What is the equation of the line that passes through (0, 3) and is perpendicular to y = = x + 5?
5

Answers

when you're doing a perpendicular line, you want the exact opposite of your original.

take, for example, a line with a slope of 2. the line perpendicular to it would have a slope of -2.

With a fraction, its pretty tricky. Let's say you have 2/7 as your slope. you want the EXACT opposite so

First, make it negative

Next, flip it around.

You get -7/2 as your slope perpendicular to your original line.

For the point passing through, if x equals 0, y equals your y intercept. your y value is 3 therefore b (y-intercept) equals 3.

For questions that are less simple than a plain y-intercept, (which you are guaranteed to encounter in the future) you simply input the y and x values into your y=mx+b equation.

Say we have an example here of a line with a slope of 4, and it passes through (5,-3). We have to find our B, or y-intercept, so we input the values.

-3=4(5)+b

Now, simplify

-3=20+b

-23=b

Your example equation is now y=4x-23

A TV has an original price of $499. Find the new price given a 10% increase.

Answers

The new price given is $648.7
Have a great day/night

Answer: $548.9

Step-by-step explanation:

To find the next price you have to find 10% of the original price then add it. You can find the increase by dividing 499 by 10 to get 10%.

499 divided by 10 = 49.9

Now add the increase to the original price for your answer!

499 + 49.9 = $548.9

Explain how to compare decimals. Use the numbers 6.75 and 6.732 to help you explain this process.

tysm I am struggling

Answers

Answer:

6.75>6.732

Step-by-step explanation:

We are given that

6.75 and 6.732

We have to compare two given decimal numbers.

First we convert like decimal number

In 6.75 there are two digits after decimal point.

In 6.732 , there are three digits after decimal point

Therefore, we put zero in 6.75 to convert like decimal number

Now, we get

6.750

Unit place of both decimal numbers are same and tenth place of both decimal number are same.

Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3

5 >3

Therefore, 6.750 is greater than 6.732

6.75>6.732

to compare these decimals, we first have to turn 6.75 into 6.750, so it has the same place value as 6.732. adding a 0 to the right side of the last digit in the decimal does not change its value. now, we compare them. 6=6, 7=7, 5≠3. since 5 is greater than 3, we know 6.75 is greater than 6.732. this can be written as 6.75>6.732.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that 0.9 is the result of finding the product of 2 and 3/4 minus a number.

The unknown number will be calculated as,

( 2 x 3) / 4 - N = 0.9

N = (3 / 2) - ( 9/10)

N = ( 15 - 9 ) / 10

N = 6 / 10

N = 3 / 5

Therefore, the unknown number will be equal to 3 / 5. The correct option is C.

The correct options are given below,

A) 3/40

B) 3/5

C) 33/40

D) 1 1/5

write 5.437 in expanded form

Answers

5+0.4+0.03+0.007 is the answer

The expanded form of the given decimal number is 5+0.4+0.03+0.007.

What is expanded from of a decimal number?

Unlike whole numbers, decimal numbers can also be written in the expanded form. For writing the decimals in expanded form, we multiply each of the decimal digits with increasing exponent values of (1/10).

The given decimal is 5.437

Now, the expanded form is

5+4/10+3/100+7/1000

= 5+0.4+0.03+0.007

Therefore, the expanded form of the decimal 5.437 is 5+0.4+0.03+0.007.

What fraction of the expected amount of power did Solaire's solar panels generate?

Answers

Answer:

I think the answer would be 11/10

Step-by-step explanation:

when simplifying a percent into a fraction you always make the denominator 100, since the percent is 110, the numerator is 110, so 110/100. From there you can take off the 0s from the ends of both and boom, 11/10, hope this makes sense!

11/10 or 1 1/10

110%/100% is equal to 11/10, or 1 1/10
