How do you write x+y=9 in y=mx+b?

Answer:They are 600 feet apart from each other

Step-by-step explanation:

Answer:

600

Step-by-step explanation:

the 200 since its below the surface it would become negitive and 400 - -200 would turn into 400 + 200 and that would be 600 :)

Answer:

31.42 ft

Step-by-step explanation:

C = 2pi times r

d = 2 r

C = pi times 10 = 31.42 ft

Answer:

3x + 4.5x + 1 = 28

3.6 seconds

Step-by-step explanation:

Initial distance apart = 1 foot

Student A:

Walk rate = 3 ft per second

Student B:

1.5*3 = 4.5 ft per second

How long it will take to be a total of 28 feets apart

Distance = speed * time

Let time = x in seconds

Student A distance = 3x

Stident B distance = 4.5x

Initial distance = 1 foot

3x + 4.5x + 1 = 28

7.5x = 28 - 1

7.5x = 27

x = 27/ 7.5

x = 3.6 seconds

It is. 4 ( 6x- 5) Hope this helped

whole number between 4 and 8 is 5,6 and7

and between 12 and 16 is 13,14 and 15

Answer:

a) 5,6,7

b) 13,14,15

Step-by-step explanation:

Answer: -3, -2.4, -2 1/4, -1.5, -1 1/8

Step-by-step explanation:

The list that orders the numbers from least to greatest is; -3, -2.4, -2 1/4, -1.5, -1 1/8

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines. Number lines might be alternatively left empty or blank. A number ladder is a vertical number line.

We have been given number line going from negative 4 to positive 4.

Negative 2.4, negative 1.5, negative 2 and one-fourth, negative 3, negative 1 and one-eighth

For this we need to remember the number line, we have that that:

-3 <-2.4 < -2 < 1/4 <-1.5 < -1 <  -1 1/8< 0

We go from the big negative numbers, to the small negative numbers, the zero, the small positive numbers, the big positive numbers.

Therefore, the numbers from least to greast the correct options are:

-3, -2.4, -2 1/4, -1.5, -1 1/8

Answer:

the 2nd equation

Step-by-step explanation:

use formula for slope

y2-y1/x2-x1 =m

7-1/2-0=6/2

=3

y=3x+1

y-1=3x

Answer:

y – 1 = 3x

number 2

Step-by-step explanation:

Answer:

Step-by-step explanation:

Firstly we know that in geometry parallel lines have the same slope

[tex]m_1=m_2[/tex]

and ,

perpendicular lines have the slope denoted by the formula  

[tex]m_1m_2=-1[/tex].

Secondly ,

x = 1 is a line that is parallel to the y-axis, and any line parallel to the y-axis has undefined slope.

and the slope of a line perpendicular to x = 1 would be parallel to the x-axis and any line parallel to the x-axis has the slope of zero.

Slope for parallel line is undefined and slope for perpendicular line is zero.

The slope or gradient of a line is a number that describes both the direction and the steepness of the line.

Given:

graph equation, x=1

The slope for parallel line is

m1 = m2

and, the slope for perpendicular lines is

m1 * m2 =-1

As, x = 1 is a line is parallel to the y-axis, and line parallel to the y-axis has undefined slope.

Also, the slope of a line perpendicular to x = 1 would be parallel to the x-axis.

So, line will have the slope zero.

Answer:

The domain of [tex]f(x)[/tex] is [tex]Dom \{f(x)\} = \mathbb{R}-\{1\}[/tex].

Step-by-step explanation:

Let [tex]f(5\cdot x ) = \frac{x-5}{5\cdot x-1}[/tex], which is rearranged by algebraic means:

1) [tex]f(5\cdot x ) = \frac{x-5}{5\cdot x-1}[/tex]  Given

2) [tex]f(5\cdot x) = \frac{x\cdot 1 - 5}{5\cdot x -1}[/tex] Modulative property

3) [tex]f(5\cdot x) = \frac{5^{-1}\cdot (5\cdot x)-5}{5\cdot x -1}[/tex] Existence of multiplicative inverse/Associative and commutative properties.

4) [tex]f(x) = \frac{5^{-1}\cdot x - 5}{x-1}[/tex] Composition of functions.

5) [tex]f(x) = \frac{(5^{-1}\cdot x-5)\cdot (5\cdot 5^{-1})}{x-1}[/tex] Existence of multiplicative inverse/Associative property.

6) [tex]f(x) = \frac{(x-25)\cdot 5^{-1}}{x-1}[/tex]  Commutative, associative and distributive properties/[tex]a\cdot (-b) =-a\cdot b[/tex]/Definition of subtraction

7) [tex]f(x) = (x-25)\cdot [5^{-1}\cdot (x-1)^{-1}][/tex] Definition of division/Associative property

8) [tex]f(x) = (x-25)\cdot (5\cdot x -5)^{-1}[/tex]  [tex]a^{c}\cdot b^{c} = (a\cdot b)^{c}[/tex]/Distributive property/[tex]a\cdot (-b) =-a\cdot b[/tex]/Definition of subtraction

9) [tex]f(x) = \frac{x-25}{5\cdot x - 5}[/tex] Definition of division/Result

The domain of a polynomial-based rational function consists in all values of the real set except values where denominator equals zero. The value of [tex]x[/tex] such that rational function becomes undefined is:

1) [tex]5\cdot x - 5 = 0[/tex]  Given

2) [tex]5\cdot (x-1) = 0[/tex] Distributive property

3) [tex][5\cdot (x-1)]\cdot 5^{-1} = 0\cdot 5^{-1}[/tex] Compatibility with multiplication

4) [tex](x-1)\cdot (5\cdot 5^{-1}) = 0[/tex] Commutative and associative properties/[tex]a\cdot 0 = 0[/tex]

5) [tex]x-1 = 0[/tex] Existence of multiplicative inverse/Modulative property

6) [tex]x+[1+(-1)] = 1+0[/tex] Compatibility with addition/Commutative and associative properties

7) [tex]x = 1[/tex] Existence of additive inverse/Modulative property/Result

Hence, the domain of [tex]f(x)[/tex] is [tex]Dom \{f(x)\} = \mathbb{R}-\{1\}[/tex].

Answer:

[tex]A_2 = 7.5cm^2[/tex]

Step-by-step explanation:

The attachment completes the question

Given

[tex]Area = 15cm^2[/tex]

Required

Area of green triangle

[tex]The\ area\ of\ a\ parallelogram\[/tex] is calculated as

[tex]A_1 = b * h[/tex]

and

[tex]A_1 = 15cm^2[/tex]

Where:

[tex]b=base[/tex]

[tex]h = height[/tex]

Because the triangle shares exact base and height with the parallelogram, the area of a triangle is calculated as

[tex]A_2 = \frac{1}{2} * b * h[/tex]

Recall that:

[tex]A_1 = b * h[/tex]

So, we have:

[tex]A_2 = \frac{1}{2} *A_1[/tex]

Substitute [tex]15cm^2[/tex] for [tex]A_1[/tex]

[tex]A_2 = \frac{1}{2} * 15cm^2[/tex]

[tex]A_2 = \frac{ 15cm^2}{2}[/tex]

[tex]A_2 = 7.5cm^2[/tex]

The area of the triangle is 7.5cm^2

Answer:

Cos 2u = 7/25

Step-by-step explanation:

Here, we want to find the value of cos2u

Using formula, we can rewrite cos 2

Mathematically;

cos 2u = 2cos^2 U - 1

Thus, we have that

cos 2u = 2(4/5)^2 - 1

cos 2u = 2(16/25) - 1

cos 2u = 32/25 - 1

cos 2u = (32-25)/25 = 7/25
