Answer:

45/r

Step-by-step explanation:

You're just doing 45 divided by r.

Answer:

x-2y = 8

-2y = -x + 8

y = x/2 - 4

y intercept: (0, -4)

slope: 1/2

3x-2y = 12

-2y = -3x + 12

y = 3x/2 - 6

y intercept: (0, -6)

slope: 3/2

I assume I would graph with the following points (0,-4) and (4,0) for the second one I assumed I would graph the following points (0,-6) (6,0). I think I have confused the actual points in which I am to graph. Could you please tell me if I am graphing the correct points? I do not have the ISBN for this book becasue it is an online class. Thanks and have a great day!!

Admission for adults is 12 dollars. Admission for kids is eight dollars.One day 575 people entered the cave paying 5600 how many adults into the cave

Answer:

Ross initially owed 5625. the y intercept is 0,3500. Part of the answer.

There are x and y-intercepts that would be  5625 and 45 respectively for the given equation.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Ross borrows $5625 to buy a car. He pays back $125 each month which is given in the question.

The equation y = 5625 - 125x represents the amount Ross owes y after x months

⇒ y = 5625 - 125x

To determine the y-intercepts of the equation,

We have to substitute x = 0 in the equation

⇒ y = 5625 - 125(0)

⇒ y = 5625

To determine the x-intercepts of the equation,

We have to substitute y = 0 in the equation

⇒ 0 = 5625 - 125x

⇒ 125x = 5625

⇒ x = 45

Hence, there are x and y-intercepts that would be  5625 and 45 respectively for the given equation.

Answer:

If x represents the number of laptops sold and y represents the total weekly income, our equation would be y = 55x + 150

Answer:

Step-by-step explanation:

Every week, the given or set in stone amount of money she receives $150. So automatically, the first part of the equation is 150x, because x represents the number of weeks, and 150 is $150. So for instance, if she works for two weeks, she will earn $300. Anyway, she has an additional amount of money she gets, which is $55 for every laptop she sells. This isn't a set in stone amount of money. She might not always earn the extra $55, because she might not sell a laptop for a certain week. So, the final equation would be 150x+55. Hope this helped :)

Answer:

We have:

If:

Cos(θ) + Sin(θ) = √2*cos(θ)

We want to prove that:

Cos(θ) - Sin(θ) = √2*Sin(θ)

Well, let's start with the first relation:

Cos(θ) + Sin(θ) = √2*cos(θ)

Now we can subtract 2*Sin(θ) and we will get:

Cos(θ) + Sin(θ) - 2*Sin(θ) = √2*cos(θ) - 2*sin(θ)

Cos(θ) - Sin(θ) = √2*cos(θ) - 2*sin(θ)

Now, we also can rewrite the first equation as:

Cos(θ) + Sin(θ) = √2*cos(θ)

Cos(θ) - √2*cos(θ) = -  Sin(θ)

Cos(θ)*( 1 - √2) = -Sin(θ)

Cos(θ) = -Sin(θ)/( 1 - √2) = Sin(θ)/(- 1 + √2)

We can replace this in the right side of theequation:

Cos(θ) - Sin(θ) = √2*cos(θ) - 2*sin(θ)

Cos(θ) - Sin(θ) = √2* Sin(θ)/(- 1 + √2) - 2*sin(θ)

Cos(θ) - Sin(θ) = (√2/(- 1 + √2) - 2)*Sin(θ)

Now we have this:

√2/(- 1 + √2)) - 2 = a

if we multiply all by (-1  + √2) we get:

√2 - 2*(-1  + √2) = a*(-1  + √2)

√2  + 2 - 2*√2 =  a*(-1  + √2)

2 - √2 = a*(-1  + √2)

√2*(√2 - 1) = a*(-1  + √2)

√2*(√2 - 1)/(-1  + √2) = a

√2 = a

Then:

√2/(- 1 + √2)) - 2 = √2

If we replace this in the equation:

Cos(θ) - Sin(θ) = (√2/(- 1 + √2) - 2)*Sin(θ)

We get:

Cos(θ) - Sin(θ) = √2*Sin(θ)

Which is the thing we wanted to get.

Answer:

The third time = 11.64 seconds

Step-by-step explanation:

Let the average time be x

The average of a set of numbers is the sum of the numbers divided by the number of terms. In this case:

Average = (10.84 + 13.52 + x) ÷ 3 = 12.0

[tex]\frac{10.84\ + 13.52\ + x}{3}= 12.0\\\frac{24.36\ +\ x}{3} = 12.0\\cross-multiplying\\24.36\ +\ x = 3 \times 12.0\\24.36\ +\ x = 36\\x = 36 - 24.36\\x = 11.64\ seconds[/tex]

Answer:

Answer:

8 glasses

Step-by-step explanation:

You divide [tex]6.8/0.8[/tex]

This gives you 8.5 glasses

since 9 glasses is too much, at 7.2 liters. The maximum glasses possible is 8 assuming you're not filling a half of the glass which would be 8.5 glasses.

Answer:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points

Answer:

To the find slope in slope-intercept form (y=mx+b) you just find the m of the equation for example: y=4x+8 the 4 is the slope since it is replacing the m

To find the slope in two points (x1,y1) (x2,y2) follow this formula

y2-y1/x2-x1

For example: Find the slope of (4,9) and (9,19)

19-9/9-4 Which is 10/5 simplify: 2

The slope is 2

Step-by-step explanation:

Answer:

y - 1 = -8(x -9)

Step-by-step explanation:

Point-slope form is y - y1 = m(x - x1) given a point (x1, y1) on the line and slope m. Plug all the values in and this is the answer.

Step-by-step explanation:

The area of a cone is

[tex]\pi \times r {}^{2} + \pi \times r \times \sqrt{ {r }^{2} + {h}^{2} } [/tex]

The volume of the conical paper cup will be option (D) 24π

The steps are as follow:

r = base radius = 3 cm

h = height of cone = 8 cm

V = volume of cone = (1/3)πr²h.

V = (1/3)π*3²*8.

V = 24π

So, the volume of the conical paper cup will be option (D) 24π
