solve the following system of equations using substitution x+y+z=7y=32x+y-z=5enter your answer in the form of (x,y,z)

murzikaleks [220]

Given equations:

$x+y+z=7\ldots(1)$ $y=3\ldots(2)$ $2x+y-z=5\ldots(3)$

Substitute 3 for y in equation (1);

$\begin{gathered} x+3+z=7 \\ x+z=7-3 \\ x+z=4\ldots(4) \end{gathered}$

Substitute 3 for y in equation (3);

$\begin{gathered} 2x+3-z=5 \\ 2x-z=5-3 \\ 2x-z=2\ldots(5) \end{gathered}$

Adding equation (4) and (5);

$\begin{gathered} (x+z)+(2x-z)=4+2 \\ x+z+2x-z=6 \\ 3x=6 \\ x=\frac{6}{3} \\ x=2 \end{gathered}$

Substitute 2 for x in equation (4);

$\begin{gathered} 2+z=4 \\ z=4-2 \\ z=2 \end{gathered}$

Therefore, the values of (x,y,z) is (2,3,2).

What is an object doing at the moment its instantaneous acceleration is zero?

Oliga [24]

Answer: Option A

Explanation:

Acceleration is defined as the rate of change of the vellocity.

Then, if the acceleration is equal zero, the object has a constant velocity or a velocity equal to zero (also constant, of course)

Then, te correct option would be option A; resting, because an object resting has instantaneuos acceleration of zero.

What is the force of a 24.52 kg Television dropped on Pluto (acceleration of 0.59 m/s2)

inna [77]

The force of gravity on the object is 14.47 N

Explanation:

The weight of an object (which is the force of gravity experienced by an object) at a certain location is given by

$F=mg$

where

m is the mass of the object

g is the acceleration of gravity at the location of the object

IN this problem, we have:

m = 24.52 kg (mass of the object)

$g=0.59 m/s^2$ (acceleration of gravity on Pluto)

Substituting, we find the force of gravity on the object:

$F=(24.52)(0.59)=14.47 N$
