Which ordered pairs in the form (x, y) are solutions to the equation

Remember that a solution to an equation is a coordinate pair that makes a true statement.

So, for each of these coordinate pairs, plug in the x coordinate for the x in your equation and the y coordinate for the y in your equation.

Example:
5x + 3y = 8;
which of these is a solution? 
(1,1)
(-3, 2)

For each coordinate pair provided, I'm going to plug it back into my original equation:

SO: for (1,1)
5x + 3y = 8
5(1) + 3(1) = 8
5 + 3 = 8
8 = 8 <--- This is a true statement. (1,1) IS a solution to this equation.

For (-3,2)
5x + 3y = 8
5(-3) + 3(2) = 8
-15 + 6 = 8
-9 = 8 <---- This is NOT a true statement. (-3,2) is not a solution to this equation.

You have to do the same thing!! Plug each of your answer choices into your original equation. Solve it out. If you end up with a TRUE statement, the coordinate pair IS a solution. If you end up with a FALSE statement, the coordinate pair is NOT a solution!

The table shows the height of an object, h(t), in meters after t seconds. Use your calculator to find the quadratic function. Fi
padilas [110]
My calculator models the function as
.. h(t) = -4.9t^2 +23.4t +120

The maximum height is reached at t=-23.4/(2(-4.9)) ≈ 2.39 seconds.

X and Y together can do a piece of work in 10 days and X alone can do it in 15 days would Y alone can finish the work ?​
Ratling [72]

Answer:

<em>Y alone can do the piece of work in 30 days.</em>

Step-by-step explanation:

<u>Proportions</u>

Let's make:

N = days for Y to finish the work alone

Since X alone can do it in 15 days, each day he can do a proportion of 1/15 of the piece of work.

Since Y alone can (possibly) do it in N days, each day he can do 1/N parts of the work.

Together, they do

\displaystyle \frac{1}{15}+\frac{1}{N}

parts of the work per day. We know they can finish it in 10 days, thus:

\displaystyle \frac{1}{15}+\frac{1}{N}=\frac{1}{10}

Rearranging:

\displaystyle \frac{1}{N}=\frac{1}{10}-\frac{1}{15}

The LCM of 10 and 15 is 30, thus operating:

\displaystyle \frac{1}{N}=\frac{3-2}{30}=\frac{1}{30}

Solving for N:

N = 30

Y alone can do the piece of work in 30 days.
