Snezhnost [94]

Answer: y = 3+b

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

y = x + b

Where:

y = total number of ceramic cats

x = actual number of ceramic cats

b=new ceramic cats bought

Replacing with the value given:

y = 3+b

Where y is the dependant variable and b the independent variable.

Feel free to ask for more if needed or if you did not understand something.

How does this polynomial identity work on numerical relationships?<br> (y + x) (ax + b)
Serggg [28]

Let us take 'a' in the place of 'y' so the equation becomes

(y+x) (ax+b)

Step-by-step explanation:

<u>Step 1:</u>

(a + x) (ax + b)

<u>Step 2: Proof</u>

Checking polynomial identity.

(ax+b )(x+a) = FOIL

(ax+b)(x+a)

ax^2+a^2x is the First Term in the FOIL

ax^2 + a^2x + bx + ab

(ax+b)(x+a)+bx+ab is the Second Term in the FOIL

Add both expressions together from First and Second Term  

= ax^2 + a^2x + bx + ab

<u>Step 3: Proof </u>

(ax+b)(x+a) = ax^2 + a^2x + bx + ab

Identity is Found .

Trying with numbers now

(ax+b)(x+a) = ax^2 + a^2x + bx + ab

((2*5)+8)(5+2) =(2*5^2)+(2^2*5)+(8*5)+(2*8)

((10)+8)(7) =(2*25)+(4*5)+(40)+(16)

(18)(7) =(50)+(20)+(56)

126 =126

Sheryl's boss at always 21 pays a 5% commission on all sales. If Sheryl sells $140 worth of clothes, how much commission does sh
mariarad [96]

Answer:

She earns $7.

Step-by-step explanation:

5 percent of 140 is 7. You can think of this as taking ten percent of 140.0 by moving the decimal point one place to the left, 14, and then since 10 divided by 2 is 5, divide that by 2 and you get 7.
