Answer:

Infinite solutions.

Step-by-step explanation:

−5+(−5r)+10 =-5r+5

Combine like terms

-5r +5 = -5r+5

Add 5r to each side

-5r+5r +5 = -5r+5r+5

 5 = 5

This is a true statement, so the equation has infinite solutions.


If we got a false statement, then there would be no solutions.

Answer:

Infinitely many solutions. Each real number is a solution of this equation.

Step-by-step explanation:

-5 + (-5r) + 10 = -5r + 5

5 - 5r = -5r + 5       <em>add 5r to both sides</em>

5 = 5   TRUE

Ms. Rodriguez broyght 10 oranges for afternoon snak that she needs to share evenly with the 15 players on her daughters soccer t
daser333 [38]

Answer:

she should cut them into thirds

Step-by-step explanation:

there are 10 oranges while there are 15 players.

a) if she cuts them into halves, she will have 20 slices with 5 left over, who will get an extra slice while who doesn't? it can't work  

b) if she cuts them into thirds, she will have 30 slices with 15 left over, that is enough to give each player two slices with none left over, it works!!

c) if she cuts them into quarters, she would have 40 slices with 25 left over. this means some players would get three slices, while others would only get two. it doesn't work.

this is why B is the right answer

Write the equation of the circle centered at ( 4 , − 5 ) with radius 18.
Free_Kalibri [48]

Answer:

(x-4)^2 + (y+5)^2 = 324

Step-by-step explanation:

The equation of a circle is given by the equation (x-h)^2 + (y-k)^2 = r^2, where (h,k) is the center point of the circle.

Therefore, since the center point of the circle and the radius is given, we can just plug the numbers into the formula:

(x-4)^2 + (y+5)^2 = 18^2

<u>(x-4)^2 + (y+5)^2 = 324</u>

A manufacturer of bicycles has determined that 550 bikes per month will be sold at a price of $250. At a price of $150, it is es
iogann1982 [59]

750 bikes would be sold for $350

Let x represent the number of bikes sold per month and y represent the price.

550 bikes are sold at a price of $250, this can be represented by (550, 250). Also, 750 bikes is sold at a price of $150, hence it is represented by (750, 150)

A linear function is represented by:

y = mx + b

m is the slope, b is the y intercept.

Therefore the function is:

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-250=\frac{150-250}{750-550}  (x-550)\\\\y=\frac{1}{2}x-25

The number of bikes sold for $350 is:

350 = (1/2)x - 25

x = 750

Therefore 750 bikes would be sold for $350
