\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
A&({{ 1}}\quad ,&{{ 5}})\quad 
%  (c,d)
B&({{ 4}}\quad ,&{{ 1}})
\end{array}\qquad 
%  distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}
\\\\\\
AB=\sqrt{(4-1)^2+(1-5)^2}\implies AB=\sqrt{3^2+(-4)^2}
\\\\\\
AB=\sqrt{9+16}\implies AB=\sqrt{25}\implies AB=5

If 8x−4y=20 and 4x−8y=4, what is the value of x−y?
____ [38]

Answer:

Step-by-step explanation:

Solve the system:

8x−4y=20

4x−8y=4

Reduce the first equation by dividing every term by -2:

-4x + 2y = -10

and then combine this result with the second equation:

4x−8y=4

-4x + 2y = -10

--------------------

      -6y = -6, and so y = 1.  

According to the first equation, if y = 1, then 4x - 8 = 4, or x = 3.

Then x = 3 and y = 1.

So, finally, x - y = 3 - 1 = 2

Use 1% or 10% to estimate 93% of 149<br><br> A. 169.5<br> B. 13.5<br> C. 112<br> D. 135
irakobra [83]
93% of 149

10% of 149 = 14,9

93% of 149 > 90% of 149

93% of 149 > 149 - 14,9 ≈ 149-15≈134
                   > 134
⇒ the answer is D
