Answers

Answer:

-2/1

Step-by-step explanation:

Rise over run. The line goes up 2 blocks, and over 1. It's a negative because The line is going downward.

Answer:

The slope is -2

Step-by-step explanation:

Let's find the slope between your two points.

(−4,3); (−3,1)

(x1, y1) = (−4, 3)

(x2, y2) = (−3, 1)

Use the slope formula:

m = y2 − y1 / x2−x1

= 1 − 3 / −3 − −4

= −2 / 1

= −2

Answer:

m = −2

B) 1/5
C) 2
D) 32
E) 512

Answers

B) 1/5.....................

Answer: D) 32

Step-by-step explanation:

To solve the expression (4 to the negative power of 1)(2 to the 3rd power divided by 4 to the negative power of 2), we can follow these steps:

Step 1: Simplify 4 to the negative power of 1

4 to the negative power of 1 can be written as 1/4 to the positive power of 1, so the expression becomes: (1/4)(2 to the 3rd power divided by 4 to the negative power of 2)

Step 2: Simplify the division of powers of 4

When dividing powers with the same base (in this case, 4), we can subtract the exponents. So, 4 to the negative power of 2 is the same as 1/4 to the power of 2, which equals 1/16. The expression now becomes: (1/4)(2 to the 3rd power divided by 1/16)

Step 3: Simplify 2 to the 3rd power 2 to the 3rd power is 2x2x2, which equals 8. The expression now becomes: (1/4)(8 divided by 1/16)

Step 4: Simplify the division

Dividing by a fraction is the same as multiplying by its reciprocal. So, we can rewrite the expression as: (1/4)(8 x 16)

Step 5: Multiply 8 x 16 equals 128, so the expression simplifies to: (1/4)(128)

Step 6: Simplify the final expression

Multiplying 1/4 by 128 gives us 32. Therefore, the final answer is: 32

The simplified addition expression with two terms for the perimeter of the polygon is 52 + 8x.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.

We are given the dimension of the polygon.

We need to find the perimeter of the polygon shown. so just add the dimensions then we get;

30-2x + 2x-4 + 18 + x+7 + 3x +4x+1

= 52 + 8x

This is the simplified addition expression with two terms.

Penny reads 12 pages in 1/4 of an hour. What is the unit rate of pages per hour, and what is the unit rate of hours per page? I know the unit rate of pages per hour is 48, but I am stuck on the unit rate of hours per page. I'm coming up with .020833. Please help. Thanks.

Answers

Your correct because 1/4 isn’t necessarily an hour it’s 15 minutes. So if yu divide that you would get .020833 yu would just have to round.

Penny can read 1 page in 1 minute and 14 seconds.

What is a unitary method?

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Penny reads 12 pages in 1/4 of an hour.

Now In (1/4)×4 hours, Penny can read (12×4) pages which is in 1 hour she can read 48 pages.

Now to obtain the unit rate of hours per page is we have to divide 1 hour by 48 pages which is (1/48) = 0.020833 hours or (0.020833×60) minutes = 1.24 minutes or 1 minute 14 seconds.
