Find the slope between the following points: (6,-2) and (-18,4)

Answers

Answer:

[tex]-\frac{1}{4}[/tex]

Step-by-step explanation:

1. Use the slope formula:

[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

2. Using the x and y values from both points (it doesn't matter which order you choose the points in as long as you keep their numbering consistent, i.e. point 1 = [tex](x_1, y_1)[/tex] and point 2 = [tex](x_2, y_2)[/tex]) plug into the formula.

[tex]slope=\frac{4-(-2)}{-18-6}[/tex]

3. Simplify the fraction.

[tex]slope=\frac{6}{-24} =-\frac{1}{4}[/tex]

A carpet measures 7 meters 3 decimeters in length and 4 meters 2 decimeters in width. What is its area in square meters?

Answers

Answer:

C

Step-by-step explanation:

change decimetres into metres

length - 7.3m

Width - 4.2m

to find an area, do length times width

7.3 x 4.2 = 30.66 square metres

I hope this helped :)

Answer:

C. 30.66 square meters

Step-by-step explanation:

The equation for area is A = L × W

L = length

W = width

Because a demimeter is 1 tenth of a meter your new measurements are 7.3 and 4.2.

multiply the measurements to find the area of 30.66² meters

Answer:

4 2/15

Step-by-step explanation:

Convert both fractions to have the same denominator. Find the LCM of 3 and 5 and multiply by what you need to get there. 1x5=5, 3x5=15, so 1/3 becomes 5/15, and 1x3=3, 5x3=15, so 1/5 becomes 3/15. Finally, do normal subtraction, to get 4 2/15.

Write the subtraction expression as an equivalent addition expression and then evaluate it.

Rudolph will spend $150 on tickets to the Reindeer Games. Reserved seat tickets cost $25 and general admission
tickets cost $10. Write an equation that describes the number of tickets Rudolph can buy_How many tickets can
Rudolph buy if he buys only reserved seat tickets? Only general admission tickets?

Answers

The equation that describes the number of tickets Rudolph can buy will be 25r + 10g = 150.

Let the reserved tickets be represented by r.Let the general admission be represented by g.

Therefore, the equation will be 25r + 10g = 150.

The number of tickets that Rudolph can buy if he buys only reserved seat tickets will be:

= $150 / $25 = 6

The number of tickets that Rudolph can buy if he buys only general admission tickets will be:

= $150 / $10 = 15

Identify whether the following expression is a polynomial. If it is, identify the type according to the number of terms.
6x^2 + x + 1

Answers

Answer:

The expression is a polynomial.

Trinomial (according to the number of terms)

Step-by-step explanation:

Given the algebraic expression, 6x² + x + 1:

A term comprises of a product of numerical coefficient and one of more variables raised to powers.  Like terms have the same variables and exponents.

While a polynomial is a term (or finite sum of terms), comprising of variables with positive or zero integer exponents. Strictly defined, the terms within a polynomial expression cannot include variables as a denominator.  

A monomial is a single-termed polynomial.

A binomial is a polynomial with two terms.

A trinomial is a polynomial that has exactly three terms.

With these given definitions, we can infer that the given polynomial expression, 6x² + x + 1,  is a trinomial, given that it has three terms:

6x² is the leading term with the highest degree or exponent. Specifically, the name of this term is quadratic, given its exponent of 2. x is a linear term, given its exponent of 1. 1 is a constant term.

Therefore, the given expression is a polynomial containing three terms, making it a trinomial.
