Answer:

y = -3 (x + 6)   when graphed with the given equation, will form a system that has no solution

Step-by-step explanation:

Given line equation: y=-3x+6

We are supposed to find Which equation, when graphed with the given equation, will form a system that has no solution.

We know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept.

General equation of line = y=mx+c

A)y = 3 x + 6

So, Slope = 3

B)y = -3 (x + 6)

y=-3x-18

So, slope=-3

C)y=-3(x-2)

y=-3x+6

So, Slope = -3

D)y=3(x-2)

Slope =3

So, B has the same slope but different intercept

So,y = -3 (x + 6)   when graphed with the given equation, will form a system that has no solution

On Monday, jack and Jill walked from their house up the hill to get to the bus stop. They walked 4 yards every three seconds. Wr
never [62]

Answer: Our required equation will be

3d=4t

Step-by-step explanation:

Since we have given that

Jack and Jill walked 4 yards every three seconds

As we know that

Speed=\frac{Distance}{Time}\\\\Speed=\frac{4}{3}\text{ yards per seconds}\\

Now, we need to find the find the equation to represent  the distance,<em>d</em>,

Jack and Jill walked over time <em>t </em>.

So here it is,

Distance=Speed\times Time\\\\d=\frac{4}{3}\times t\\\\d=\frac{4}{3}t\\\\3d=4t

Hence, our required equation will be

3d=4t
