#19 The distance between the points (4, 1) and (9, 1) is

kirill115 [55]

Hello!

Given the two points, $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ , and to find the distance between these two points is found by using the formula:

$d = \sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}$

$(x_{1}, y_{1})$ is assigned to one the points, in this case, is (4, 1).

$(x_{2}, y_{2})$ is assigned to other point, which is (9, 1).

Then, plug in these values into the formula and solve.

$d = \sqrt{(9-4)^{2}-(1-1)^{2}}$

$d = \sqrt{5^{2}-0^{2}}$

$d = \sqrt{25}$

$d = 5$

Therefore, the distance between the two points is 5.

Four time a number r plus half a number s equals 12. Twice the number r plus one fourth of the numbers s equals 8. What are the

Snezhnost [94]

The system of equations have no solution.

Explanation:

The equations are $4r+\frac{1}{2}s=12$ and $2r+\frac{1}{4} s=8$

To find the two numbers, let us solve the equations using substitution method.

From the equation $2r+\frac{1}{4} s=8$ , let us determine the value of r,

$\begin{aligned} 2 r+\frac{1}{4} s &=8 \\ 2 r &=8-\frac{1}{4} s \\ r &=\frac{1}{2}\left(8-\frac{1}{4} s\right) \\ r &=4-\frac{1}{8} s \end{aligned}$

Let us substitute the value of r in $4r+\frac{1}{2}s=12$ , we get,

$\begin{aligned} 4\left(4-\frac{1}{8} s\right)+\frac{1}{2} s &=12 \\ 16-\frac{1}{2} s+\frac{1}{2} s &=12 \\ 16 &=12 \end{aligned}$

which is not possible.

This means that the system has no solution.
