2x-1=20

2x=20/1

2x=20

x=20/2

x=10

2x+3y =20

2×10+3y=20

20+3y=20

3y=20-20

3y=0

3/0=y

y=0

Compute each quotient using the identities you discovered in this lesson.x^4-16/x-2

luda_lava [24]

Answer:

The quotient will be $(x^2+4)(x+2)$

Step-by-step explanation:

We have given the equation $\frac{x^4-16}{x-2}$

We have to find the quotient

From algebraic equation we know that $a^2-b^2=(a+b)(a-b)$

So $\frac{x^4-16}{x-2}=\frac{(x^2)^2-4^2}{x-2}=\frac{(x^2+4)(x^2-4)}{x-2}=\frac{(x^2+4)(x+2)(x-2)}{x-2}=(x^2+4)(x+2)$

So the quotient will be $(x^2+4)(x+2)$

What is the unit rate for Bill's boffo bagel?

Tema [17]

<u>Given</u>:

Given that the graph of Bill's Boffo Bagel.

We need to determine the unit rate for Bill's Boffo Bagel.

The unit rate can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Let us substitute any two coordinates that the line passes through the points in the graph.

Substituting the coordinates (2,7) and (4,14) in the above formula, we get;

$m=\frac{14-7}{4-2}$

Simplifying, we get;

$m=\frac{7}{2}$

$m=3.5$

Therefore, the unit rate for Bill's Boffo Bagel is $3.5.

Hence, the unit rate is $3.50 for 1 bagel.

Thus, Option b is the correct answer.
