Solve by substitution 3x+y=5 and 2x-y=10

prohojiy [21]

3x+5=2x-10
-2x -2x
X+5=-10
-5 -5
X=-15

3(-15)+y=5
-45+y=5
+45 +45
y=50

2(-15)-y=10
-30-y=10
+30 +30
-y=40
Divide by -1 on both sides
y=-40

Which complex number has a distance of V17 from the origin on the complex plane?

Nataly_w [17]

Answer:

$4-i$

Step-by-step explanation:

Use the formula for the distance of a complex number from the origin on the complex plane.

$\sqrt{a^2+b^2}$

$a+bi$

$4-i$

$\sqrt{4^2-i^2}$

$\sqrt{4^2+(-1)^2}=\sqrt{16+1}=\sqrt{17}$

The complex number that has a distance of $\sqrt{17}$ is $4-i$ .
