Answer:

The answer is 4 r 1.

Step-by-step explanation:

We kbow that 9 time 4 will get us 36, so that's what we put in the two boxes below the 37. Then, we subtract 36 from 37 and get 1. The one will go in the box below the 36. This means our answer will be 4 r 1. Hope this helps :)

Solve - 4x2 - 4x - 9 = 0, stating your solutions in the form a = bi. Someone please answer!!
PIT_PIT [208]

Answer:

x=-0.5 \pm -i\sqrt{2}

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

  • Standard Form: ax² + bx + c = 0
  • Quadratic Formula: x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}

<u>Algebra II</u>

  • Imaginary Roots: √-1 = i
  • Standard Form: a + bi

Step-by-step explanation:

<u>Step 1: Define</u>

-4x² - 4x - 9 = 0

a = -4

b = -4

c = -9

<u>Step 2: Find roots</u>

  1. Substitute:                    x=\frac{4\pm\sqrt{(-4)^2-4(-4)(-9)} }{2(-4)}
  2. Exponents:                   x=\frac{4\pm\sqrt{16-4(-4)(-9)} }{2(-4)}
  3. Multiply:                        x=\frac{4\pm\sqrt{16-144} }{-8}
  4. Subtract:                       x=\frac{4\pm\sqrt{-128} }{-8}
  5. Factor:                          x=\frac{4\pm \sqrt{-1} \cdot \sqrt{128} }{-8}
  6. Simplify:                       x=\frac{4\pm 8i\sqrt{2} }{-8}
  7. Factor:                          x=\frac{4(1\pm 2i\sqrt{2}) }{-8}
  8. Divide:                          x=\frac{1\pm 2i\sqrt{2}}{-2}
  9. Expand:                        x=\frac{-1}{2} \pm \frac{-2i\sqrt{2} }{2}
  10. Simplify:                        x=\frac{-1}{2} \pm -i\sqrt{2}
  11. Evaluate:                      x=-0.5 \pm -i\sqrt{2}

PLEASE HELP QUICK 100 POINTS
MrRissso [65]

Answer:

Change per week: $20

Starting amount of money: $550

Step-by-step explanation:

<u>Given equation</u>:

y=550+20x

where:

  • x = number of weeks
  • y = total account balance

<u>Change per week</u>

As the variable x represents the number of weeks, its coefficient represents the change per week in the amount of money.

Therefore, the change per week in the amount of money in the account is $20.

<u>Initial Balance</u>

The starting amount of money in the account (initial balance) will be the value of y when x = 0:

\implies y=550+20(0)=550

Therefore, the starting amount of money in the account is $550.

A relation is (also) a function if every input x is mapped to a unique output y.

In terms of graphical representation, this implies that a graph represents a function if there doesn't exist a vertical line that intersects the graph more than once. So:

  1. The first graph is exactly a vertical line, so it's not a function.
  2. The second graph represents the function y=x, so it's a function: you can see that every possible vertical line crosses the graph only once.
  3. The third graph is not a function, because you can draw vertical lines that cross the graph twice.
  4. Similarly, in the fourth graph you can draw vertical lines that cross the graph twice
  5. The fifth graph is a function, because every vertical line crosses the graph once
  6. The last graph is a function, although discontinuous, for the same reason.
