d. -x + y = 8

Step-by-step explanation:

First find the rate of change [slope]:

-y₁ + y₂\-x₁ + x₂ = m

[tex]\frac{-7 + 10}{1 + 2} = \frac{3}{3} = 1[/tex]

Then, we can go ahead and use the Slope-Intercept Formula instead of the Point-Slope Formula because you get it done swifter. It does not matter which ordered pair you choose:

10 = 1[2] + b

2

8 = b

y = x + 8 >> Line in Slope-Intercept Form

Since the exercise wants the equation in Standard Form:

y = x + 8

-x -x

________

-x + y = 8 >> Line in Standard Form

__________________________________________________________

7 = 1[-1] + b

-1

8 = b

y = x + 8 >> Line in Slope-Intercept Form

y = x + 8

-x -x

________

-x + y = 8 >> Line in Standard Form

** You see? I told you it did not matter which ordered pair you chose because you will always get the exact same result, plus the fact that I told you it was alot swifter than the Point-Slope Formula.

* Tip: Use the Point-Slope Formula when it tells you to, otherwise keep using the Slope-Intercept Formula. That way, you get your work done in a jip!

Answer:

28°

Step-by-step explanation:

I had made a mistake and somehow got 38° but that is incorrect.

what you do is 1st subtract 180°-104° which equals 76

Then divide it by 0.5 (which means one-half) your answer should be 152.

After, subtract 152 from 180. Thus concluding the answer is 28°.

I hope no one makes the mistake I did. I forgot how I did it but the steps listed above are the correct steps. Have an amazing day brainly users.

Jenny swam more laps.

Step-by-step explanation:

Lets take this step by step. If Edith swam fewer laps than Shira but more than Gemma, then G < E < S. If Jenny swam more than Shira, then that means Gemma swam the fewest, then Edith, then Shira, and finally Jenny who swam the most laps.

Answer:

Jenny

Step-by-step explanation:

The reason why it's Jenny is because if Edith did not swim more laps that Shira but more laps than Gemma, that means Edith is second to last. Gemma is last because she did not swim more laps than anyone. Jenny would have swam the most laps out of the four girls.

Final answer:

Explanation of solving an arithmetic expression with exponents, division, addition, and subtraction following the order of operations.

Explanation:

To solve the expression 82 + 3 ×(36 / 6) - 2, follow the order of operations (PEMDAS):

Calculate the exponential term: 82 = 64

Divide 36 by 6: 36 / 6 = 6

Multiply 3 by the result of the division: 3 ×6 = 18

Substitute the values back into the original expression: 64 + 18 - 2

Answer:

40

Step-by-step explanation:

2/8 = 10/40

3/5 = 24/40

Final answer:

The least common denominator (LCD) of the fractions 2/8 and 3/5 is found by prime factorizing each denominator and then multiplying each fraction by the missing factors from the other denominator to get a common denominator, which in this case is 40.

Explanation:

To find the least common denominator (LCD) of the fractions 2/8 and 3/5, you would follow certain steps. First, since the denominators are not the same, you need to prime factorize each denominator. For 8, the prime factorization is 2 x 2 x 2, and for 5, it is simply 5 because it is already a prime number. To find the LCD, multiply each fraction by a fraction that is equal to "1", consisting of the missing factors from each denominator. In this case, we will multiply 2/8 by 5/5 and 3/5 by 8/8 to make the denominators the same.

The next step is to multiply the numerators and denominators accordingly. This gives us new fractions: 10/40 (from 2/8) and 24/40 (from 3/5), with a common denominator of 40. Hence, 40 is the LCD of 2/8 and 3/5.

If you were adding or subtracting these fractions, you would then be able to combine the numerators over the LCD. However, for this problem, we are only finding the LCD, so our work is complete.

Answer:

4 pieces of chair rail are needed

Step-by-step explanation:

Step 1: Calculate the perimeter of the room

Perimeter of rectangle = 2L + 2B

Length = 18

Breadth = 14

Perimeter of room = 2(18) + 2(14)

Perimeter of room = 64 feet

Step 2: Calculate the pieces of chair rail needed

Perimeter of room = 64 feet

Length of each chair rail = 16 feet

Total chair rails needed = Perimeter of room/length of each chair rail

Total chair rails needed = 64/16

Total chair rails needed = 4

Therefore, Mr. Herzog needs 4 pieces of chair rails.

Answer:

y = 2x - 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{1}{2}[/tex] x - 5 ← is in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2, thus

y = 2x + c ← is the partial equation of the line

To find c substitute (1, - 4) into the partial equation

- 4 = 2 + c ⇒ c = - 4 - 2 = - 6

y = 2x - 6 ← equation of line

i think its -4

aka B

Step-by-step explanation:

Answer:

(B) -4

Step-by-step explanation:

Say the other number is a. The sum is a+P, which also equals 24.

Write it as, a+P=24.

Now subtract P from both sides.

you get, a = 24-P

So, the other number in terms of P is 24 - P

To express the other number in terms of P when the sum of the two numbers is 24, subtract P from 24: Q = 24 - P.

In Mathematics, when you have a sum of two numbers, and you know the value of one number, you can find the other number by subtracting the known number from the total sum.

This is known as solving for a variable.

In this specific question where two numbers have a sum of 24, and if one number is P, the other number can be expressed in terms of P as 24 - P.

It is a simple equation derived from the basic formula: Sum = Number1 + Number2

Final answer:

The problem involves creating two linear equations based on the given information and then solving them simultaneously to find that there are six 6-volt batteries and four 12-volt batteries among the ten.

Explanation:

Solving the Battery Voltage Problem

To solve the problem, we will use a system of linear equations. Let's denote the number of 6-volt batteries as x and the number of 12-volt batteries as y. Since there are ten batteries in total, we can write the following equation:

1. x + y = 10 (Equation for the total number of batteries)

The sum of voltages of all batteries is given to be 84 volts. Each 6-volt battery contributes 6 volts and each 12-volt battery contributes 12 volts to the total voltage. We can write the second equation for the sum of the voltages:

2. 6x + 12y = 84 (Equation for the total voltage from the batteries)

To find the values of x and y, we can simplify the second equation:

3. Divide the second equation by 6:

x + 2y = 14

Now we can subtract the first equation from this new equation to find the value of y:

4. (x + 2y) - (x + y) = 14 - 10

5. y = 4

Now that we know there are four 12-volt batteries, we can use the first equation to find the number of 6-volt batteries:

6. x = 10 - y

7. x = 10 - 4

8. x = 6

Therefore, the group consists of six 6-volt batteries and four 12-volt batteries.
