What is the solution to the system of equations below? HELP!!!! y = negative one-fourth x + 2 and 3 y = negative three-fourths x
Oxana [17]

Answer:

No solution

Step-by-step explanation:

Step 1: Write out equations

y = -1/4x + 2

3y = -3/4x - 6

Step 2: Substitution

3(-1/4x + 2) = -3/4x - 6

Step 3: Distribute

-3/4x + 6 = -3/4x - 6

From here, we can see that we have the same slope but different y-intercept. This means that the 2 lines are parallel and therefore never intersect.

Alternatively, you could graph the equations and see that the 2 lines are parallel and never intersect.

13pts HELP!
Sonja [21]

Answer:

The speed of the car is 42 miles per hour

Step-by-step explanation:

Step 1:

(Blank) x s = (Blank)

Let us evaluate this. Something times s miles per hour is going to gives us? 126 miles. So, our second blank would be 126 since that's our total:

(Blank) x s = 126

Step 2:

On the other hand, our first blank would be 3. Why? Because that's the amount of time it takes us to go 126 multiplied by s miles per hour; Our new equation is:

3 x s = 126

Step 3:

We can simplify this equation to:

3s = 126

Step 4:

We now have a one step equation. Divide each side by 3 to get s by itself.

\frac{3s}{3} =\frac{126}{3}

Step 5:

We end up getting:

s = 42

That means that the car is traveling at 42 miles per hour. If the car continues at that rate for 3 hours, the car would have traveled 126 miles.

Hope this helps!
