Answer:

(x-2)^2

Step-by-step explanation:

The blue graph is shifted two units to the right of the "original" function x^2 (red). Let's recall the vertex form of a quadratic:

a (x-h)^2 + k

where a represents a constant that describes the opening of the parabola (up/down); h represents horizontal shift; and k represents vertical shift.

The blue graph is two units to the right (+2), there is NO vertical shift and NO change in how the parabola opens.

So, let's plug the appropriate values into vertex form:

(x-(+2))^2

= (x-2)^2

\bf (1-2i)^2\implies (1-2i)(1-2i)\implies 1-2i-2i+(2i)^2 \\\\\\ 1-4i+(2^2i^2)\implies \stackrel{\textit{recall }i^2=-1}{1-4i+(4\cdot -1)}\implies 1-4i-4\implies \boxed{-3-4i}

David pays a 20% income tax on his $2,100 salary. How many dollars is the tax?
Ganezh [65]
20% of 2100 is 420

Answer:

  • \boxed{\sf{x=24}}

Step-by-step explanation:

<u>GIVEN:
</u>

To find the missing number in the proportion, you have to isolate it the term of x from one side of the equation.

\sf{\dfrac{8}{7}=\dfrac{x}{21}  }

First, thing you do is switch sides.

\sf{\dfrac{x}{21}=\dfrac{8}{7}  }

Multiply by 21 from both sides.

\Longrightarrow: \sf{\dfrac{21x}{21}=\dfrac{8*21}{7} }

Solve.

Multiply the numbers from left to right.

Use the order of operations.

PEMDAS stands for:

  • Parentheses
  • Exponents
  • Multiply
  • Divide
  • Add
  • Subtract

\Longrightarrow: \sf{\dfrac{8*21}{7}=\dfrac{168}{7}=24 }

\Longrightarrow: \boxed{\sf{x=24}}

  • <u>Therefore, the final answer is x=24.</u>

I hope this helps. Let me know if you have any questions.
