Answer:

(-1, 1)

Step-by-step explanation:

Hi there!

We want to solve the system of equations given as:
2x-3y=-5

3x+y=-2

Let's solve this equation by substitution, where we will set one variable equal to an expression containing the other variable, substitute the expression as the variable that it equals, solve for the other variable (the variable that the expression contains), and then use the value of the solved variable to find the value of the first variable
In the second equation, we have y by itself; therefore, if we subtract 3x from both sides, then we will get an expression that y is equal to.

So subtract 3x from both sides

y=-3x-2

Now substitute -3x-2 as y in the first equation.
It will look something like this:

2x - 3(-3x-2)=-5

Now do the distributive property.

2x+9x+6=-5

Combine like terms

11x+6=-5

Subtract 6 from both sides

11x=-11

Divide both sides by 11

x=-1

Now substitute -1 as x in the equation y=-3x-2 to solve for y:

y=-3(-1)-2

multiply

y=3-2

Subtract

y=1

The answer is x=-1, y=1; this can also be written as an ordered pair, which would be (-1, 1)
Hope this helps!

HELP DUE IN 5 MInUTes ASAp
musickatia [10]

Answer:

The expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is \mathbf{Speed=\frac{100}{20} }

Step-by-step explanation:

We are given:

Distance = 100 m

Time = 20 s

We need to find:

Speed

The formula used is: Speed=\frac{Distance}{Time}

Putting values and finding the expression

Speed=\frac{Distance}{Time}\\Speed=\frac{100}{20}

So, the expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is \mathbf{Speed=\frac{100}{20} }

<em>Note: Kindly recheck your options, As option B is not written correctly.</em>
