5x + 3y = 22
y = 2x

Substitute y=2x into the first equation

5x + 3(2x) = 22
5x + 6x = 22
11x = 22
x = 2

Hope that helps :)

$\text{We have the ecuation:} \ 5x+3y=22 \\ \text{We know:}\ y=2x \\***********************\\5x+3*(2x)=22 \\ 5x+6x=22\\11x=22\\ \boxed{\bold{x=2}} \\\\ \boxed{\text{The answer is : x=2}} \\\\ \boxed{y=2*2=4}$

Find the distance between (3,4) and (4,-6) if necessary, round to the nearest tenth.

Ratling [72]

Answer:

The distance is:

d = 10.0 units (Rounded to the nearest the Tenths Place)

Step-by-step explanation:

Given the points

(3,4)

(4,-6)

The distance 'd' between (3,4) and (4,-6)

$\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):$

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

substituting the points values

$=\sqrt{\left(4-3\right)^2+\left(-6-4\right)^2}$

$=\sqrt{1+10^2}$

$=\sqrt{1+100}$

$=\sqrt{101}$

$=10.0$ units (Rounded to the nearest the Tenths Place)

Thus, the distance is:

d = 10.0 units (Rounded to the nearest the Tenths Place)
