12 eggs for $1.12
3 eggs for $?
As you can see, to get from 12 eggs to 3 eggs, you divide by 4, so do the same with $1.12 to get $0.28
The cost of 3 eggs is $0.28

Does anyone have the answers for the rest of this or know the answers ?

irga5000 [103]

Answer:

a) $4x^4-4x^3-16x^2+16x$

b) $4x^4-4x^3-16x^2+16x$

5. Yes

Step-by-step explanation:

The distributive property is:

$(a+b)(c+d)=ac+ad+bc+bd$

It can be extended to a lot of terms as well.

We will use this to multiply both of the probelms shown.

4 a)

$(4x^2-4x)(x^2-4)=(4x^2)(x^2)-(4)(4x^2)-(4x)(x^2)+(4x)(4)=4x^4-16x^2-4x^3+16x=4x^4-4x^3-16x^2+16x$

The answer is $4x^4-4x^3-16x^2+16x$

4 b)

$(x^2+x-2)(4x^2-8x)=(x^2)(4x^2)-(8x)(x^2)+(x)(4x^2)-(8x)(x)-(2)(4x^2)+(2)(8x)=4x^4-8x^3+4x^3-8x^2-8x^2+16x=4x^4-4x^3-16x^2+16x$

The answer is $4x^4-4x^3-16x^2+16x$

5. Yes

How do you write y+1=4/5(x-3) in standard form?

Rudik [331]

Answer:

The standard form of the given expression is $- (\frac{4}{5})x + y + (\frac{17}{5}) = 0$

Step-by-step explanation:

Here, the given expression is $y + 1 = \frac{4}{5} (x-3)$

Now, the Standard Form of the equation is ax + by + c = 0

Solving this, we get:

$y + 1 = \frac{4}{5} (x-3) \implies y + 1 = (\frac{4}{5})x - \frac{12}{5}$

⇒ $y + 1 - (\frac{4}{5})x + (\frac{12}{5}) = 0$

or, $y - (\frac{4}{5})x + (\frac{12}{5} + 1 )= 0 \implies y - (\frac{4}{5})x + (\frac{12+ 5}{5}) = 0$

⇒ $y - (\frac{4}{5})x + (\frac{17}{5}) = 0$

Hence, the standard form of the given expression is $- (\frac{4}{5})x + y + (\frac{17}{5}) = 0$
