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

write 5.437 in expanded form
Answers
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.

Find

and then find the slope of the tangent line at
(
2
,
225
)
. Round the slope and y-intercept to 3 decimal place.
Answers
To find the slope, you plug in 2 for y’ as it is the x-value of the point.
y’ = 2((2)^2+2(2)+7)(2(2)+2) = 180
Plug in the point and the slope in the point-slope formula
y - y1 = m(x - x1)
y - 225 = 180(x - 2)
Solve for y
y = 180x - 360 + 225
y = 180x - 135

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

ex:
The mixed number is [tex]-14 \frac{4}{7}[/tex]
What are Mixed Numbers?
A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
Given data ,
[tex]\frac{p}{1\frac{3}{7} } = -10.2[/tex]
To solve for p ,
Multiply by [tex]1\frac{3}{7}[/tex] on both sides we get ,
p = [tex]-10.2[/tex] × [tex]1\frac{3}{7}[/tex]
Now , [tex]1\frac{3}{7}[/tex] can be written as the improper fraction form as [tex]\frac{10}{7}[/tex]
So ,
p = [tex]-10.2[/tex] × [tex]\frac{10}{7}[/tex]
p = [tex]\frac{-102}{7}[/tex]
Now , the improper fraction [tex]\frac{-102}{7}[/tex] can be represented by the mixed number as [tex]-14 \frac{4}{7}[/tex]
Hence , The mixed number is [tex]-14 \frac{4}{7}[/tex]

Let x be the number of rolls sold by Sean.
We are given that Evan has sold 7 more that one-half the number of rolls that Sean sold.
Evan has sold 1/2x + 7 rolls.
Therefore, we have:
x + (0.5x + 7) = 121
1.5x = 121 - 7

Step-by-step explanation:
We are given that

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
