Answer:

(y,z)=(3,5)\\\\ |(y,z)|=\sqrt{34}

Step-by-step explanation:

Given y(3, 1), z(0, 4)

-The ordered pair is written by summing their corresponding coordanates as below:

(y,z)=y(3,1)+z(0,4)\\\\=(3+0,1+4)\\\\=(3,5)

-We then calculate the magnitude of this ordered pair as following:

|y,z|=\sqrt{y^2+z^2}\\\\=\sqrt{3^2+5^2}\\\\=\sqrt{34}\\\\\therefore |(y,z)|=\sqrt{34}

Hence, the magnitude of the ordered pair is \sqrt{34}

Plz help i need answer.
In-s [12.5K]

Answer:

C

Step-by-step explanation:

Make a system of equations.

Justin = j

Greg = g

j + 15 = g

g/2 + 75 = j

We can substitute.

(j + 15)/2 + 75 = j

j/2 + 15/2 + 75 = j

j/2 = 165/2

j = 165

Substitute back into j + 15 = g

165 + 15 = g

g = 180
