Answer:

x=-5

Step-by-step explanation:

4-2(x+7)=3(x+5)

Distribute

4 - 2x -14 = 3x +15

Combine like terms

-2x-10 = 3x+15

Add 2x to each side

-2x -10 +2x = 3x+2x+15

-10 =5x+15

Subtract 15 to each side

-10-15 =5x-15+15

-25 = 5x

Divide each side by 5

-25/5 = 5x/5

-5 =x

U're goal is to get k alone.
So divide both sides by 9/10.
3/2 divided by 9/10 is 5/3

A movie theater is located on a map of a city represented by a coordinate plane. The location of the movie theater is at (−4, 2)
Romashka [77]

See the graph

<h2>Explanation:</h2>

Remember to write complete questions in order to get good and exact answers. Here you haven't provided any option, but it's easy to plot this point on a coordinate system in order to know the location of the movie theater. We know that this theater is at the point:

(-4,2)

So let's plot this point in the cartesian plane:

  • The x-coordinate is -4
  • The y-coordinate is 2.

So the graph is shown below. Remember that the horizontal axis is called the x-axis while the vertical axis is called the y-axis.

  • x > 0 for the x-values to the right of the origin.
  • x < 0 for the x-values to the left of the origin.
  • y > 0 for the y-values above the origin
  • y < 0 for the y-values below the origin.

Solve the system of eqautions <br> y=x2-5x+7 , y=2x+1
IgorC [24]

Answer:

Step-by-step explanation:

The system of equations is given as

y=x^2-5x+7 - - - - - - - - - - 1

y=2x+1 - - - - - - - - - - - - - - 2

We would equate equation 1 to equation 2, it becomes

x^2-5x+7 = 2x+1

x^2-5x+7- 2x - 1 = 0

x^2-5x+7- 2x - 1 = 0

x^2 - 5x - 2x + 7 - 1 = 0

x^2 - 7x + 6 = 0

We would use the factorization method of solving quadratic equations.

x^2 - 6x - x + 6 = 0

x(x - 6) - 1(x - 6)

(x - 6)(x - 1) = 0

x - 6 = 0 or x - 1 = 0

x = 6 or x = 1

Substituting both values of x into equation 2, it becomes

For x = 6,

y=2×6 + 1 = 12 + 1 = 13

y = 13

For x = 1,

y=2 × 1 +1 = 2 + 1 = 3

y = 3
