How many solutions does the system have? y=−2x−4 y=3x+3

Molodets [167]

Answer:

One Solution

Step-by-step explanation:

First substitute the y in the first equation with the second equation to get

-2x-4=3x+3

since theres a variable of both sides, you subtract the variable with the least coefficient, in this case, you add 2x to both sides to get

-4=5x+3

subtract the constant on both sides to get

-1=5x

divide both sides by 5

x= -0.2 or -1/5

We can conclude that the distance from Sandy's Hotel to Trader Joes' Store is:

d = 8.06 miles

Step-by-step explanation:

From the coordinate plane, we can clearly identify that:

Sandy's Hotel is located at the point (-8, 9)

Trader Joes' Store is located at the point (-4, 2)

The distance from Sandy's Hotel to Trader Joes' Store can be calculated such as:

$d=\:\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

The distance between (-8, 9) and (-4, 2)

$d=\sqrt{\left(-4-\left(-8\right)\right)^2+\left(2-9\right)^2}$

$=\sqrt{\left(-4+8\right)^2+\left(2-9\right)^2}$

$=\sqrt{4^2+7^2}$

$=\sqrt{16+49}$

$=\sqrt{65}$

$=8.06$ miles

Therefore, we can conclude that the distance from Sandy's Hotel to Trader Joes' Store is:

d = 8.06 miles
