Answer:

(-5, 2)

Step-by-step explanation:

<u>plug x into the equation x - 5y = -15</u>

-5 - 5y = -15

add 5 to both sides: -5y = -10

divide by -5: y = 2

Tell whether the ordered pair is a solution of the equation<br> y=5x; (15,-3)
n200080 [17]

Answer:

This ordered pair is NOT a solution of the equation.

Step-by-step explanation:

First, it is important to note that ordered pairs consist of (x, y) so in this case

x = 15 and y = -3.  And that any variable directly next to a number calls for multiplication.  So, plugging in the variables the equation would look like

"-3 = 5 x 15"  

To see if 5 x 15 = -3 we will multiply them.  5 x 15 actually equals 75 not -3.  So we know this ordered pair is NOT the solution for the problem.

Acceleration of 10kg Maas's pushed by a 5n force
malfutka [58]

Answer:

<h3>The answer is 0.5 m/s²</h3>

Step-by-step explanation:

To find the acceleration of an object given it's mass and the force acting on it can be found by using the formula

acceleration =  \frac{force}{mass}  \\

From the question

force = 5 N

mass = 10 kg

So we have

acceleration =  \frac{5}{10 }  =  \frac{1}{2}  \\

We have the final answer as

<h3>0.5 m/s²</h3>

Hope this helps you

A population of 110,000 grows 5% per year for 14 years. How much will the population be after 14 years?
Fantom [35]

Answer:

Since it is growing at 5% per year, at the end of each year the population will be 1.05 times what is was at the start of the year.

 

Start with 110,000 and multiply by 1.05 a total of 16 times to get the population at the end of 16 years.

 

P = 110,000 x 1.0316 ≅ 176,518
