**Answer 1**

**Answer: 68x + 36y**

**Step-by-step explanation:**

Combine Like Terms:

= 19x + 4y + 49x + 32y

= (19x + 49x) + (4y + 32y)

= 68x + 36y

Hope this helped you!

**Answer 2**

**Answer:**

68x + 36y

**Step-by-step explanation:**

You can compeletely get rid of the parenthesis because it is addition through and thorough.

You have 19x + 4y + 49x + 32y

You can combine like terms to get

19x +49x which is 68x

and

4y + 32y which is 36y

You now have 68 + 36y which cannot be simplified anymore because the variables are different.

Hope this helps!

Explain the difference between parallel and perpendicular lines in terms of their slopes. What form of equation of a line is easiest to determine slope?

### Answers

**Answer:**

Parallel lines have the same slope, while perpendicular lines have completely opposite slopes. So a line has a slope of 2, a parallel line would have a slope of 2, and a perpendicular line would have a slope of -1/2. The easiest form to identify the slope is standard form because it shows the slope within the equation with out having to solve the equation or convert it into another form.

Which function has a domain of all real numbers?

A. y=-x½+5 B. y=(2x)⅓-7 C. y=(x+2)¼ D. y=-2(3x)⅙?

### Answers

**Answer:**

**B.**

**Step-by-step explanation:**

B. Because the others have exponents whose denominators are even so the results of , for example x^1/2, if x is negative is not defined.

For example:

For A, when x is -4, (-4)^1/2 is not real.

For B, when x = -4, (2*-4)^ 1/3 = -8^(1/3) = = -2.

hurryyy!! Otero translated the phrase "three less than a number" into the expression 3 - X. Which best describes the accuracy of

Otero's expression?

It is accurate. The phrase can be translated as "three" = 3, "less than" = subtraction, and "a number" = X, SO 3- X is

the correct expression.

It is inaccurate. Three is being subtracted from a number, so X-3 is what he should have written.

It is inaccurate. Three is being compared to a number, so 3 It is inaccurate. Three is being added to a number, so 3+ x is what he should have written.

### Answers

**Answer:**

A. It is accurate. The phrase can be translated as “three” = 3, “less than” = subtraction, and “a number” = x, so 3-x is the correct expression.

### Answers

Because they are congruent sides

**Answer:**

AB = DC Given

AC = DB Given

BC = BC Reflexive property

△ACB = △DBC SSS

m∠DBC = m∠ACB CPCTC

**Step-by-step explanation:**

Reflexive property basically means that something is congruent to itself

SSS means that if all 3 sides of 2 triangles are congruent, the triangles are congruent

CPCTC means C.orresponding P.arts of C.ongruent T.riangles are C.ongruent

meaning because the triangles are congruent, all the corresponding sides and angles are also congruent

### Answers

The other person provided a great answer but i do it a little different....

[tex]\left[\begin{array}{ccc}A^2=C^2-B^2\\A^2=10^2-6^2\\A^2=100-36\\A^2=64\\\sqrt{64}=8 \end{array}\right][/tex]

All i did was use the formula A^2=C^2-B^2. I Plugged in the numbers to the formula and got A^2=10^2-6^2. Next, I found what 10^2 equals by doing 10*10 which equals 100. Then, i found out what 6^2 equals by doing 6*6 which equals 36. Next, what i did was subtracted 100 from 36 and got 64. Finally i found the square root of the number 64 which equal 8 since 8x8=64.

What is Pythagoras theorem?

The Pythagorean theorem or Pythagoras' theorem is a fundamental relation in** Euclidean geometry** between the three sides of a right triangle. Mathematically, it can be written as -

**(hypotenuse)² = (base)² + (perpendicular)²**

Given is a** right angle** triangle.

Using the **Pythagoras theorem**, we can write -

(hypotenuse)² = (base)² + (perpendicular)²

(10)² = (base)² + (6)²

(base)² = (10)² - (6)²

(base)² = (10 - 6)(10 + 6)

(base)² = 4 x 16

(base)² = 64 inches

(base) = 8 inches

**x = 8 inches**

Therefore, the measure of the unknown variable {x] is **8 inches**.

### Answers

Y = -x is the answer.

The cost of a gym membership is $25 per month. There is an initial fee of $40

### Answers

**Answer:**

y = 25x + 40

**Step-by-step explanation:**

Using the formula, y = mx + b we can find out what this equation would be.

m = the rate of change/slope

b = the y- intercept

25 per month is telling us that this is the rate of change.

Since the $40 is only paid once, you can tell that this is the y intercept.

The equation will look like:

y = 25x + 40

On a graph it would look like:

Let the total cost of a gym membership be y, with the number of months as x.

The total cost would be 40 dollars, the initial fee, plus 25 times the number of months (x).

**y = 40 + 25x**
