explanation:

Let

y ---> the total cost

x ---> the number of sessions

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

Planet Fitness

we have

The slope is equal to

$m=\$30\ per\ session$

The y-intercept or initial value is equal to

$b=\$50$

substitute

$y=30x+50$ ----> equation A

Gold's Gym

we have

The slope is equal to

$m=\$10\ per\ session$

The y-intercept or initial value is equal to

$b=\$250$

substitute

$y=10x+250$ ----> equation B

Equate equation A and equation B

$30x+50=10x+250$

solve for x

$30x-10x=250-50\\20x=200\\x=10$

therefore

When the number of sessions is equal to 10, the total cost is the same in the two plans

Sphinxa [80]

Question is incomplete, complete question is given below.

The numerator of a fraction is 9 and the denominator is 6. All of the following numbers are equivalent except _____.

A) 2/3

B)3/2

C)1 1/2

D)18/12

Answer:

A) 2/3

Step-by-step explanation:

Given:

The fraction is $\frac{9}{6}$

By solving the above fraction to its simplest form we get

$\frac{9}{6}=\frac{3\times3}{2\times2}=\frac{3}{2}$

Now For Option A which is $\frac{2}{3}$

Give fraction is $\frac{3}{2}$

We can say that it is Not equivalent to given fraction.

Now For Option B which is $\frac{3}{2}$

Give fraction is $\frac{3}{2}$

We can say that it is equivalent to given fraction.

Now For Option C which is $1\frac{1}{2}$

Solving above equation to simplest form we get,

$1\frac{1}{2}= \frac{1\times2+1}{2}=\frac{3}{2}$

Give fraction is $\frac{3}{2}$

We can say that it is equivalent to given fraction.

Now For Option D which is $\frac{18}{12}$

Solving above equation to simplest form we get,

$\frac{18}{12}= \frac{6 \times 3}{6 \times 2} = \frac{3}{2}$

Give fraction is $\frac{3}{2}$

We can say that it is equivalent to given fraction.

Hence all answer B C and D are all equal to $\frac{3}{2}$ except A which is $\frac{2}{3}$

Find the equation of the quadratic function that passes through the

KATRIN_1 [288]

Answer:

$y = \frac{7}{6} x^{2} - 7\frac{2}{3} x + \frac{17}{2}$

Step-by-step explanation:

$y = ax^{2} + bx + c\\2 = a + b + c\\-4 = 9a + 3b + c\\12 = 49a + 7b + c\\$

Let's eliminate the c. Take the second and subtract the first. Take the third and subtract the first.

$-6 = 8a+2b\\10=48a+6b\\$

Now take 3 times the first and subtract from the second.

$28 = 24a\\a = \frac{7}{6}$

Substitute back to calculate b.

$b=-7\frac{2}{3}$

Substitute back to calculate c.

$c=\frac{17}{2}$
