Answers

Answer 1
Answer:

Step-by-step explanation: First equation: 3.4.1 3y + 7 = 4y

Subtract 3y from both sides: 3.4.1 (3y - 3y) + 7 - 3y = 4y - 3y

Simplify: 3.4.1 7 = 4y

Divide both sides by 3.4.1: 7 / 3.4.1 = 4 / 3.4.1 * y

Multiply both sides by y: 7y = 4 * 3.4.1y

Substitute 7y with LHS: 4 * 3.4.1y = 7 *  Second equation: 3.4.2 10 - 3y + 4 = 8 + 4v - y

Add 3y to both sides: 3.4.2 (10 - 3y + 4) + 3y = 8 + 4v - y + 3y

Simplify: 3.4.2 17 = 12 + 4v

Subtract 12 from both sides: 3.4.2 (17 - 12) + 12 = 4v

Divide both sides by 3.4.2: 4.2 * 5 = 4v

Multiply both sides by v: 4.2v = 4 *

What is the completely factored form of f(x) = 6x3 – 13x2 – 4x + 15?(x + 1)(6x2 – 19x + 15)
(x + 1)2(2x – 3)
(x + 1)(3x – 2)(5x – 3)
(x + 1)(2x – 3)(3x – 5)

Answers

We have to determine the complete factored form of the given polynomial

f(x)=6x^3-13x^2-4x+15.

Let x= -1 in the given polynomial.

So, f(-1)= 6(-1)^3-13(-1)^2-4(-1)+15 = -6-13+4+15 = 0

So, by factor theorem

(x+1) is a factor of the given polynomial.

So, dividing the given polynomial by (x+1), we get quotient as 6x^2-19x+15.

So, 6x^3-13x^2-4x+15 = (x+1)6x^2-19x+15.

= (x+1)(6x^2-10x-9x+15)

=(x+1)[ 2x(3x-5)-3(3x-5)]

= (x+1)(2x-3)(3x-5) is the completely factored form of the given polynomial.

CupCaking, a cupcake bakery, uses the equation below to determine the price of cupcakes, where y represents the total price in dollars and x represents the number of cupcakes purchased.Y=3/2x

Cake Me, another cupcake bakery, uses the table below to determine prices.
(x) (y)
2 3.50
3 5.25
4 7.00
6 10.50

Katie bought one cupcake from CupCaking and Sarah bought one cupcake from Cake Me.

Which of the following are true?
A) Katie is paying the smaller price of $1.50 per cupcake.
B)Sarah is paying the smaller price of $1.25 per cupcake.
C) Katie is paying $0.25 per cupcake more than Sarah.
D)Sarah is paying $0.25 per cupcake more than Katie.
E)They are paying the same price per cupcake.

You can pick more then one :)

Answers

A is true and D is true because 3 divided by 2 is 1.5 and x is 1 ( the number of cupcakes she is buying) so the total she is paying for is 1.50 while if you notice the pattern in cake me they are charging 1.75 per cupcake. (7.00 - 1.75 = 5.25)

Answer:

Katie is paying the smaller price of $1.50 per cupcake.

Sarah is paying $0.25 per cupcake more than Katie.

Have a good day.
