Write the expression add thirty-eight and fifty-two, then divide by four and half.

HELP ME RIGHT NOW PLEASE.

Answer: -6

Step-by-step explanation:

$-2g+3>-5(g+1)$

First of all, solve the inequality.

Distribute -5 in the parentheses.

$-2g+3>-5g-5$

Add 5g and subtract 3 from both sides.

$-2g+5g>-5-3$

Combine like terms

$3g>-8$

Divide by 3.

$g>-\frac{8}{3}$

This means that any input (g) has to be greater than $-\frac{8}{3}$ . If you do not know what is $-\frac{8}{3}$ , divide 8 by 3. That is equal to approximately $-2.67$ . Therefore, g has to be greater than -2.67, this will leave -6 out of the choices.

The Carter family just left the local pet store with Rex, their new family dog. The pet store owner told the Carter family that

Korolek [52]

Answer:

A.)

In 2 months, Rex is 6 pounds and in 8 months he's 9lbs (from 2 to 8 is 6 months). So I inferred that to get to 9lbs from 6lbs is to go 0.5 pounds more each month.

B.)

2 = 6

3 = 6.5

4 = 7

5 = 7.5

6 = 8

7 = 8.5

8 = 9

C.) I don't think I can create a linear model here. So I don't think its nessesary.

D.)

If Rex were to grow over the expected 6 months, it would be 45.

Another annoying question. Please help me.

Volgvan

Answer:

1.15b

b + 0.15b

b + (15/100)b

Step-by-step explanation:

Since the question asks for the equation that represents the pay plus the tip, which is 15% of the bill, your only answer choices are:

1.15b

b + 0.15b

b + (15/100)b

Why?

Ok, b is the bill in dollars. If I have to pay 15 dollars and I tip 15% of that, then I should be paying more than 15 dollars. In this example I gave, b is 15 dollars.

15% of b can be expressed in two ways (there's more but for now) : 0.15b or (15/100)b

15/100 is a fraction, which in decimal form is 0.15, so they are both exactly the same.

So, paying 15 dollars + 15% of the 15 will be 17.25.

Now, let's plug 15 dollars from our example in the answer choices to verify they are correct

b = 15

1.15b == 17.25

1.15(15) == 17.25

17.25 == 17.25 Correct

b + 0.15b == 17.25

15 + 0.15(15) == 17.25

15 + 2.25 == 17.25

17.25 == 17.25

There is another way of doing the above.

b + 0.15b == 17.25 # Combine like terms.

1.15b == 17.25

And then, b + (15/100)b is the same as b + 0.15b which is the same as 1.15b

Now, let's see what happens if we did a wrong one.

b + 0.15 <-- This one we expect b which is 15 and adding .15 cents no matter the cost

15 + 0.15 == 17.25

15.15 ≠ 17.25

1.015b <-- 0.015 in percent form is 1.5% not 15%.

1.015(15) == 17.25

15.225 ≠ 17.25

15b <-- We are multiplying b by 15. You better know your math otherwise you might pay 15x what you were supposed to pay!

15(15) == 17.25

225 ≠ 17.25

If you want to test out your equations, replace the variable; whether it is x, y, z, a, b, c - they are placeholders. Replace the placeholder with real values or equations (you will experience later).

You are going to design an advertisement for a new polynomial identity that you are going to invent. Your goal for this activity

Zigmanuir [339]

Answer:(ax+b) (x+a)

Use FOIL on second term

Assignment details:

It's time to show off your creativity and marketing skills!

You are going to design an advertisement for a new polynomial identity that you are going to invent. Your goal for this activity is to demonstrate the proof of your polynomial identity through an algebraic proof and a numerical proof in an engaging way! Make it so the whole world wants to purchase your polynomial identity and can't imagine living without it!

You may do this by making a flier, a newspaper or magazine advertisement, making an infomercial video or audio recording, or designing a visual presentation for investors through a flowchart or PowerPoint.

You must:

• Label and display your new polynomial identity

• Prove that it is true through an algebraic proof, identifying each step

• Demonstrate that your polynomial identity works on numerical relationships

WARNING! No identities used in the lesson may be submitted. Create your own. See what happens when different binomials or trinomials are combined. Below is a list of some sample factors you may use to help develop your own identity.

• (x – y)

• (x + y)

• (y + x)

• (y – x)

• (x + a)

• (y + b)

• (x2 + 2xy + y2)

• (x2 – 2xy + y2)

• (ax + b)

• (cy + d)

The numerical proof is correct! This identity had been proven right in front of your eyes

Algebraic Proof

Amber Carter

Polynomial Identities

So, you want even more proof? Well then lets just substitute in values for a, b, and x. Lets make a=2, b=4, and x=6.

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

(ax+b) (x+a)

+bx +ab

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

This identity is effective and easy to use!

The New Identity

To solve this you have to use the distributive property, more specifically FOIL

Use FOIL on first term

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

((2*6)+4) (6+2) = (2^2*6) +(4^2*6) +(2*4)

128 = 128

(16) (8) = (24)+(96)+(8)

Module 4.08

Numerical Proof

I hope this was adequate proof to convince you to love my new polynomial proof!

ax^2+a^2x

The following is an advertisement for the newest polynomial identity. If you like the way your life is now and do not wish to add this new identity to your knowledge, then please do not go any further. This identity is not for those who are non-accepting of new and improved ideas.
