Answer:

the system of equation has infinite solution

Step-by-step explanation:

5x_1 + x_2 = 0 , 25x_1 + 5x_2 = 0

Solve the first equation for x_2

Subtract 5x1 on both sides

5x_1 + x_2 = 0

x_2 =-5x_1

Now substitute -5x1 on second equation

25x_1 + 5x_2 = 0

25x_1 + 5(-5x_1)= 0

25x_1-25x_1= 0

0=0

So the system of equation has infinite solution

Answer:

Step-by-step explanation:

The system of linear equations is expressed as

5x1 + x2 = 0 - - - - - - - - - - - 1

25x1 + 5x2 = 0 - - - - - - - - - - 2

The first step is to eliminate x2 by multiplying equation 1 by 5 and equation 2 by 1. It becomes

25x1 + 5x2 = 0

25x1 + 5x2 = 0

The next step is to subtract equation 2 from equation 1, it becomes

25x1 - 25x1 + 5x2 - 5x2 = 0

0 = 0

The system of equations has an infinite number of solutions. This means that for as many values of x that satisfies equation 1, they will also satisfy equation 2.

Transform the equation to isolate x: ax = bx + 1. How is
shepuryov [24]

Answer:

x=\frac{1}{a-b}

The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.

Step-by-step explanation:

The given expression is ax-bx+1

We factor the left hand side to get:

(a-b)x=1

We divide both sides by: a-b

x=\frac{1}{a-b}

Observe that the difference of a and b is in the denominator.

The whole is of the form: x\propto \frac{1}{a-b}

The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.

The table shows how an elevator 500 feet above the ground is descending at a steady rate.
Snezhnost [94]
We are given that the elevator is descending, so the coefficient of t must be negative. The elevator's initial position is 500 feet above the ground, so this is a positive value of +500. Therefore the only choice that fits these is h(t) = -5t + 500.

John should drive to his workplace and back to home. On the way to the workplace it was raining, so he drove at speed of 42mph.
elixir [45]

Answer:

47.25 mph

Step-by-step explanation:

Represent the total distance traveled as 2x. Average speed= total distance/total time

When going at 42 mph, the time would be x/42 and when going at 54 mph the time would be x/54 to travel x distance. Add x/42 and x/54 together to get 16x/378. Then divide 2x by 16x/378 to get 47.25 mph. Also this is RSM innit?
