Hey!

Hope this helps...

Product Property: <span>Sometimes also referred to as the <em>Zero Product Property</em>, states that if AB=0 , than A=0 and/or B=0.</span>

Example: If AB=0, than A=0 and/or B=0.

Quotient Property: <span>Sometimes also referred to as the Quotient <em>of Powers Property</em>, states that when you have the same base, you subtract the exponents.</span>

Example: (5^3)/(5^7) = 5^-4 OR 1/(5^4)

Negative Exponent: <span>This simply means "<em>How many times I you divide by that number?</em>"</span>

Example: 5^-3 = 5/5/5 = 0.2

Power of a Power Property: <span>Sometimes also referred to as the <em>Product of Powers Property</em>, states that rather than adding the exponents of that base, you multiply them instead. This is the way to find the single exponent of the base.</span>

Example: 5^3^3 = 5^(3*3*3) = 5^27

Power of a Product Property: For this property, rather than multiplying the exponents of the same base, you add them instead.

Example: 5^3 * 5^15 = 25^18

A system of equations is graphed on a

Ira Lisetskai [31]

Answer:

(1, 4)

Step-by-step explanation:

$\text{It looks as if "they" are asking you to solve the problem graphically.}\\\text{Then, you must solve each equation for y, plot a few points for each graph,}\\ \text{and see where each graph intersects. }$

$\begin{array}{rcl}(1) & 2x + 3y = 12 & \\& 3y = 12 - 2x& \text{Subtracted 2x from each side}\\ & y = 4 - \dfrac{2}{3}x & \text{Divided each side by3}\\\\(2) & 4x + 2y =10& \\& 2y = 10 - 4x& \text{Subtracted 2x from each side}\\ & y = 5 - 2x & \text{Divided each side by 2}\\\end{array}\\$

Below are a few points for Equations (1) and (2).}

$\begin{array}{cc|cc}\mathbf{x} & \mathbf{y} & \mathbf{x} & \mathbf{y}\\0 & 4 & 0 & 5\\& & 1 & 3\\& & 2 & 1\\3 & 2 & &\\6 & 0 & &\\\end{array}\\$

Equation (1) is the blue line in the graph below.

Equation (2) is the red line.

The two lines cross at the black dot

Your four points are labelled . The one that is closest to the intersection is (1, 4).

The approximate solution to the system of equations is (1, 4).

(05.06)A chocolate bar measures 40 mm wide, 80 mm long, and 5 and 1 over 2 mm high. Will’s Wrapping Company is making a wrapper

photoshop1234 [79]

Answer:

Will’s Wrapping Company needs 7,720 mm2 of paper to wrap the chocolate bar.

Step-by-step explanation:

we know that

The amount of paper needed to make the wrapper is equal to the surface area of the chocolate bar

The surface area of a rectangular prism (chocolate bar) is equal to

$SA=2B+PH$

where

B is the area of the base

P is the perimeter of the base

H is the height of he prism

In this problem we have

$L=80\ mm\\W=5\frac{1}{2}\ mm=5.5\ mm\\H=40\ mm$

<em>Find the area of the base</em>

$B=LW=(80)(5.5)=440\ mm^2$

<em>Find the perimeter of the base</em>

$P=2(L+W)=2(80+5.5)=171\ mm$

<em>Find the surface area</em>

$SA=2(440)+171(40)\\SA=7,720\ mm^2$
