How many solutions does the equation 3x + 6 = −1 − 3 + 4x have? (5 points)
lianna [129]

Answer:

The equation has only one solution which is:

  • x = 10

Step-by-step explanation:

Given the equation

3x\:+\:6\:=\:-1\:-\:3\:+\:4x

Let us solve the equation to determine the type of the equation

3x\:+\:6\:=\:-1\:-\:3\:+\:4x

subtract the number: -1 - 3 = -4

3x+6=4x-4

subtract 6 from both sides

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

3x=4x-10

subtract 4x from both sides

3x-4x=4x-10-4x

-x=-10

Divide both sides y -1

\frac{-x}{-1}=\frac{-10}{-1}

x=10

Therefore, the equation has only one solution which is:

  • x = 10

Answer ASAP!!! Find the distance on the coordination system from the point (-3,4) to the point (8,-7).
alexdok [17]

Answer:

The answer to your question is: distance = 15.55 units

Step-by-step explanation:

Data

A (-3, 4)

B (8, -7)

Formula

distance = √((x2-x1)² + (y2-y1)²)

Substitution

distance = √((8- -3)² + (-7-4)²)

distance = √((8 + 3)² + (-7-4)²)

distance = √((11)² + (-11)²)

distance = √(121 + 121)

distance = √242

distance = 15.55 units
