Answer:29

Step-by-step explanation:

If you memorize these like me, you would know its 29. Otherwise, just use the pythagorean theorem, 20^2 +21^2 =841

sqrt(841) = 29.

Well, we know that it costs $60 plus 5 per month for Alpha Fitness Club.

We also know that it costs $20 plus 10 per month for Omega Fitness Club.

In order to find out which one would cost the most, we must add the additional costs to the original join cost.

(NEVER add the join cost, just do the join cost at the beginning or else the clubs will never become the same cost.)

Club M1 M2 M3 M4 M5 M6 M7 M8 M9

Alpha: 60 65 70 75 80 85 90 95 100

Omega:20 30 40 50 60 70 80 90 100

If you look above, you realize that there is a time when they both cost the same.

Summary sentence:

After 9 months, the cost to belong to either fitness club would be $100.

Five years from now, the sum of the ages of a women and her daughter will be 40 years. The difference in their present age is 24

Tomtit [17]

Answer:

Daughter age = 3 years

Step-by-step explanation:

Let x be the age of the women and y be the age of the daughter.

Given:

After five year the sum of the women and daughter age = 40

$(x+5)+(y+5)=40$

At present the sum of the women and daughter age

$x+5+y+5=40$

$x+y+10=40$

$x+y=40-10$

$x+y=30$ --------------(1)

So the sum of the present age is $x+y=30$

The difference in their present age is 24 years.

$x-y=24$

$x=24+y$

Now we substitute x value in equation 1.

$(24+y)+y=30$

$24+2y=30$

$2y=30-24$

$2y=6$

$y=\frac{6}{2}$

$y=3\ years$

Therefore, the daughter age is 3 years.

Graph the linear equation

baherus [9]

For the equation
.. x - y = 4
you can divide by 4 to put the equation into intercept form. This form shows you both interecepts at once.
.. x/4 +y/(-4) = 1

The x-intercept is (4, 0).
The y-intercept is (0, -4).

The graph is shown below.
