Answer: 11-2x

We need to solve this using PEMDAS

P-Parentheses
E-exponents
M-multiplication
D-division
A-addition
A-subtraction

Let’s rewrite the equation

2•2-2x+7

The first thing we see here (in the order of PEMDAS) is multiplication. Let’s multiply 2•2

4-2x+7

The next thing we see here (in the order of PEMDAS) is addition. Let’s add 4 and 7.

11-2x

We cannot simplify this anymore since -2x has a variable with it. Your final equation will be 11-2x, which is still equivalent to your original expression.

Hope this helps comment below for more questions :)

About Slope - Intercept Form:

  • y = mx + b
  • m is the slope
  • b is the y-intercept

About Standard Form:

  • Ax + By = C
  • A & B & C are integers
  • A & B are both non-zero
  • This form is good to use when wanting to find the x & y intercepts of a line

About Point - Slope Form:

  • Y - Y1 = m (x -X1)
  • Y1 & X1 is a point on the line
  • The form allows you to identify the slope & the point on the line

Other Info:

  • Remember, y comes before the x  
  • An ordered pair from your problem: (-3,1), -3 is x & 1 is y & x is before the y
  • An ordered pair from your problem: (3,5), 3 is x & 5 is y & x is before the y
  • For the graph, the vertical line is y
  • For the graph, the horizontal line is x

Hope this information helps!!! :)

Find the vertex of the parabola.
Gnesinka [82]

Answer:

The vertex is (3,4)

Step-by-step explanation:

f (x) = x^2 - 6 x + 13

Completing the square

-6/2 = -3 and squaring it = 9

    = x^2 -6x +9 +4

   = ( x-3) ^2 +4

The equation is now in vertex form

a( x-h) ^2 +k

where the vertex is ( h,k)

The vertex is (3,4)
