Answer:

(3, 3)

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtract Property of Equality

Step-by-step explanation:

<u>Step 1: Define Systems</u>

x + y - 6 = 0

x - y = 0

<u>Step 2: Rewrite Systems</u>

x + y - 6 = 0

  1. Add 6 on both sides:                    x + y = 6

<u>Step 3: Redefine Systems</u>

x + y = 6

x - y = 0

<u>Step 4: Solve for </u><em><u>x</u></em>

<em>Elimination</em>

  1. Combine 2 equations:                     2x = 6
  2. Divide 2 on both sides:                    x = 3

<u>Step 5: Solve for </u><em><u>y</u></em>

  1. Define equation:                     x - y = 0
  2. Substitute in <em>x</em>:                        3 - y = 0
  3. Subtract 3 on both sides:       -y = -3
  4. Divide -1 on both sides:          y = 3

What is 7%tax of something that costs 2.99
KonstantinChe [14]
<span> For this case we can make the following rule of three:
 2.99 ----------> 100%
 x --------------> 7%
 From here, we clear the value of x.
 We have then:
</span> x = (7/100) * (2.99)&#10;
<span> Rewriting the expression we have:
</span> x = (0.07) * (2.99)&#10;&#10;x = 0.2093 $<span>
 Answer:
 The sales taxes are:
 x = 0.2093 $</span>

Lu is making a quilt that is 20 squares wide and has 18 rows the border of the quilt is made by using each toy design equally as
mixer [17]

Answer:

The correct answer is two designs are used 12 times each and other four designs are used for 13 times each.

Step-by-step explanation:

Width of the quilt Lu is making is 18 rows of 20 squares each.

Thus the perimeter of the quilt is 20 + 20 + 18 + 18 = 76.

We can also say there are 76 square as the boundary which are to be bordered with toy designs.

Each square can hold 1 design of toy and there are 6 different designs of toys.

Thus number of times each design is used \frac{76}{6} = 12 \frac{4}{6}.

Thus there are two designs used 12 times each and other four designs are used for 13 times each.

\displaystyle\int\frac{x^2+x-3}{(x^3+x^2-4x-4)^2}\,\mathrm dx

Notice that x^3+x^2-4x-4=x^2(x+1)-4(x+1)=(x-2)(x+2)(x+1). Decompose the integrand into partial fractions:

\dfrac{x^2+x-3}{(x-2)^2(x+2)^2(x+1)^2}
=\dfrac1{3(x+1)}-\dfrac{11}{32(x+2)}-\dfrac1{3(x+1)^2}-\dfrac1{16(x+2)^2}+\dfrac1{96(x-2)}+\dfrac1{48(x-2)^2}

Integrating term-by-term, you get

\displaystyle\int\frac{x^2+x-3}{(x^3+x^2-4x-4)^2}\,\mathrm dx
=-\dfrac1{48(x-2)}+\dfrac1{3(x+1)}+\dfrac1{16(x+2)}+\dfrac1{96}\ln|x-2|+\dfrac13\ln|x+1|-\dfrac{11}{32}\ln|x+2|+C
